We are not concerned with the rest of the journey of Captain Bailey and Captain Morshead, which took them upstream to Tsetang, where Nain Singh had gone in 1874, and back to India by the wild country of the Bhutan border. Their evidence may be considered to have finally solved the riddle of how the great river breaks through the highest range on the globe. It does it by means of a hundred miles of marvellous gorges, where the stream foams in rapids, but there is no fall more considerable than can be found in many a Scottish salmon river. I am not sure that the reality is not more impressive than the romantic expectation. The mighty current is not tossed in spray over a great cliff, but during the æons it has bitten a deep trough through that formidable rock wall. Curiously enough, the rivers which break through the Himalaya chose the highest parts of the range through which to cut. South of Pemakochung is the great peak of Namcha Barwa, 25,445 feet high; north of it is the peak of Gyala Peri, 23,460 feet. The distance between these mountains is only some fourteen miles, and through this gap, at an altitude of just under 9,000 feet, flows the great river.
When sceptical people say that Polar exploration has been of no benefit to mankind, it is permissible to think that their judgment is as unsound as their point of view is limited. Not only have Polar explorers added enormously to the scientific knowledge of the world, but they have also materially aided commerce. But even if these voyages had been barren of scientific and commercial results, they would have been infinitely worth making.
For among Polar explorers are many men who must be universally regarded as heroes. No training was more rigorous and dangerous, no work has ever called for more endurance, resource, and courage. A nation which is without its heroes is in a sad plight; a nation which has them and ignores their example can only be looked upon with pity. The spirit of high adventure is one that no country can afford to neglect.
The history of geographical discovery is, in its initial stages, almost solely one of conquest. Men, either for their own or their country's profit--and sometimes for both--went out in search of unknown lands because they wanted to trade with them. Pytheas, who has been described as "one of the most intrepid explorers the world has ever seen," was the first man to bring news of the Arctic regions to the civilized world. He did not pretend to have visited them, but in or about 330 B.C. he set out from Marseilles and journeyed north. During this voyage, which must have lasted for several years, he visited Britain, and then, proceeding to the most northerly point of the British Isles, he heard of an Arctic land called Thule, which at one time of the year enjoyed perpetual day, and at another had to endure perpetual night.
