That night the spell must have been exceptionally strong. It seemed to me as though I were under some charm, as if I were carried back into the far-off times. There came before my mind much of what the lake had seen in the long vanished past. The lands around me heaved and quaked. Mighty earth-shaping forces were doing their work. I seemed to see before my eyes what happened here in primeval times--how volcanic forces, strange, boundless, and terrible, had built up and given form to the country around me here, destroying all living things, and yet at the same time preparing the conditions for the hotly pulsating waves of life of later days. In my mind I saw pass before me wondrous mighty forms of the animal world of the past, long since extinct. Then--suddenly I started up. What was that? [Illustration: _C. G. Schillings, phot._ FLAMINGOES FLYING DOWN TO THE LAKE MARGIN.] [Illustration: ALFRED KAISER (IN ARAB COSTUME).] A loud trumpeting ran in my ears! Elephants! Were there still extant such herds of elephants as those that I saw coming down there to the lake to drink, rolling themselves in the mud of its banks, and openly making friends with the hippopotami? Just as in the daytime I had noticed the different kinds of antelopes and the zebras, so here I saw again the elephants and hippopotami living their life close together, moving round or beside each other without fear or hesitation. The herd, numbering many hundred heads, was guided to its drinking-place silently and slowly by its aged leader, a female elephant of most exceptional size. Many young elephants were there in company with their mothers. Some very little ones, only a few weeks old, played with their comrades, or knowingly imitated the movements of the older animals in the water, while the old ones took care to prevent the tender young creatures from taking any harm. But it all seemed somehow impossible! Veterans among the most experienced black elephant-hunters had assured me that such huge herds were not to be met with. And if I saw aright in the shimmering moonlight, what a great mass of hippopotami were moving about there before me! And now, paying, no attention to the elephants that were peacefully bathing farther out in the muddy water, they clambered on to the land, and began to graze like cows on the bank among some more of the elephants. It was exactly the same friendly relation that I had seen between the dwarf gazelles and the zebras during the day. Could I be only dreaming? Such a multitude of huge creatures here close to my camp--it could hardly be a reality! [Illustration: GROUP OF GNUS. HARTEBEESTS IN THE BACKGROUND.] [Illustration: _C. G.
