When the diver received the encouraging pat on the head, as already related, he descended the ladder to its lowest round. Here, being a few feet below the surface, the buoyancy of the water relieved him of much of the oppression caused by the great weights with which he was loaded. He was in a semi-floating condition, hence the ladder, being no longer necessary, was made to terminate at that point. He let go his hold of it and sank gently to the bottom, regulating his pace by a rope which descended from the foot of the ladder to the mud, on which in a few seconds his leaden soles softly rested. A continuous stream of air-bubbles from the safety-valve behind the helmet indicated to those above that the pumps were doing their duty, and at the same time hid the diver entirely from their sight.

Meanwhile the two men who acted as signalman and assistant stood near the head of the ladder, the first holding the life-line, the assistant the coil of air-tubing. Their duty was to stand by and pay out or haul in tubing and line according as the diver’s movements and necessities should require. They were to attend also to his signals—some of which were transmitted by the line and some by the air-tube. These signals vary among divers. With Baldwin and his party one pull on the life-line meant “All right;” four pulls, “I’m coming up.” One pull on the air-pipe signified “Sufficient air;” two pulls, “More air.” (pump faster.) Four pulls was an alarm, and signified “Haul me up.” The aspect of Rooney Machowl’s face when endeavouring to understand Baldwin’s explanation of these signals was a sight worth seeing!

But to return to our diver. On reaching the bottom, Maxwell took a coil of small line which hung on his left arm, and attached one end of it to a stone or sinker which kept taut the ladder-line by which he had descended. This was his clew to guide him back to the ladder. Not only is the light under water very dim—varying of course, according to depth, until total darkness ensues—but a diver’s vision is much weakened by the muddy state of the water at river-mouths and in harbours, so that he is usually obliged to depend more on feeling than on sight. If he were to leave the foot of his ladder without the guiding-coil, it would be difficult if not impossible to find it again, and his only resource would be to signal “Haul me up,” which would be undignified, to say the least of it! By means of this coil he can wander about at will—within the limits of his air-tube tether of course,—and be certain to find his way back to the ladder-foot in the darkest or muddiest water.

Having fastened the line, the diver walked in the direction of the rock on which he had to operate, dropping gradually the coils of the guiding-line as he proceeded. His progress was very slow, for water is a dense medium, and man’s form is not well adapted for walking in it—as every bather knows who has attempted to walk when up to his neck in it. He soon found the object of his search, and went down on his knees beside the hole already driven into the rock. Even this process of going on his knees was not so simple as it sounds, for the men above were sending down more air than could escape by the valve behind the helmet, and thus were filling his dress to such an extent that he had a tendency to rise off the ground despite his weights. To counteract this he opened the valve in front, let out the superabundant air, got on his knees, and was soon busy at work inserting the charge-tube into the hole and tamping it well home, taking care that the fine wire with which it communicated with the party in the barge should not be injured.

While thus engaged he was watched, apparently with deep interest, by a small crab, a shrimp, and several little fish of various kinds, all of which we may add, seemed to have various degrees of curiosity. One particular little fish, named a goby, and celebrated for its wide-awake nature and impudence, actually came to the front-glass of the helmet and looked in. But the diver was too busy to pay attention to it. Nothing abashed, the goby went to each of the side-windows, but, receiving no encouragement, it made for a convenient ledge of the rock, where, resting its fore-fins on a barnacle, it turned its head a little on one side and looked on in silence. Finding this rather tedious, after a time it went, with much of the spirit of a London street-boy, and, passing close to the shrimp, tweaked the end of one of its feelers, causing that volatile creature to vanish. It then made a demonstration of attack on the crab, but that crustaceous worthy, sitting up on its hind-legs and expanding both claws with a very “come-on-if-you-dare” aspect, bid it defiance.

Meanwhile the charge was laid, and Maxwell rose to return to the world above. Feeling a certain uncomfortable hotness in the air he breathed, and observing that his legs were remarkably thin, and that his dress was clasped somewhat too lovingly about his person, he became aware of the fact that, having neglected to reclose the front-valve, his supply of air was now insufficient. He therefore shut the valve and began to wend his way back to the ladder. By the time he reached it the air in his dress had swelled him out to aldermanic dimensions, so that he pulled himself up the ladder-rope, hand over hand, with the utmost ease—having previously given four pulls on his life-line to signal “coming up.” A few seconds more and his head was seen to emerge from the surface, like some goggle-eyed monster of the briny deep.

A comrade at once advanced and unscrewed his front-glass, and then, but not till then, did the men at the pumps cease their labours.

“All right,” said Maxwell, stepping over the side and seating himself on his plank.

“Stand by,” said Baldwin.

The two satellites did not require that order, for they were already standing by with a small electrical machine. The wire before mentioned as being connected with the charge of powder, now safely lodged in the hole at the bottom of the sea, was connected with the electrical machine, and a few vigorous turns of its handle were given, while every eye was turned expectantly on the surface of the sea.

That magic spark which now circles round the world, annihilating time and space, was evolved; it flashed down the wire; the ocean could not put it out; the dry powder received it; the massive rock burst into fragments; a decided shock was felt on board the barge, and a turmoil of gas-bubbles and dead or dying fish came to the surface, in the midst of which turmoil the shrimp, the crab, and the goby doubtless came to an untimely end.

Thus was cleared out of the way an obstruction which had from time immemorial been a serious inconvenience to that port; and thus every year serious inconveniences and obstructions that most people know very little about are cleared out of the way by our bold, steady, and daring divers, through the wisdom and the wonderful appliances of our submarine engineers.

“Now then, Rooney, come an’ we’ll dress you,” said Baldwin. “As you’re goin’ to be a professional diver it’s right that you should have the first chance and set a good example to Mister Berrington here, who’s only what we may call an amateur.”

“Faix, I’d rather that Mister Berrington shud go first,” said Rooney, who, as he spoke, however, stripped himself of his coat, vest, and trousers preparatory to putting on the costume.

“I’ll be glad to go first, Rooney, if you’re afraid,” said Edgar.

Rooney’s annoyance at being thought afraid was increased to indignation by a contemptuous guffaw from Maxwell.

Flushing deeply and casting a glance of anger at Maxwell, the young Irishman crushed down his feelings and said—

“Sure, I’m only jokin’. Put on the dress Mister Baldwin av ye plaze.”

A diver, like a too high-bred lady, cannot well dress himself. He requires two assistants. Rooney Machowl sat down on the plank beside Maxwell, who was busy taking off his dress, and acted according to orders.

First of all they brought him a thick guernsey shirt, a pair of drawers and pair of inside stockings, which he put on and fastened securely. Sometimes a “crinoline” to afford protection to the stomach in deep water is put on, but on the present occasion it was omitted, the water being shallow. Then Baldwin put on him a “shoulder-pad” to bear the weight of the helmet, etcetera, and prevent chafing.

“If it was cold, Rooney,” said his instructor, “I’d put two guernseys and pairs of drawers and stockin’s on you, but, as it’s warm, one set’ll do. Moreover, if you was goin’ deep you’d have the option of stuffin’ your ears with cotton soaked in oil, to relieve the pressure; some do an’ some don’t. I never do myself. It’s said to relieve the pressure of air on the ears, but my ears are strong. Anyway you won’t want it in this water.—Now for the dress, boys.”

The two assistants—with mouths expanded from ear to ear—here advanced with the strong india-rubber garment whose legs, feet, body, and arms are, as we have already said, all in one piece. Pushing his feet in at the upper opening, Rooney writhed, thrust, and wriggled himself into it, being ably assisted by his attendants, who held open the sleeves for him and expanded the tight elastic cuffs, and, catching the dress at the neck, hitched it upwards so powerfully as almost to lift their patient off his legs. Next, came a pair of outside stockings and canvas overalls or short trousers, both of which were meant to preserve the dress-proper from injury. Having been got into all these things, Rooney was allowed to sit down while his attendants each put on and buckled a boot with leaden soles—each boot weighing about twenty pounds.

“A purty pair of dancin’ pumps!” remarked Rooney, turning out his toes, while Baldwin put on his breast-plate, after having drawn up the inner collar of the dress and tied it round his neck with a piece of spare yarn.

The breast-plate was made of tinned copper. It covered part of the back, breast, and shoulders of the diver, and had a circular neck, to which the helmet was to be ultimately screwed. It rested on the inner collar of the dress, and the outer collar—of stout india-rubber—was drawn over it. In this outer collar were twelve holes, corresponding to twelve screws round the edge of the breast-plate. When these holes had been fitted over their respective screws, a breast-plate-band, in four pieces, was placed over them and screwed tight by means of nuts—thus rendering the connection between the dress and the breast-plate perfectly water-tight. It now only remained to screw the helmet to the circular neck of the breast-plate. Previously, however, a woollen night-cap was drawn over the poor man’s head, well down on his ears, and Rooney looked—as indeed he afterwards admitted that he felt—as if he were going to be hanged. He thought, however, of the proverb, that a man who is born to be drowned never can be hanged, and somehow felt comforted.

The diving helmet is made of tinned copper, and much too large for the largest human head, in order that the wearer may have room to move his head freely about inside of it. It should not touch the head in any part, but is fixed rigidly to the breast-plate, resting on the shoulders, and does not partake of the motions of the head. In it are three round openings filled with the thickest plate-glass and protected by brass bars or guards; also an outlet-valve to allow the foul air to escape; a short metal tube with an inlet-valve, to which the air-pump is screwed; and a regulating cock for getting rid of excess of air. The arrangement is such, that the fresh air enters, and is spread over the front of the diver’s face, while the foul escapes at the back of his head. By a clever contrivance—a segmental screw—the helmet can be fixed to its neck with one-eighth of a turn, instead of having to be twisted round several times. To various hooks and studs on the helmet and breast-plate are hung two leaden masses weighing about forty pounds each.

These weights having been attached, and a waist-belt with a knife in it put round Rooney’s waist, along with the life-line, the air-tube was affixed, and he was asked by Baldwin how he felt.

“A trifle heavy,” replied the pupil, through the front hole of the helmet, which was not yet closed.

“That feeling will go off entirely when you’re under water,” said Baldwin. “Now, remember, if you want more air, just give two pulls on the air-pipe—an’ don’t pull as if you was tryin’ to haul down the barge; we’ll be sure to feel you. Be gentle and quiet, whatever ye do. Gettin’ flurried never does any good whatever. D’ee hear?”

“Yis, sur,” answered Rooney, and his voice sounded metallic and hollow, even to those outside—much more so to himself!

“Well, then, if we give you too much air, you’ve only got to open the front-valve—so, and, when you’re easy, shut it. When you get down to the bottom, give one—only one—pull on the life-line, which means ‘All right,’ and I’ll give one pull in reply. We must always reply to each other, d’ee see? because if you don’t answer, of course we’ll think you’ve been suffocated, or entangled at the bottom among wreckage and what-not, or been took with a fit, an’ we’ll haul you up, as hard as we can; so you’ll have to be particular. D’ee understand?”

Again the learner replied “Yis, sur,” but less confidently than before, for Baldwin’s cautions, although meant to have an encouraging effect, proved rather to be alarming.

“Now,” continued the teacher, leading his pupil to the side of the barge, “be sure to go down slow, and come up slow. Whatever you do, do it slow, for if you do it fast—especially in comin’ up—you’ll come to grief. If a man comes up too fast from deep water, the condensed air inside of him is apt to swell him out, and the brain bein’ relieved too suddenly from the pressure, there’s a rush of blood to it, and a singin’ in the ears, and a pain in the head, with other unpleasant symptoms. Why,” continued Baldwin, growing energetic, “I’ve actually known a man killed outright by bein’ pulled up too quick from a depth of twenty fathoms. So mark my words, lad, and take it easy. If you get nervous, just stop a bit an’ amuse yourself with thinkin’ over what I’ve told you, and then go on with your descent.”

At this point Rooney’s heart almost failed him, but, catching sight of Maxwell’s half-amused, half-contemptuous face, he stepped resolutely on the ladder, and began to descend in haste.

“Hold on!” roared Baldwin, laying hold of the life-line. “Why, man alive, you’re off without the front-glass!”

“Och! Whirra! So I am,” said Rooney, pausing.

“Pump away, lads,” cried Baldwin, looking back at his assistants.

“Whist! What’s that?” asked the pupil excitedly, as a hissing sound buzzed round his head.

“Why, that’s the air coming in. Now then, I’ll screw on the glass. Are you all right?”

“All right,” replied Rooney, telling, as he said himself afterwards, “one of the biggist lies he iver towld in his life!”

The glass was screwed on, and the learner was effectually cut off from all connection with the outer air, save through the slight medium of an india-rubber pipe.

Having thus screwed him up—or in—Baldwin gave him the patronising pat on the helmet, as a signal for him to descend, but Rooney stood tightly fixed to the ladder, and motionless.

Again Baldwin patted his head encouragingly, but still Rooney stood as motionless as one of the iron-clad warriors in the Tower of London. The fact was, his courage had totally failed him. He was ashamed to come up, and could not by any effort of will force himself to go down.

“Why, what’s wrong?” demanded Baldwin, looking in at the glass, which, however, was so clouded with the inmate’s breath that he could only be seen dimly. It was evident that Rooney was speaking in an excited voice, but no sound was audible through that impervious mass of metal and glass. Baldwin was therefore about to unscrew the mouth-glass, when accident brought about what Rooney’s will could not accomplish. In attempting to move, the poor pupil missed his hold, or slipped somehow, and fell into the sea with a sounding splash.

“Let him go, boys—gently, or he’ll break everything. A dip’ll do him no harm,” cried Baldwin to the alarmed assistants.

The men let the life-line and air-tube slip, until the rushing descent was somewhat abated, and then, checking the involuntary diver, they hauled him slowly to the surface, where his arms and open palms went swaying wildly round until they came in contact with the ladder, on which they fastened with a grip that was sufficient to have squeezed the life out of a gorilla.

In a few seconds he ascended a step, and his head emerged, then another step, and Baldwin was able to unscrew the glass.

The first word that the poor man uttered through his porthole was “Och!” the next, “Musha!”

A burst of laughter from his friends above somewhat reassured him, and again the tinge of contempt in Maxwell’s voice reinfused courage and desperate resolve.

“Why, man, what was your haste?” said Baldwin.

“Sure the rounds o’ yer ladder was slippy,” answered Rooney, with some indignation. “Didn’t ye see, I lost me howld? Come, putt on the glass an’ I’ll try again. Never say die was a motto of me owld father, an’ it was the only legacy he left me.—I’m ready, sur.”

It is right here to remark that something of the pupil’s return of courage and resolution was due to his quick perception. He had time to reflect that he really had been at, or near, the bottom of the sea—at all events over head and ears in water—for several minutes without being drowned, even without being moistened, and his faith in the diving-dress, though still weak, had dawned sufficiently to assert itself as a power.

“Ha! My lad, you’ll do. You’ll make a diver yet,” said Baldwin, when about to readjust the glass. “I forgot to tell you that when your breath clouds the front-glass, you’ve only got to bend your head down, and wipe it off with your night-cap. Now, then, down you go once more.”

This time the pat on the head was followed by a descending motion. The mailed figure was feeling with its right foot for the next round of the ladder. Then slowly—very slowly—the left foot was let down, while the two hands held on with a tenacity that caused all the muscles and sinews to stand out rigidly. Then one hand was loosened, and caught nervously at a lower round—then the other hand followed, and thus by degrees the pupil went under the surface, when his helmet appeared like a large round ball of light enveloped in the milky-way of air-bubbles that rose from it.

“You’d better give the signal to ask if all’s right,” said Edgar, who felt a little anxious.

“Do so,” said Baldwin, nodding to the assistant.

The man obeyed, but no answering signal was returned.

According to rule they should instantly have hauled the diver up, but Baldwin bade them delay a moment.

“I’m quite sure there’s nothing wrong,” he said, stooping over the side of the barge, and gazing into the water, “it’s only another touch of nervousness.—Ah! I see him, holdin’ on like a barnacle to the ladder, afraid to let go. He’ll soon tire of kickin’ there—that’s it: there he goes down the rope like the best of us.”

In another moment the life-line and air-pipe ceased to run out, and then the assistant gave one pull on the line. Immediately there came back one pull—all right.

“That’s all right,” repeated Baldwin; “now the ice is fairly broken, and we’ll soon see how he’s going to get on.”

In order that we too may see that more comfortably, you and I, reader, will again go under water and watch him. We will also listen to him, for Rooney has a convenient habit of talking to himself, and neither water nor helmet can prevent us from overhearing.

True to his instructions, the pupil proceeded to fasten his clew-line to the stone at the foot of the ladder-rope, and attempted to kneel.

“Well, well,” he said, “did ye iver! What would me mother say if she heard I couldn’t git on my knees whin I tried to?”

Rooney began this remark aloud, but the sound of his own voice was so horribly loud and unnaturally near that he finished off in a whisper, and continued his observations in that confidential tone.

“Och! Is it dancin’ yer goin’ to do, Rooney?—in the day-time too!” he whispered, as his feet slowly left the bottom. “Howld on, man!”

He made a futile effort to stoop and grasp the mud, then, bethinking himself of Baldwin’s instructions, he remembered that too much air had a tendency to bring him to the surface, and that opening the front-valve was the remedy. He was not much too soon in recollecting this, for, besides rising, he was beginning to feel a singing in his head and a disagreeable pressure on the ears, caused by the ever-increasing density of the air. The moment the valve was fully opened, a rush out of air occurred which immediately sank him again, and he had now no difficulty in getting on his knees.

“There’s little enough light down here, anyhow,” he muttered, as he fumbled about the stone sinker in a vain attempt to fasten his line to it, “sure the windy must be dirty.”

The thought reminded him of Baldwin’s teaching. He bent forward his head and wiped the glass with his night-cap, but without much advantage, for the dimness was caused by the muddiness of the water.

Just then he began to experience uncomfortable sensations; he felt a tendency to gasp for air, and became very hot, while his garments clasped his limbs very tightly. He had, like Maxwell, forgotten to reclose the breast-valve, but, unlike the more experienced diver, he had failed to discover his omission. He became flurried and anxious, and getting, more and more confused, fumbled nervously at his helmet to ascertain that all was right there. In so doing he opened the little regulating cock, which served to form an additional outlet to foul air. This of course made matters worse. The pressure of air in the dress was barely sufficient to prevent the water from entering by the breast-valve and regulating cock. Perspiration burst out on his forehead. He naturally raised his hand to wipe it away, but was prevented by the helmet.

Rooney possessed an active mind. His thoughts flew fast. This check induced the following ideas—

“What if I shud want to scratch me head or blow me nose? Or what if an earwig shud chance to have got inside this iron pot, and take a fancy to go into my ear?”

His right ear became itchy at the bare idea. He made a desperate blow at it, and skinned his knuckles, while a hitherto unconceived intensity of desire to scratch his head and blow his nose took violent possession of him.

Just then a dead cat, that had been flung into the harbour the night before, and had not been immersed long enough to rise to the surface, floated past with the tide, and its sightless eyeballs and ghastly row of teeth glared and glistened on him, as it surged against his front-glass. A slight spirt of water came through the regulating cock at the same instant, as if the dead cat had spit in his face.

“Hooroo! Haul up!” shouted Rooney, following the order with a yell that sounded like the concentrated voice of infuriated Ireland. At the same time he seized the life-line and air-tube, and tugged at both, not four times, but nigh forty times four, and never ceased to tug until he found himself gasping on the deck of the barge with his helmet off and his comrades laughing round him.

“It’s not a bad beginning,” said Baldwin, as he assisted his pupil to unrobe; “you’ll make a good diver in course o’ time.”

Baldwin was right in this prophecy, for in a few months Rooney Machowl became one of the best and coolest divers on his staff.

We need not try the reader’s patience with an account of Edgar’s descent, which immediately followed that of the Irishman. Let it suffice to say that he too accomplished, with credit and with less demonstration, his first descent to the bottom of the sea.
