IN the autumn of 1858 a small party of naturalists, most of them members of the University of Cambridge and their friends and all of them interested in the study of ornithology, met in the rooms of the late Professor Alfred Newton at Magdalene College, Cambridge, and agreed to found a society with the principal object of producing a quarterly Journal of general ornithology. The Journal was called "The Ibis," and the Society adopted the name of British Ornithologists' Union, the number of members being originally limited to twenty.In the autumn of 1908 the Society, which by that time counted four hundred and seventy members, adopted the suggestion, made by Mr. W. R. Ogilvie-Grant, of celebrating its jubilee by sending an expedition to explore, chiefly from an ornithological point of view, the unknown range of Snow Mountains in Dutch New Guinea. A Committee, whose Chairman was Mr. F. D. Godman, F.R.S., President and one of the surviving original members of the Society, was appointed to organise the expedition, and subscriptions were obtained from members and their friends. The remote destination of the expedition aroused a good deal of public interest. The Royal Geographical Society expressed a desire to share in the enterprise, and it soon became evident that it would be a mistake to limit the object of the expedition to the pursuit of birds only. Mr. Walter Goodfellow, a naturalist who had several times travelled in New Guinea as well as in other parts of the world, was appointed leader of the expedition. Mr. W. Stalker and Mr. G. C. Shortridge, both of whom had had wide experience of collecting in the East, were appointed naturalists. Capt. C. G. Rawling, C.I.E., 13th Somersetshire Light Infantry, who had travelled widely in Tibet and mapped a large area of unknown territory in that region, was appointed surveyor, with Mr. E. S. Marshall, M.R.C.S., L.R.C.P., who had just returned from the "Furthest South" with Sir E. H. Shackleton, as assistant surveyor and surgeon; and the present writer, who had been medical officer, botanist, and entomologist on the Ruwenzori Expedition of 1906-7, undertook the same duties as before.Prolonged correspondence between the Foreign Office and the Dutch Government resulted, thanks largely to the personal interest of Sir Edward Grey and Lord Acton, British Chargé d'Affaires at the Hague, in permission being granted to the expedition to land in Dutch New Guinea on or after January 1, 1910. The date of landing was postponed by the Government until January in order that there might be no interference with the expedition of Mr. H. A. Lorentz, who it was hoped would be the first to reach the snow in New Guinea by way of the Noord River, a project which he successfully accomplished in the month of November, 1909.VOYAGE TO JAVAOn October 29th four of us sailed from Marseilles in the P. & O. S.S. Marmora. Mr. Stalker and Mr. Shortridge, who had already proceeded to the East, joined us later at Batavia and Amboina respectively. At Singapore we found the ten Gurkhas, ex-military police, who had been engaged for the expedition by the recruiting officer at Darjiling; though some of these men were useless for the work they had to do, the others did invaluable service as will be seen later. We left Singapore on November 26th, and as we passed through the narrow Riou Straits we saw the remains of the French mail steamer La Seyne, which had been wrecked there with appalling loss of life a few days earlier. It was believed that scores of persons were devoured by sharks within a few minutes of the accident happening. Two days' steaming in the Dutch packet brought us to Batavia in Java, the city of the Government of the Netherlands East Indies.
