South America is bounded at its northern end by an isthmus and at its southern by a strait. They are the two gateways by which the western side of the Continent, cut off from the western and central portions by a long and lofty mountain range, can be approached from the Atlantic. It was by crossing the Isthmus that Vasco Nuñez de Balboa discovered the South Sea. It was by penetrating the Strait that Magellan, seven years later, discovered that this South Sea was a vast ocean stretching all the way to the coasts of Asia. In old Spanish days all the commerce of the west coast passed over the Isthmus,3 but when the days of steam navigation arrived, that commerce passed through Magellan's Strait. Now the Isthmus itself is to be turned into a strait and will be a channel for sea-borne trade, the main gateway to the West.

An isthmus and a strait are, to the historical geographer and to the geographical historian, the most interesting things with which geographical science has to deal. Commerce and travel and naval warfare concentrate themselves at the spot where a narrow channel connects wide seas, and the strip of land which severs two seas from one another interposes a barrier to water-borne trade and turns it off into other directions. It becomes a point the control of which can stop the march of armies, and it furnishes a central stronghold whence ships can go forth to threaten the neighbouring coasts. Thus every strait and every isthmus has a high commercial importance, and almost always a political importance also, since lines of commerce have usually been, and are now more than ever, potent factors in human affairs, while the command of a water passage for fleets, or that of a land passage for armies, may be of capital importance in war.

The Eastern Hemisphere has an isthmus which has been significant for world commerce and for world history almost from the beginning of civilization. It is the Isthmus of Suez. So the Western Hemisphere has its isthmus of supreme importance, – that of Panama. It is a link between continents and a barrier between seas, which, though its history is far shorter than is that of Suez, yet has been at some moments in the last four centuries, and may be still more hereafter, of high significance for the movements of the world.

There are some notable points of similarity between these two isthmuses. Their breadth is not very different, – Suez sixty miles, Panama about fifty-four. The shortest line across each runs nearly due north and south. The continents which each unites are gigantic. Each lies in what is, or was till quite lately, a practically uninhabited country.

Here, however, the likeness ends; and we come to points of contrast that are more remarkable. The Isthmus of Suez is flat as a table from one end to the other; that of Panama is covered with high and generally steep hills. Suez is an arid waste, where there is not a brook and scarcely even a well, and by consequence not a tree, nor any growing thing save a few thin and thorny shrubs. Panama has a tremendous rainfall in places, varying from one hundred and forty inches a year on the north side to sixty on the south, and is covered with wood so dense that roads have to be not only hewn through the forest but defended by incessant cutting against the efforts of a prolific nature, always seeking to reassert her rights. Having a keen, dry, desert air, the whole Suez region is a healthy one, where man need fear disease only in those few spots which he has in recent years brought under irrigation. Panama had for centuries a climate so deadly that even passing travellers feared to halt more than a few hours on either side of the Isthmus. Yellow fever, intermittent and remittent fevers, and all sorts of other tropical maladies made it their favourite home.

A still more remarkable contrast, however, between these two necks of land lies in the part they have respectively played in human affairs. The Isthmus of Panama must, in far-off prehistoric days, have been the highway along which those wandering tribes whose forefathers had passed in their canoes from northeastern Asia along the Aleutian Isles into Alaska found their way, after many centuries, into the vast spaces of South America. But its place in the annals of mankind during the four centuries that have elapsed since Balboa gazed from a mountain top rising out of the forest upon the far-off waters of the South Sea has been small, indeed, compared to that which the Isthmus of Suez has held from the beginning of history. It echoed to the tread of the armies of Thothmes and Rameses marching forth on their invasions of western Asia. Along the edge of it Israel fled forth before the hosts of Pharaoh. First the Assyrian and afterwards the Persian hosts poured across it to conquer Egypt; and over its sands Bonaparte led his regiments to Palestine in that bold adventure which was stopped at St. Jean d'Acre. It has been one of the great highways for armies for forty centuries, as the canal cut through it is now one of the great highways of commerce.

The turn of the Isthmus of Panama has now come, and curiously enough it is the Isthmus of Suez that brought that turn, for it was the digging of a ship canal from the Mediterranean to the Red Sea, and the vast expansion of Eastern trade which followed, that led to the revival of the old designs, mooted as far back as the days of the Emperor Charles the Fifth, of piercing the American Isthmus. Thus the comparison of the two isthmuses becomes now more interesting than ever, for our generation will watch to see whether the commerce and politics of the western world will be affected by this new route which is now being opened, as those of the Old World have been affected by the achievement of Ferdinand de Lesseps.

So many books have been written, and so many more will be written, about the engineering of the Panama Canal and about its commercial possibilities, that of these very little need be said in such a sketch as this. But as everybody is already curious, and will, two years hence, be still more curious regarding the region it traverses, I shall try to convey some sort of notion of the physical aspects of the Isthmus and of the impressions its past and its present make on the traveller's mind. In taking the reader with me across the neck of land, I shall in the first instance say nothing of the works of the canal which I saw in course of execution, but will ask him to remember that it runs, as does the Trans-Isthmian railway, from north to south, the coast-line both on the Atlantic and on the Pacific side trending in this region east and west.4

Approaching in the steamer from Europe or New York across the Caribbean Sea one sees low hills rising gently from the shore, fringed with palms and dotted with small white houses half hidden among the trees. In front, on an islet now joined to the mainland, is the town of Colon, a new town, with a statue of Christopher Columbus "protecting" a female Indian figure of America, but no buildings of interest and little history, for it is only sixty years old, built as the terminal point of the railway. The old fortified ports where the Spanish galleons used to lie at anchor in former days, Nombre de Dios and Puerto Bello, stand farther to the east. Behind the town, higher hills, covered with those thick, light green woods that characterize the tropics, cut off the view to the south. No depression in the land is visible. There is nothing to suggest that another ocean lies beyond, only fifty miles away, and that here the great backbone which traverses two continents for many thousands of miles sinks to a point a few hundreds of feet above sea level.

The traveller on landing steps into the railroad car, and after running for three miles along the shore of the shallow bay of Limon into which the Canal is to issue, strikes in four miles more the valley of the Chagres River. Here is the point (to be described later) at which the huge Gatun Dam is being built across that valley to flood it and turn it into a navigable lake. Thence the line keeps in the same general south-southeast direction on the east side of the Chagres River, parallel to its course. The Chagres, a muddy and rather languid stream, has in the dry season about as much water as the Scottish Tweed and in the wet season rather more than the Potomac and much more than the Shannon. There are few stations on the way, and at first no dwellings, for the country was uninhabited till the work of canal construction began. Morasses are crossed, and everywhere there is on each side a dense, dark forest. So deep and spongy are the swamps that in places it has been found impossible to fill them up or to lay more than one set of rails upon the surface. So dense is the forest, the spaces between the tree trunks filled by shrubs and the boughs bound together by climbing plants into a wall of living green, that one cannot see more than a few yards into the thicket, and can force a way through it only by the help of the machete, – that long, cutlass-like knife which people carry in Spanish America. Hardly a trail running into the woods is seen, and a mile or two back the wild cats and monkeys, and their terrible enemies, the anacondas or boa constrictors, have the place all to themselves.

After some twenty-three miles of this sort of country, beautiful when the outer boughs of the trees are gay with brilliant blossoms, and pendulous orchids sway in the breeze between their stems, but in September rather monotonous in color, the railway crosses and leaves the Chagres River, whose valley turns northeast far in among higher hills. The line continues to run southward, rising gently between slopes from which the wood has been lately cut away so that one can see the surrounding landscape. All around there is a sort of tossing sea of miniature mountains – I call them mountains because of their steep slopes and pointed crests, though few of them exceed a thousand feet in height. These are set so close together that hardly a dozen yards of level ground can be found between the bases of their declivities, and are disposed so irregularly that they seem as if the product of scattered outbreaks and uplifts of igneous rock. Their sides are clothed and their tops plumed with so thick a growth of wood that the eye cannot discover crags or cliffs, if any there be, and the tops of all are practically unapproachable, because no trails have yet been cut, except to one conspicuous summit. This one rises boldly to a height of about 1200 feet, and has received the name of Balboa Hill, because from it alone in this region – so one is told – can both oceans in a season of fair weather be descried. The gallant Vasco Nuñez deserves the honour of being thus commemorated; but it is to be feared that before long the legend will have struck root among those who dwell here, and will be repeated to those who pass along the canal, that it was from this height, and not from a peak in Darien, seventy or eighty miles farther to the east, that the bold adventurer first looked out over the shining expanse of the South Sea.

We are now more than halfway to the Pacific and may pause to survey the landscape. Though there is moisture everywhere, one sees no water, for neither ocean is visible, the Chagres is hidden among the folds of the hills, and the brooks at the valley bottoms are insignificant. But otherwise it is cheerful and pleasant in its bright green and its varied lines, – a country in which a man might be content to live, faintly reminding one of the Trossachs in Scotland by the number of steep little peaks crowded together and by the profusion of wood. The luxuriance of nature is, however, far greater than in any temperate clime, and the trees have that feathery lightness which belongs to the tropics, their tops springing like green bubbles into the soft blue air.

Here, at a place called Culebra, is the highest part of the crossing from ocean to ocean, 110 feet above sea-level; and as it was here that the deepest cutting had to be made for the canal it is here that the headquarters of the engineering staff has been fixed. Of the cutting more anon. The railway follows a devious course among the hills, rattling here and there through cuttings in hard igneous rock, and in a few miles, descending gently, it passes out into a wide valley, the farther end of which, to the south, is open, with a bold hill guarding it on the east side and several more distant rocky eminences visible far away against the horizon. The hill is Ancon, overlooking Panama city on the one side, and, on the other, the bay which the canal enters. The eminences are islands lying out in the Pacific. Being now quite down on the level of the ocean, we do not see its waters till the railway, passing along the edge of a brackish tidal swamp, reaches the city of Panama, forty-six miles from Colon.

As the Pacific side of the Isthmus is much the most picturesque part of the whole, and impresses itself most on the imagination, the visitor who desires to enjoy the scenery and grasp the configuration of land and sea, ought to climb, if he is an active walker, to the top of the hill of Ancon, on the lower slopes of which, rising just above Panama city, are the United States government offices and the villas of its officials. Steep everywhere, and in parts slippery also, is the foot-path that leads over pastures and through thickets to the top of the hill, some six hundred feet high. But it is worth while to make the ascent, for from the summit one obtains an ample prospect worthy of the historic greatness of the spot.

From this breezy height let the traveller turn his eyes first to the north, and look back over that maze of low forest-covered mountains through which he has passed from Colon and which form the watershed between the two seas. No more from this side of the Isthmus than from the other does one discern any depression in the watershed, any break in the range sufficient to indicate that at this point there is an easy passage from the Atlantic to the Pacific. The hollows through which both railroad and canal pass are hidden deep in the folds of the hills, which stand so thick together that it is hard to believe any waterway could ever be carved out between them and impossible to tell the spot where the cutting is being made.

Very different is the view when the gaze is turned eastward along the far-winding bays and promontories of the Gulf of Panama. There the coast is for a long space flat, and a plain runs back toward distant hills. Beyond this plain other ranges rise to the southeast, bordering the Pacific till they sink below the horizon opposite the Pearl Islands. Somewhere among those ranges is the height to which Balboa climbed and whence he made the great discovery; somewhere along those shores the place where, clad in armour, he strode into the waves, and with sword drawn, took possession of the sea on behalf of the king of Spain. It is rather across that plain that any one looking from this side might fancy the lowest passage from sea to sea would be found. Yet not there, but much farther to the southeast, far behind the hills, in the Gulf of Darien, there is a point still lower, where between the Atrato River which falls into the Caribbean and the River San Juan running to the Pacific a few miles of cut would enable a ship to pass from sea to sea. Now let the traveller turn round and face to the west. His eyes will follow a long mountain chain which rises high and bold from the opposite shore of the Gulf of Panama and runs out southwest until it too is lost to sight beneath the far horizon. In front, a group of rocky isles lies basking in the sunny sea. Just beneath the Ancon hill, at its eastern foot, the little city of Panama stands on its promontory, a mass of grey, red-roofed houses with a half-demolished Spanish fort of the eighteenth century guarding the shallow roadstead, while on the opposite side of the hill, at the base of its steep slopes, is the mouth of the Canal.

The landscape spread out under this hill of Ancon is the finest in all the Isthmian region. The northern side at Colon, although pretty with its abundant verdure, is commonplace; but here there is a view which appeals at once to the eye and to the imagination, ranging over vast stretches of land and sea, rich with varied colour, bringing together the past and the future. Over these smooth ocean plains, which the Spaniards, accustomed to their own stormy Atlantic, called the Peaceful Sea, Vasco Nuñez de Balboa looked eagerly out as he planned that expedition to Peru which the jealous cruelty of Pedrarias, the Spanish viceroy, cut short. Over them the less worthy but more fortunate Pizarro sailed to those far southern lands, where he won, in two years, an empire vaster than that which in the Old World obeyed his sovereign, Charles the Fifth. Backward and forward across these waters came the fleets that bore to the south swarms of fierce adventurers to plunder the native peoples, and that brought back the treasures which supported the European wars of Spain and helped to work her ruin. Three miles off there can be just discerned amid the trees the ancient cathedral tower of the now ruined city of old Panama, where those fleets used to anchor till the English buccaneer Morgan sacked and destroyed the place in 1679. And just beneath, on the opposite side of the hill from these traces of the vanished colonial empire of Spain, the long mole that is to shield the mouth of the Canal is rising, and the steamships lying along the wharves, and cars standing beside them on the railway tracks, presage a commerce vaster than ever was seen in the great days of Spain, for they speak of the passage of men from all the nations along the new waterway through these forests and out over this sea to the ends of the earth. Here, as at the Straits of Gibraltar and on the Bosphorus, nature and history have joined to give delight for the eyes, and to the mind musings on the past and dim forecasting visions of the future.

Save for these few points where human dwellings are seen, – the little Spanish city below and the offices and warehouses that mark the beginnings of the new commercial port and some houses on the islets in the bay, where the inhabitants of Panama seek in summer a cooler air, – it is a lonely landscape, with scarcely a sign of life on land, and as yet few ships flecking the water. The region has always been thinly peopled and its tribes never reached the semi-civilization of the Maya peoples of Yucatan, Honduras, and Guatemala to the north of them, nor of the Chibchas of Bogota to the south. There are, anyhow, no traces of prehistoric progress here, though some have been found in Costa Rica. The aborigines were not numerous in this region, and, after the Spaniards came, were quickly reduced by the attacks which gold-seeking adventurers made upon them. Thus one hears of but few now, except at one place, called San Blas, on the shore of the Caribbean Sea, some forty miles east of Colon. There an Indian tribe has kept itself quite apart from the white intruders, having maintained a practical independence both of Spanish viceroys and republican presidents of Colombia. These Indians are short, strong men, good sailors and fine fighters, men of the same stock that repulsed the first settlers whom Columbus planted near by on his second voyage, and so jealous of their freedom and their own ways that they will not suffer a white stranger to spend the night in one of their villages. They are reported to be still heathens, having their own medicine men, the efficiency of whom is secured by a rule which terminates the professional career together with the life of a practitioner who has lost to death seven patients in succession. These Indians come to Colon in their canoes to trade, and show themselves passably friendly to the Americans there, though less effusively so than their ancestors were to the English in those far-away days when they guided English buccaneers across the Isthmus to pounce upon their Spanish enemies at Panama. When in 1698 the Scottish colonists arrived on their ill-starred expedition to found a colony at Darien, the San Bias men welcomed them with open arms and shewed their good feeling by frequently coming on board and drinking a great deal of liquor. These kindly dispositions lasted down till our own time, for a tale goes that in one of their struggles against the Colombians they declared themselves subjects of Queen Victoria. The Republic of Panama, having plenty of troubles of its own, wisely leaves them alone.

As there are few Indians now in the narrowest part of the Isthmus, so also there are few white people. The Spaniards never tried to settle the country, though they built towns here and there on the coast for trade. There was neither gold nor silver to attract adventurers. The land was covered with jungle, and there was a lack of native labourers to be enslaved and set to clear and till it. The jealous policy of the home government excluded the subjects of all other powers, so most of this region remained a wilderness, unimproved, and parts of it unexplored. A paved road was constructed across the Isthmus from old Panama, the town built by Pedrarias when he crossed to the Pacific side in 1520, to Nombre de Dios, which became the chief port on the Atlantic side; and along this road pack mule trains carried the silver that had come up from Peru to be shipped for Cadiz or Vigo in those great galleons for which the English seamen used to lie in wait. On the Atlantic coast there was held once a year a great fair which lasted six weeks, and to which trading folk came by sea from far and wide. Nearly all the manufactured goods which were consumed in Peru and all down the west coast were sold and bought here. Little else broke the monotonous annals of these remote provinces except the exploits of the English sea-rovers who carried on the war of Protestantism against Spain for the benefit of their own pockets. Sir Francis Drake, the least sordid and most gallant among them, began his exploits by establishing himself in a creek on the Atlantic side of the Isthmus, and thence took Nombre de Dios with a ridiculously small force, and laid ambushes for the silver-carrying mule trains that crossed from Panama, raiding at intervals such Spanish ports as his small force enabled him to capture. In one early expedition, he climbed a tree on a hilltop, and seeing the Pacific from it, fell on his knees and prayed God to give him life till he could sail upon that sea in an English ship – a prayer which was amply fulfilled when he issued from the Straits of Magellan and ravaged the coasts of Peru in 1578. In the last of all his cruises it was in his ship off Puerto Bello that he died in 1596. Eighty years later, Morgan, the famous English buccaneer, gathered a large force of adventurers and seafaring ruffians, crossed the Isthmus by sailing in small boats up the Chagres and thence after a short land journey falling upon Panama, which he took and pillaged, bringing back his booty to the Caribbean Sea. The city was burned, whether by him or by the Spaniards remains in doubt, and thereafter it lay deserted.

Thirty years after Morgan's raid the commercial possibilities of the Isthmus fascinated a Scotsman who had more than the usual fervour and less than the usual caution of his nation. William Paterson, the founder of the Bank of England, led a colony, chiefly composed of Scottish people, and well supplied with Scottish ministers, to a place near Acla in the Gulf of Darien, on the Atlantic side of the Isthmus, one hundred miles southeast of Colon, meaning to make it a great centre of trade over both oceans. They went out, however, imperfectly equipped and ignorant of climatic conditions. Many perished from disease; King William III gave them no support; the Spaniards at last attacked and compelled the surrender of the few who remained. Thereafter nobody disturbed the subjects of the Catholic king. New Panama, planted in a better site where the roadstead is a little deeper, although too shallow for the ocean liners of our own day, continued to enjoy a certain prosperity as the gateway to all western South America, for there was and could be no land transit through the trackless forests and rugged mountains that lie along the coast between the Isthmus and the Equator. But the decline and decay of the colonial empire of Spain under the most ill-conceived and ill-administered scheme of government that selfishness and stupidity ever combined to devise, steadily reduced the importance of the city. Nothing was done to develop the country, which remained, outside Panama and a few other ports, an unprofitable solitude. Neither did the extinction of the rule of Spain, which came quietly here because the local governor did not resist it, make any difference. Occupied with domestic broils, the new republic, first called New Granada and now Colombia, had not the capital nor the intelligence nor the energy to improve the country or develop the commercial possibilities of the Isthmus. This was a task reserved for children of the race which had produced Drake and Morgan.

Thus we come down to the events which have given Panama its present importance. In 1846 Mexico was forced to cede to the United States, as the price of peace, the territories which now constitute the States of California, Nevada, Arizona, and New Mexico. Soon afterwards gold was discovered in California, and a great inrush of settlers followed. There was urgent need for some shorter and safer route to San Francisco than the voyage round Cape Horn or the waggon trail over plains and mountains from the Missouri. Three enterprising Americans obtained in 1848 a concession of the right to build a railway across the Isthmus. The line was opened in 1855, and had, till taken over by the United States government, paid higher dividends continuously (an average down to 1895 of about 15 per cent per annum) than any other line in the world. Being exposed to no competition, it could charge what fares it pleased. A better service of passenger steamers began to run from Panama southward as well as northward; and thenceforward, despite its deadly climate, the Isthmus became a world highway. Though the subsequent opening of railroads across the North American continent reduced the passenger traffic from the eastern United States to California via Panama, the goods or freight traffic continued; and as trade to western South America increased, so the old idea of constructing an interoceanic canal took more definite shape and led to the propounding of scheme after scheme. Finally, in 1878, the success which Ferdinand de Lesseps had achieved at Suez encouraged him to form a company in France to make a sea-level waterway through the Isthmus. This company, formed without sufficient preliminary investigation of the conditions and the cost, collapsed in 1889, having exhausted its funds. A second one, formed in 1894 to resume and complete the enterprise, failed in its turn, after spending many millions, and in 1904 transferred all its rights and interests, together with its plans and its machinery, to the United States government, who, after about two years usefully spent in examining the problem they had to face, began in 1907 that effective work of digging and lock-building which they expect to complete in 1913. They had for some time been trying to obtain a grant from the republic of Colombia of the strip of land required for the excavation of the Canal, but could not secure terms which they thought reasonable. Then, in 1903, a revolt took place at Panama against the authority of Colombia, and the new republic of Panama, which forthwith emerged, gave to the United States a perpetual lease of a strip of ten miles wide, being the space through which the purposed canal was to run. This strip – now called the Canal Zone – is forty-five miles long, with an area of about 448 square miles. The United States Government is practically supreme in it, – though it has been held not to be a part of the United States for the purposes of the Constitution, – and rules it by a Commission under the War Department, being also owner of more than two-thirds of its surface. In return for the lease it has paid a large sum to the little republic and guaranteed its independence. With the strip it has also acquired four small islands, deemed valuable strategically, which lie a little way off the shore opposite the Pacific end of the Canal. They are now to be fortified to protect the approach. The colonial city, with its picturesque fort looking out over the sea, its pretty little plazas planted with trees, its winding old-fashioned streets and big dark churches, stands within the Canal Zone, but is administered by its own government, being the capital of this smallest of all the South American republics. The poorer classes occupy themselves with fishing and sitting in the shade, the upper classes with politics. There is hardly any cultivated land near, but it is hoped that on the high undulating ground some miles to the west the cultivation of vegetables and fruits and whatever else passing vessels may need will presently be established.

Of the Canal itself a few words must now be said, just enough to convey some preliminary general notion of it to those who two years hence, when the time for its formal opening arrives, will be deluged with details.

It will be fifty miles in length, from deep water to deep water, though only forty from tide-end to tide-end. The minimum bottom width will be three hundred feet, the minimum depth forty-one feet, the breadth and depth being, however, for the larger part of its length, greater than these figures. Its highest point above sea-level will be eighty-five feet at the surface of the water and forty feet at the bottom, the depth at this point being forty-five feet; i. e. it will be cut down through the dividing ridge of the Continent to a point forty feet above the two oceans.

The simplest way to realize its character is to consider it as consisting of four sections which I will call (a) the Atlantic Level, (b) the Lake, (c) the Cutting, and (d) the Pacific section (in two levels separated by a lock). The Atlantic Level is a straight channel, unbroken by locks, of eight miles, from deep water at the mouth of the shallow Bay of Limon, a little west of Colon, to Gatun, where it reaches the valley of the Chagres River. Now the Chagres River had always been reckoned as one of the chief difficulties in the way of making a canal. It occupied the bottom of that natural depression along which all surveyors had long ago perceived that any canal must run. But the difficulty of widening and deepening the river channel till it should become a useable canal, was a formidable one, because in the wet season the river swells to an unmanageable size under the tropical rains, sometimes rising over forty feet in twenty-four hours. This difficulty was at last met and the stream ingeniously utilized by erecting right across the course of the Chagres a stupendous dam at Gatun, which by impounding the water of the river turns its valley into a lake. This lake will have along the central channel a depth of from eighty-five to forty-five feet of water, sufficient for the largest ship. At the Gatun dam there are three locks, built of concrete, with a total rise of eighty-five feet, by which vessels will be lifted up into the lake. The lake will fill not only the valley of the Chagres itself, but the bottom of its tributary valleys to the east and west, so that it will cover 164 square miles in all, and will be dotted by many islands. The central and deepest line of this artificial piece of water, nearly twenty-four miles long, is the second of our four canal sections, and will be the prettiest, for the banks are richly wooded. At the point called Bas Obispo, where the Chagres valley, which has been running south-southeast towards the Pacific turns away to the northeast among the hills, the line of the canal leaves the Gatun river-lake, and we enter the third section, which I have called the Cutting. Here hills are encountered, so it became necessary, in order to avoid the making of more locks, to cut deep into the central line of the continent, with its ridge of rock which connects the Cordilleras of the southern continent with the Sierras of the northern. After five miles of comparatively shallow cutting southward from the Lake, a tall and steep eminence, Gold Hill, the continental watershed, its top 665 feet high, bars the way. Through it there has been carved out a mighty gash, the "Culebra Cut," of which more anon. A little further south, eight miles from the Lake, the ground begins to fall rapidly towards the other sea, and we reach the fourth or Pacific section at a point called Pedro Miguel. Here is a lock by which the Canal is lowered thirty feet to another but much smaller artificial lake, formed by a long dam built across the valley at a spot called Miraflores, where we find two more locks, by which vessels will be lowered fifty-five feet to the level of the Pacific. Thence the Canal runs straight out into the ocean, here so shallow that a deep-water channel has been dredged out for some miles, and a great dyke or mole erected along its eastern side to keep the southerly current from silting up the harbour. From Pedro Miguel to Miraflores it is nearly two miles, and from the locks at the latter to the Pacific eight miles, so the length of this fourth Pacific section, which, unlike the Atlantic section, is on two different levels divided by the Miraflores dam and locks, is ten miles. In it there has been comparatively little land excavation, because the ground is flat, though a great deal of dredging, both to carry a sea channel out through the shallow bay into the open Pacific, and also to provide space for vessels to lie and load or discharge without blocking the traffic.

Thus the voyager of the future, in the ten or twelve hours of his passage from ocean to ocean, will have much variety. The level light of the fiery tropic dawn will fall on the houses of Colon as he approaches it in the morning, when vessels usually arrive. When his ship has mounted the majestic staircase of the three Gatun locks from the Atlantic level, he will glide slowly and softly along the waters of a broad lake which gradually narrows toward its head, a lake enclosed by rich forests of that velvety softness one sees in the tropics, with vistas of forest-girt islets stretching far off to right and left among the hills, a welcome change from the restless Caribbean Sea which he has left. Then the mountains will close in upon him, steep slopes of grass or brushwood rising two hundred feet above him as he passes through the great Cut. From the level of the Miguel lock he will look southward down the broad vale that opens on the ocean flooded with the light of the declining sun, and see the rocky islets rising, between which in the twilight his course will lie out into the vast Pacific. At Suez the passage from sea to sea is through a dreary and monotonous waste of shifting sand and barren clay. Here one is for a few hours in the centre of a verdant continent, floating on smooth waters, shut off from sight of the ocean behind and the ocean before, a short sweet present of tranquillity between a stormy past and a stormy future.

In these forty miles of canal (or fifty if we reckon from deep water to deep water) the two most remarkable pieces of engineering work are the gigantic dam (with its locks) at Gatun and the gigantic cutting at Culebra, each the hugest of its kind that the world has to shew. The dam is nearly a mile and a half long; its base nearly half a mile thick, and it is 400 feet wide at the water line of the lake which it will support. Each of the three locks is double, so that one of the pair can be used by vessels passing from north to south, the other by those passing from south to north. Each has a useable length of 1000 feet, a useable width of 110 feet. They are big enough in length, width, and depth for the largest vessels that were afloat in 1911. He who stands inside one of them seems, when he looks up, to be at the bottom of a rocky glen, "a canyon of cement." Nothing less than an earthquake will affect them, and though earthquakes have been destructive in Costa Rica, two hundred miles away, there is no record of any serious one here. The locks will be worked, and vessels will be towed through them, by electric power, which is to be generated by the fall of the Chagres River over the spillway which carries its water from the lake to the Atlantic.

The great Culebra Cut is interesting not only to the engineer, but also to the geologist, as being what he calls a Section. It is the deepest open cutting anywhere in the world, and shows curious phenomena in the injection of igneous rocks, apparently very recent, among the loose sedimentary beds, chiefly clays and soft sandstones of the latest tertiary epoch. A troublesome result, partly of this intermixture, and partly of the friability and instability not only of the sedimentary strata but also of some of the volcanic rocks, has been noted in the constant slips and slides of rock and earth down the sides of the cutting into the bed of the canal that is to be. This source of expense and delay was always foreseen by those who knew the character of the soil and the power of torrential tropical rains, and was long dwelt upon as a fatal objection to a sea-level canal. It has caused even more delay and more expenditure than was expected. But it has now been overcome, though to avert the risk of future damage to the work when completed the engineers have been obliged to give a much lower slope to the sides of the cutting than was originally contemplated, so that the width of the cutting at the top is also greater than had been planned, and the quantity of material excavated has been correspondingly larger.5 In order to lessen further washing down, the slopes will be sown with creeping grasses and other plants calculated to hold the surface soil.

The interior of the Culebra Cut presented, during the period of excavation, a striking sight. Within the nine miles of the whole cutting, two hundred miles of railroad track had been laid down side by side, some on the lowest level on terraces along which the excavating shovels were at work. Within the deepest part of the cutting, whose length is less than a mile, many hundreds of railroad construction cars and many thousands of men were at work, some busy in setting dynamite charges for blasting, some clearing away the rubbish scattered round by an explosion, some working the huge moving shovels which were digging into the softer parts of the hill or were removing the material loosened by explosions, the rest working the trains of cars that were perpetually being made up and run out of the cutting at each end to dump the excavated material wherever it was needed somewhere along the line of the Canal. Every here and there one saw little puffs of steam, some from the locomotives, some where the compressed air by which power was applied to the shovels was escaping from the pipes, and condensing the vapour-saturated atmosphere.

There is something in the magnitude and the methods of this enterprise which a poet might take as his theme. Never before on our planet have so much labour, so much scientific knowledge, and so much executive skill been concentrated on a work designed to bring the nations nearer to one another and serve the interests of all mankind.

Yet a still more interesting sight is that which meets the visitor when, emerging from the cutting, he crosses to where, behind the western hill, are the quarters of the workers,6 with the cottages of the chief engineer and his principal assistants on the top. The chief engineer, Colonel Goethals, is the head not only of the whole scheme of construction but of the whole administration, and his energy, judgment, and power of swift decision are recognized to have been a prime factor in the progress of the work and the excellence of the administrative details. The houses, erected by the United States government, are each of them surrounded on every floor by a fine wire netting which, while freely admitting the air, excludes winged insects. All the hospitals have been netted so carefully that no insect can enter to carry out infection from a patient. Every path and every yard is scrupulously clean and neat. Not a puddle of water is left where mosquitoes can breed, for every slope and bottom has been carefully drained. Even on the grass slopes that surround the villas at Ancon there are little tile drains laid to carry off the rain. With the well-kept lawns and the gay flower-beds, the place has the air of a model village. And one sees the same in the other quarters of the employés all along the canal line, at Gatun, at Miraflores, at Ancon, where is the great hospital and where have been set up the offices of the civil government which does everything for its employés, both white and coloured. Nowhere perhaps in the world are workpeople so well cared for, and such ample and almost luxurious provision made for comfort and amusement as well as for health by the benevolent autocracy which presides over everything. Its success in escaping all charges of partiality or corruption, as well as in producing efficiency in the work and contentment among the workers, has indeed been such as to make some persons draw from it an argument in favour of State control of all great enterprises. To the unbiassed observer it is rather an instance of the efficiency obtainable by vesting full administrative control in men whose uprightness and capacity have already been proved beyond question, who have not risen by political methods, and who have nothing to gain by any misuse of their powers. So far as any political moral can be drawn from the case, that moral recommends not democratic collectivism but military autocracy.

In these wire nettings and drainage arrangements and hospital precautions, to which I have referred, more than in anything else is to be found the reason why, after the French effort to build the canal had twice failed, the present enterprise is succeeding. The French engineers had shown great skill and were doing their work well. No one admits their merits more fully than do, with the generous candour that belongs to true soldiers and true men of science, the American engineers who have come after them. But they had no means of fighting the yellow fever and the malaria that were frustrating all their skill and exhausting all their resources. The discovery, made while the United States troops were occupying Cuba after the war of 1898, that yellow fever is due to the bite of the Stegomyia carrying infection from a patient to a healthy person, and that intermittent fevers are due to the bite of the Anopheles, similarly bearing poison from the sick to the sound, made it possible to enter on a campaign for the prevention of these diseases among the workers on the Isthmus. This was done before excavation began, and done so efficiently that the Isthmus is now as healthy as any part of the United States. No case of yellow fever has occurred since 1905. The mortality is no higher than in the United States army generally. In 1910 the death rate among 50,802 employés of both colours in the Canal Zone was 10.98 per thousand, in 1911, among 48,876, it was 11.02, – an extraordinarily low rate when compared with the average of European and North American cities. Among the American white employés and their families the rate was only 6.01.7 The white employés and their families are healthy and fresh-looking, with none of that sickly brownish-yellow hue which usually marks the inhabitants of malarial districts. And I can confirm what many other visitors have told me, that one may be for days and nights on the Isthmus and neither see nor hear nor feel a mosquito. To have made one of the pest-houses of the world, a place with a reputation like that of the Pontine Marshes, or Poti on the Black Sea, or Sierra Leone itself, as healthy as Boston or London is an achievement of which the American medical staff, and their country for them, may well be proud; and the name of Colonel Gorgas, the head of that medical staff to whose unwearied zeal and care this achievement is largely due, deserves to stand on the roll of fame beside that of Colonel Goethals, the chief engineer and Chairman of the Commission, who has directed, and is bringing to its successful issue, this whole great enterprise.

The sanitation of the Canal Zone, following that of Havana, has done more than make possible the piercing of the Isthmus. It has opened up possibilities for the settlement by Europeans of, and for the maintenance of permanent European population in, many tropical districts hitherto deemed habitable by their natives only. To the effect of such an example one can hardly set bounds.

In no previous age could an enterprise so vast as this have been carried through; that is to say, it would have required a time so long and an expenditure so prodigious that no rational government would have attempted it. Pharaoh Necho may have, as Herodotus relates, dug a canal across the Isthmus of Suez by the labour of hundreds of thousands of his subjects accustomed to implicit obedience, but his ditch was probably a small and shallow one, and it was through a dead level of sand and clay that it was dug. Here there was a mountain to pierce and a torrent to bridle, and the locks had to provide for vessels a thousand feet long. Nothing but the new forces which scientific discovery has placed in the hands of the modern engineer – steam, electricity, explosives of high power, machinery capable of raising and setting in their place one above another huge masses of cement – would have made the work possible. Yet even that was not enough. The French company possessed such appliances, and though their estimates of cost turned out to be based on totally inadequate data, the competence and energy of their engineers have never been questioned. And the French company failed hopelessly; and failed not merely because the work turned out heavier, and the loose strata giving way under the downpours of rain made the slides and landslips far worse, than was expected.8 These things doubtless told against them, and much of the money raised never found its way to the Isthmus. But it was a more terrible force that foiled them. It was Pestilence, Pestilence coming on the gauzy wings of the mosquito. So little did they recognize their foe that when they built the large and commodious hospital at Ancon they provided, outside the windows, flower-boxes where stagnant water gathered and mosquitoes were hatched. Engineers died, foremen died, labourers were mown down by hundreds. Yet even if all the French capital had been properly spent and better sanitary measures had reduced the pestilential conditions, it may be doubted whether the French company could have made a success of the undertaking. More capital would have been needed, capital which must have been raised on onerous terms, and when it had all been spent and the work completed the profits of the canal could not, after providing for working expenses, have paid interest on half of the money borrowed. Whoever looks at this prodigious work feels that it could be carried through only by a nation commanding resources so overflowing that it does not need to care how much it spends, a nation which can borrow as much money as it pleases without sensibly affecting the quotations of its existing national debt.

It is expected that the construction of the Canal will be found, when it is finished, to have cost nearly £80,000,000 ($400,000,000).9 To this there will have to be added the cost of the fortifications it is intended to erect at Colon and on the islands that lie in the Gulf of Panama, opposite the south end of the Canal, as well as of barracks for the large garrison which is to defend it. The visitor who sees the slopes where these forts and batteries are to be placed asks who are the enemies whom it is desired to repel. Where is the great naval power that has any motive either of national enmity or of self-interest sufficient to induce it to face the risks of a war with a country so populous, so wealthy, and so vigorous as the United States? He is told that there is at present no such naval power, and that no quarter can be indicated whence danger will arise; but that it is possible that at some future time, from some unknown direction, some yet unconjectured enemy may arise against whose possible attacks provision ought now to be made.

When the Canal has been opened and the interest now felt in getting it completed by the appointed day has ended, hardly less keen will be the interest in that other question on which men have speculated so long. What difference will this new waterway from ocean to ocean make to world commerce and therewith also, though probably in a less degree, to world politics? And what difference, to descend to smaller matters, will it make to the West Indies, and to the ports of the Gulf of Mexico, and (not so much commercially as politically) to the neighbouring states of Central and South America? The political side of the matter is one too delicate to be discussed here, but upon the commercial one a word or two may be said.

The new route will doubtless become an important route for the traffic in heavy freight from the Atlantic ports of the United States, and from European ports also, to the ports of western North America.

It will similarly become the main freight line for goods of all kinds from both European and eastern North American ports to the west coast of South America as far south as Callao, and also from Gulf of Mexico ports as far as Coquimbo or Valparaiso. Whether the freight traffic from Europe to Valparaiso and the other ports of Chile will be greatly affected, is deemed more doubtful. Much will, of course, depend on the tolls fixed for transit through the Canal, which, by the treaty of 1901 between Great Britain and the United States, are to be, like those at Suez, equal between all nations.

The most interesting, because the largest, and also the most doubtful and complicated, question is as to the result upon European commerce to the Far East, – Japan, China, New Zealand, and Australia. It is the most complicated, because many factors enter into it, some of them political as well as commercial. Here the Canal will compete with the Suez Canal route, and (as respects Australia in particular) with the Cape of Good Hope route, and it will also compete with the steamship lines which now ply from Australia and New Zealand to England round Cape Horn. From England to all the Australasian and east Asiatic ports, except those of New Zealand, the Suez route will be shorter than that by Panama.10 From New York, however, the route by Panama to Sydney, Auckland (New Zealand), and Shanghai will be shorter than that via Suez, while to Hong Kong and Manila it will be of practically the same length. It is generally supposed that the Panama tolls will be lower than those now imposed at Suez. Commerce, like other things, changes more quickly in our age than it did in any previous age; yet years may elapse before the full results of the opening of the Canal disclose themselves. Some of the commercial as well as the political consequences which have been due to the making of the Suez Canal were altogether unforeseen. If a dozen of the most important experts were, in 1914, to write out and place in the library of the British Museum and the library of Congress their respective forecasts bearing on this subject, sealed up and not to be opened till A.D. 2000, they might make curious reading in that latter year.

The chief impressions which the scenery of the Isthmus makes on the traveller have already been indicated, – the contrast of the wildness and solitude of the region with its wonderful geographical position, which long ago seemed destined to make it a centre of commerce and population, the contrast of the advantages offered by that position with the slothful neglect of those advantages by its Spanish rulers, the contrast one sees to-day between the busy crowd of workers along this narrow line cut out from the vast forest and the untouched unpeopled nature on each side, the contrast between the black cloud of death that hung over it for four centuries and the sunshine of health and energy which medical science has now poured around it.

But the strongest impression of all is that here one sees the latest, so far as can be foreseen, of any large changes which man is likely to try to work upon the surface of the earth. Tunnels longer than any yet made may be bored through mountains or carried under arms of the sea. The courses of rivers may be diverted. Reservoirs vaster than any we know may be constructed to irrigate arid tracts or supply electric power to cities, and bridges may be built to span straits like the Bosphorus, or railroads, like that recently opened in southern Florida, be carried through the sea along a line of reefs. But nowhere else do there remain two continents to be divided, two oceans to be connected, by a water channel cut through a mountain range.

There is a tale that when the plan for digging a canal at Panama was first mooted, Philip the Second of Spain was deterred from it by the argument, pressed by his clerical advisers, that if the Almighty had wished the seas to be joined, He would have joined them, just as, according to Herodotus, the people of Knidus were deterred by the Delphic oracle from cutting through the isthmus along which their Persian enemies could advance by land to attack them. If Zeus had wished the place to be an island, said the oracle, he would have made it one. But when an age arrived in which commercial and scientific views of nature prevailed against ecclesiastics, it became certain that here a canal would be some time or other made. Made it now has been. It is the greatest liberty Man has ever taken with Nature.
