' What Insects do—Locusts'
H. B. JOHNSTON
The speaker this morning is one of the world's greatest experts on the locust problem, and recently represented Uganda and Tanganyika at the International Locust Conference in Brussels.
It is probably true that locusts have plagued man as long as he has existed on the earth. They are older than the pyramids or the Stone
Age. While modern methods of fighting them have done a lot to combat the menace in certain parts of the world, they still remain the terror of the hot-country farmer.
There are few creatures that multiply at so astonishing a rate, and the Arabs have a saying to the effect that the locust lays ninety-nine eggs, for if it laid a hundred the world could not contain all the tribe that would be produced.
The speaker will describe some ravages by locusts that he has seen, and will tell you about three particular methods used to combat them.
