The true discoverer was Stanley, who, in 1888, suddenly had a vision of the range from the south-west shore of Lake Albert. Every one remembers the famous passage:—

"While looking to the south-east and meditating upon the events of the last month, my eyes were directed by a boy to a mountain said to be covered with salt, and I saw a peculiar-shaped cloud of a most beautiful silver colour, which assumed the proportions and appearance of a vast mountain covered with snow. Following its form downward, I became struck with the deep blue-black colour of its base, and wondered if it portended another tornado; then as the sight descended to the gap between the eastern and western plateaus I became for the first time conscious that what I gazed upon was not the image or semblance of a vast mountain, but the solid substance of a real one, with its summit covered with snow.... It now dawned upon me that this must be Ruwenzori, which was said to be covered with a white metal or substance believed to be rock, as reported by Kavali's two slaves."

Stanley had neither the time nor the equipment for mountain expeditions, though to the end of his life Ruwenzori remained for him a centre of romance. It was his "dear wish," as he told the Royal Geographical Society shortly before his death, that some lover of Alpine climbing would take the range in hand and explore it from top to bottom. In 1889 one of his companions, Lieutenant Stairs, made an attempt from the north-west, and reached a height of nearly 11,000 feet. Two years later Dr. Stuhlmann, a member of Emin's expedition, made a bold journey up the Butagu valley on the west, discovered the wonderful mountain vegetation, and nearly reached the snow level. In 1895 came Mr. Scott Elliot, who was primarily a botanist, but who, in spite of bad malaria, managed to struggle as far as 13,000 feet.

Then followed troubles in Uganda, and it was not till 1900 that the work of exploration was resumed. To make the story clear, it is necessary to explain that the range runs practically north and south, and that about half-way it is cut into by two deep valleys—the Mobuku running to the east and the Butagu running to the Semliki on the west. Fort Portal at the northern end is the nearest station; and as from it the eastern side is the more accessible, it was natural that the Mobuku valley should be chosen as the best means of access. In 1900 Mr. Moore reached its head, and ascended the mountain called Kiyanja to the height of 14,900 feet. He had no sight of the range as a whole, but he believed this to be the highest peak, and put the summit at about 16,000 feet. In the same year Sir Harry Johnston followed this route. He ascended to the height of 14,828 feet on Kiyanja, and saw from the Mobuku valley a mountain to the north, which he named Duwoni. He came to the conclusion that the highest altitude of the range was not under 20,000 feet, and in this view he was followed by other travellers, like Mr. Wylde, Mr. Grogan, and Major Gibbons, none of whom, however, actually made ascents of any peak.

The first serious mountaineering expedition was made in 1905 by Mr. Douglas Freshfield and Mr. A. L. Mumm, who suffered from such appalling weather that they had to give up the attempt. Being experienced mountaineers, however, they reached some valuable conclusions. From the plains they had a clear view of the tops, and ascertained that the mountain called Kiyanja at the head of the Mobuku valley was certainly lower than a twin-peaked snow mountain beyond it to the west. They also placed the extreme height of the range at no more than 18,000 feet. Meanwhile Lieutenant Behrens, of the Anglo-German Boundary Commission, had made an elaborate triangulation, and gave to the twin tops of the highest peak altitudes of 16,625 feet and 16,549 feet—measurements, let it be noted, which were only a few hundred feet out. One other expedition, which occupied the close of the same year and the beginning of 1906, deserves mention. Mr. A. F. R. Wollaston, of a British Museum party, found an old ice-axe in a hut (probably left by Mr. Freshfield), and, with a few yards of rotten rope, set off with a companion to climb Kiyanja. He reached a height of 16,379 feet, and also climbed a peak to the north, which he believed wrongly to be Duwoni, and which now very properly bears his name. The whole performance was a brilliant adventure, and Mr. Wollaston has published the story of his travels in a delightful book.*

* From Ruwenzori to the Congo (John Murray).

Such was the position when, in April, 1906, the Duke of the Abruzzi and his party left Italy to solve once and for all the riddle of the mountains. The Duke was perhaps the greatest of living mountaineers. As a rock-climber his fame has filled the Alps, and no name is more honoured at Courmayeur or the Montanvert. He had led Polar expeditions, and had made the first ascent of the Alaskan Mount St. Elias. His experience, therefore, had made him not only a climber but an organizer of mountain travel. It was to this latter accomplishment that he owed his success, for Ruwenzori was not so much a climber's as a traveller's problem. The actual mountaineering is not hard, but to travel the long miles from Entebbe to the range, to cut a path through the dense jungles of the valleys, and to carry supplies and scientific apparatus to the high glacier camps, required an organizing talent of the first order.

The Duke left no contingency unforeseen. He took with him four celebrated Courmayeur guides, and a staff of distinguished scientists, as well as Cav. Vittorio Sella, the greatest of living mountain photographers. So large was the expedition that two hundred and fifty native porters were required to carry stores from Entebbe to Fort Portal. It was not a bold personal adventure, like Mr. Wollaston's, but a carefully planned, scientific assault upon the mystery of Ruwenzori. The Duke did not only seek to ascend the highest peak, but to climb every summit, and map accurately every mountain, valley, and glacier. The story of the work has been officially written,* not indeed by the leader himself, who had no time to spare, but by his friend and former companion, Sir Filippo de Filippi. It is an admirable account, clear and yet picturesque, and it is illustrated by photographs and panoramas which have not often been equalled in mountaineering narratives.

The charm of the book is its strangeness. It tells of a kind of mountaineering to which the world can show no parallel. When Lhasa had been visited, Ruwenzori remained, with the gorges of the Brahmaputra, one of the few great geographical mysteries unveiled. Happily the unveiling has not killed the romance, for the truth is stranger than any forecast. If the Mountains of the Moon are lower than we had believed, they are far more wonderful. Here you have a range almost on the Equator, rising not from an upland, like Kilimanjaro, but from the "Albertine Depression," which is 600 or 700 feet below the average level of Uganda; a range of which the highest peaks are 1,000 feet higher than Mont Blanc, which is draped most days of the year in mist, and accessible from the plains only by deep-cut glens choked with strange trees and flowers. The altitude would in any case give every stage of climate from torrid to arctic, but the position on the Line adds something exotic even to familiar mountain sights, draping a glacier moraine with a tangle of monstrous growths, and swelling the homely Alpine flora into portents. The freakish spirit in Nature has been let loose, and she has set snowfields and rock arêtes in the heart of a giant hothouse.
