"First, a few hundred yards higher up this valley than where we were working, a herd of nine giraffes stalked slowly and majestically from the forest, and, making their way to a pool of water, commenced to drink. These giraffes remained in the open valley until dark, one or other of them, from time to time, straddling out his forelegs in a most extraordinary manner in order to get its mouth down to the water. No other animals came to drink in the pools between us and the giraffes. Possibly some got our wind before leaving the shelter of the forest, though the evening was very still. But below us, as far as one could see down the valley, the open ground was presently alive with game. One after another, great herds of buffaloes emerged from the forest on either side of the valley and fed slowly down to the water. One of these herds was preceded by about fifty zebras and another by a large herd of sable antelopes. Presently two other herds of sable antelopes appeared upon the scene, and a second herd of zebras, and five magnificently horned old koodoo bulls, whilst rhinoceroses both of the black and white species (the latter predominating in numbers) were scattered amongst the other game, singly or in twos and threes all down the valley. Of course all this great concourse of wild animals had been collected together in the neighbourhood of the valley of the Dett owing to the drying up of all the valleys in the surrounding country, and during the rainy season would have been scattered over a wide area."[10] In 1874, Wood, Selous, Mr. and Lieutenant Garden trekked north, intending to hunt on the Zambesi and Chobe rivers. They left Tati on May 6th and approached the Victoria Falls on June 10th, stopping on the way at Daka, where Wood and Selous killed some elephants, and the latter had a somewhat narrow escape from a charging bull which he managed to kill just at the right moment. On June 27th they viewed the wonderful Falls of Zambesi, and Selous, like all other travellers, goes into ecstasies at their beauty and grandeur. Here they encountered for the first time a rare antelope, the pookoo, which gave Selous much pleasure, for it may be said that from this date he commenced his wonderful collection of African mammals. During, and after, 1874, he never failed to preserve and keep for his own collection all the best specimens of big game he shot, then having unrivalled opportunities for getting the finest trophies. This can, of course, only be achieved when animals are abundant. He often lamented afterwards that he did not take more care to get some buffalo bulls of the first quality, for he certainly saw and killed great numbers in those early years, yet he only kept three or four heads of bulls that were in no way remarkable, when he could have possessed the best specimens in existence. When he wanted them it was too late.
