Mississippi is not the only river on which flood control measures are used, or in which the Engineer Corps is interested. Flood-control dams are to be found in many parts of the country-in the East, middle West, far West and South west.

Plant crossing is certainly the best-known aspect of the fruit and vegetable research at the national plant and soil laboratory at Beltsville, it makes up only one-third of the total work. Nutrition of crops, and soil management studies, development and testing of root-stocks for fruit trees and the causes and control of disease-fungus, bacterial and virus, fill in the picture. There is no space here to tell the whole story of the Bureau’s work.

The Ovimbundu people of Portuguese West Africa, who live in the interior of Angola, have as much of a “sweet tooth” as Americans, but far less sugar, rationed or otherwise, to gratify it. Forty years ago they had no sugar at all, although they grew some sugar cane, and chewed it for its sweet taste.

While the potato is of great importance in the United States, it is in northern and central Europe that it is often the chief starchy food of the common people. In addition to its use as food for man and beast, the manufacture of industrial alcohol and of starch is of much importance.

What subtle discernment inspires an oriole to swing her dainty nest-hammock far out on the lacy tip of an elm bough? What instinct impels a red-cockade woodpecker to drill numerous small resin wells about his nest hole in a living pine?

To the Nile floods of Pharoah times modern civilisation owes the beginning of engineering, surveying, mathematics and other sciences, developed by the Egyptians in order to find their lands again after the floods had obliterated all landmarks. Farther east the Babylonians learned to control the waters of the Tigris and Euphrates Rivers by means of canals and ditches. Still farther east and at about the same time-some four thousand years before Christ-a Chinese engineer was elevated to the emperor’s throne because he was able to control a flood and save the land from the sea.

An American missionary had a harrowing experience with these Cyprians. He was in Benguela, walking peacefully down the main street, which was then only a dirt road. A swarm of the bees flew by and stopped to cluster on his head and body.

The Ovimbundu are as well satisfied if the “Honey Guide” leads them to meat as to honey. They do not follow it unless they are prepared to hunt a live animal, and, if the prey turns out to be dead, a little detail like the odor of decay does not destroy their appetites.

Like many great species of animal, the numbers of Rufous Wallaby on Tasmania have decreased over the years due to hunting and trapping, which has relegated the creature from a very common to a rare inhabitant of the scrubs. The Tasmanian ringtail opossum is probably the most common marsupial of the island, although the species has been much reduced in numbers too. Many color varieties exist, ranging from nearly white to black. The ringtail makes its nests in hollow trees and branches, like a squirrel.

It was in the ground, in an old white ant hill that the ants had abandoned and the bees had taken over: a bee hive. An “ant hill” sounds as if the bees had a mound-like dwelling.
