Table of Contents

The first two decades of the twentieth century will rank as a most distinguished era in the history of exploration, for during them many of the great geographical riddles of the world have been solved. This book contains a record of some of the main achievements. What Nansen said of Polar exploration is true of all exploration; its story is a "mighty manifestation of the power of the Unknown over the mind of man." The Unknown, happily, will be always with us, for there are infinite secrets in a blade of grass, and an eddy of wind, and a grain of dust, and human knowledge will never attain that finality when the sense of wonder shall cease. But to the ordinary man there is an appeal in large, bold, and obvious conundrums, which is lacking in the minutiæ of research. Thousands of square miles of the globe still await surveying and mapping, but most of the exploration of the future will be the elucidation of details. The main lines of the earth's architecture have been determined, and the task is now one of amplifying our knowledge of the groyning and buttresses and stone-work. There are no more unvisited forbidden cities, or unapproached high mountains, or unrecorded great rivers.

"The world is disenchanted; oversoon

Must Europe send her spies through all the land."

It is in a high degree improbable that many geographical problems remain, the solving of which will come upon the mind with the overwhelming romance of the unveilings we have been privileged to witness. The explorer's will still be a noble trade, but it will be a filling up of gaps in a framework of knowledge which we already possess. The morning freshness has gone out of the business, and we are left with the plodding duties of the afternoon.

Some of the undertakings described in these pages have not been completed. The foot of man has not yet stood on the last snows of Everest, or on the summit of Carstensz. One notable discovery I have not dealt with—the great Turfan Depression in the heart of Central Asia, far below the sea level, the existence of which was first established by the Russian, Roborowski, before the close of last century, and the details of which have been described by Sir Aurel Stein in his Ruins of Desert Cathay and Serindia. But Sir Aurel's interest was chiefly in the antiquities of the place, and the more strictly geographical results have not yet been given to the world. Today, if we survey the continents, we find nothing of which the main features have not been already expounded. The Amazon basin might be regarded as an exception, and only a little while ago men dreamed of discovering among the wilds of the Bolivian frontier the remains, perhaps even the survival, of an ancient civilization. It would appear that these dreams are baseless. The late President Roosevelt did, indeed, succeed in putting upon the map a new river, the Rio Roosevelt, 1,500 kilometres long, of which the upper course was entirely unknown, and the lower course explored only by a few rubber collectors—a river which is the chief affluent of the Madeira, which is itself the chief affluent of the Amazon. But now all the tributaries have been traced, and though there is much unexplored ground in the Amazon valley, it consists of forest tracts lying between the rivers, all more or less alike in their general character, and with nothing to repay the explorer except their flora and fauna. Africa is now an open book, even though many parts have been little travelled. The map of Asia alone holds one blank patch which may well be the last of the great secrets—the Desert of Southern Arabia, which lies between Yemen and Oman, 800 by 500 miles of waterless sands. Long ago there were routes athwart it, and hidden in its recesses some great news may await the traveller. But its crossing will be a hazardous affair for whoever undertakes it, since he will have to lean upon the frail reed of milk camels for food and transport. For the rest, the problems are now of survey and scientific enquiry rather than of exploration in the grand manner.

I have many acknowledgments to make. My thanks are due in the first place to Mr. Charles Turley Smith, who has contributed the chapters on Arctic and Antarctic Exploration, subjects on which he is specially equipped to write; and, in order to put the conquest of the two Poles in its proper light, has supplied a sketch of the long story of Polar exploration. I am deeply indebted to Mr. Arthur R. Hinks, the Secretary, and to Mr. Edward Heawood, the Librarian, of the Royal Geographical Society for their help and advice. I have also to express my thanks to Messrs. Constable and Company for permission to reproduce illustrations and to quote from works published by them; to Major G. H. Putnam and Messrs. Seeley, Service, and Company for the same kindness; to Major F. M. Bailey, C.I.E., the British Political Officer in Sikkim, for the story of the Brahmaputra Gorges; and to my friends of the Mount Everest Committee for their assent to my use of their beautiful photographs of that mountain.
