Thanks to the protection afforded it by the Belgian Government, the northern race of the white, or square-lipped rhinoceros, Ceratotherium simum cottoni, is increasing in the Garamba National Park of the Belgian Congo. This park was specially created in 1938 to preserve the species, whose numbers there were down to about a hundred individuals. They now probably approach 1,000. But the story of the black rhinoceros, Diceros bicornis, is very different. Once common in the savannahs of Katanga, but now exterminated there, it used also to exist in the east of Ruanda, notably in what is now the Kagera National Park. So, in 1958, bearing in mind its success with the white rhinoceros, the National Parks of the Belgian Congo decided to try to reintroduce the black rhinoceros into Kagera. This rhinoceros is still not rare in some parts of Tanganyika Territory, especially in Karagwe district, but that country is separated from the Kagera Park in Ruanda by the River Kagera itself.

The decision to build a dam at Kariba involved the Federal Government and the governments of both Northern and Southern Rhodesia in a vast amount of planning. The resettlement of 50,000 Tonga tribesmen was undertaken at a cost of about £4 million. Plans for the development of three township areas on each side of the new lake are under way.

The following observations on the Long-haired or Schweinfurth's Chimpanzee, Pan troglodytes schweinfurthii, represent several brief but concerted efforts to locate wild chimpanzees in western Uganda in the months of October and November, 1957 and 1958. The authors’ appreciation is extended to Mrs. Belle J. Benchley and to Dr. Ernst Schwarz for reading the manuscript and providing helpful suggestions.

The Queen Elizabeth National Park includes more than half the Uganda coastline of the great lakes Edward and George, as well as the 20-mile-long Kazinga Channel which connects the two. Large schools of hippo are present throughout the length of this coast, and they graze inland each night to a steadily increasing degree. The land area of the park is some 760 square miles, of which at the most 400 can be utilized by the hippo. A careful and conservative estimate gives the population of these animals at not less than 14,000, so that each is restricted to a maximum of 16 acres of grazing. In fact, of course, the hippos graze as near as possible to the waters in which they spend the day, making the actual concentration near the lake shore much higher than this. And there is a large number of other grass-eating animals competing for the same grazing: buffalo, kob, waterbuck and other ungulates as well as elephants, all in large numbers. These, however, are not tied to one particular habitat as are the hippos, and are therefore less likely to be the cause of the overgrazing and beginnings of erosion which are evident.

Topographically Ceylon is a detached portion of the South Indian peninsula. It divides into two climatic regions, known as the Dry and Wet Zones; the latter occupies approximately the south-western quarter of the island. By African standards, dry and wet are relative terms and there may be over 80 inches of rain in the Dry Zone. Even so, rainfall tends to be concentrated and long periods without rain occur. The Wet Zone receives rain during both monsoons, the Dry Zone during the north-east monsoon only. Monsoons sometimes fail and serious droughts are not uncommon.
