The next morning we crossed one of the tributaries of the Athi River. It was thickly overgrown from bank to bank with papyrus reeds, and we were consequently obliged to cut a passage. The donkeys had also to be unloaded, and their loads carried across. We got wet up to the knees in the cold, slimy water, which did not add to our comfort. We passed a rhinoceros on the road, but did not stop to shoot him as we were not in want of meat. Crossing another river an hour or so later, we made the passage easily by the simple expedient of wading across up to our middles, without troubling to undress or take our boots off; all except George, who was riding the mule. He declared that he “wasn’t going to get wet!” _we_ could be “silly cuckoos” if we liked! _he_ was “going to ride across.” He attempted it; halfway across the mule slipped into deep water, plunged furiously to recover itself, broke the girth, and George and the mule made a glorious dive together into ten feet of water. Jumping in, I succeeded in getting hold of the mule’s head while George scrambled ashore, gasping with cold. In the mean time Kriger and Knapp with El Hakim had got some distance ahead, leaving George and myself to see the safari safely across. When we reached the other side we found ourselves in a swamp, through which we had to wade for over a mile before reaching firm ground. Then the porters struck in a body, saying they were done up and utterly exhausted, and could go no further. I eventually convinced them, not without a certain amount of difficulty, however, that it would be to their interest to go on. Soon afterwards I got a touch of sun, and my head ached horribly. I then fastened the saddle on the mule with one of the stirrup straps, and rode some of the way. We reached the Nairobi River towards the close of the afternoon, and crossed by clambering over the boulders plentifully strewn about the river bed. Just below were the Nairobi Falls, which are about 100 feet deep, and extremely beautiful. At the foot of the Falls the river flows through a deep, rocky glen, which in point of beauty would take a first prize almost anywhere. Great water-worn boulders, clothed with grey-green and purple mosses, among which the water trickled and sparkled in tiny musical cascades; ferns of rare beauty, and flowers of rich and varied hues, gave an artistic finish to the whole; an effect still further accentuated by the feathery tops of the graceful palms and tree ferns that grew boldly out from the steep and rocky sides of that miniature paradise. We found the others had camped a few yards away from the Falls. Kriger and Knapp had been fishing, and had caught a lot of fine fish; Kriger had also shot a congoni. I had my tent pitched, and immediately turned in, as I felt very tired and feverish. Walking in a broiling sun, and shouting at recalcitrant porters for eight and a half hours, on an empty stomach, is not calculated to improve one physically or morally.
