For me my serious illness had all at once interrupted the austere and wild delights of this life of the march and the caravan. But I had now become doubly responsive to the joys of travel amid light and air, freedom and endless space; doubly responsive also to the changing impressions derived from my week of marching through lonely primeval forests, bamboo thickets, and grassy plains--scenes in which, as my friend Richard Kandt, the discoverer of the source of the Nile, so strikingly remarks,[3] every plant, every stone, seems to cry out again to one in the vast solitude but one word: “The desert! the desert!” [Illustration: _C. G. Schillings, phot._ YOUNG MASAI DANCING AND SINGING NEAR MY CAMP.] In the early morning hours of January 15 there was a light continuous rainfall. A short march of only two hours brought us to our camping place on the shore of Lake Nakuro. Far away extended the panorama of the lake, which lay before us filling its hollow bed, with its banks at this season of the year yielding fresh pastures to numberless herds of wild animals, and its waters affording rest and food to countless members of the feathered tribe. I had hardly ever seen greater numbers of the pretty little dwarf gazelles (_Gazella thomsoni_, Gthr.). Thousands and thousands more of these graceful creatures showed themselves on the fresh, green, grassy meadows of the lake margin, or scattered over its pebble beds of obsidian, augite, and pumice-stone. Wherever one turned one’s gaze it fell again and again upon these beautiful gazelles, which in many ways reminded one of wild goats at pasture, and were so strangely trustful that they often allowed the spectator to come quite close to them. Marked as are the colours of its hairy covering, the dwarf gazelle does not stand out boldly from the background, whether this be a plain blackened by bush-fires, or the mere bare ground, dun-coloured and brown, or land covered with soft green grass. But how clearly defined are its brown, black, and white, when we look closely at the hide of a specimen we have secured, or see it in a museum. Darker spots in the distance far away from us we take to be larger wild animals. The field-glass shows that they are hartebeests, and a great number of waterbuck; and still farther off there is a moving mass that shimmers and is half lost in the glare of the morning sun. There are zebras, and yet more zebras, moving like living walls! Strange effects of light actually give us the impression of something like a wall or rampart, made up of the living forms of the zebras--the deep shadows they throw come out black, their flanks are lighted up in the dazzling sunshine, and they shimmer with all colours and with ever-changing effect.
