 Mediterranean island of Cyprus where its per capita export value in 1924 ($4.00) was greater than that of grain and grain products and forest products from the United States.

The carob is an evergreen tree with rich glossy evergreen foliage. It blooms in the autumn and, like the orange, carries the young fruit to the end of the next summer.

This tree is in itself an example of two parts of the tree crops thesis; namely, the tree is the best means of getting harvests from steep land and also from arid land.

Everywhere the carob takes second-class land, either rocky or dry. On the plains of Valencia the irrigable land is in oranges and garden crops, but ten feet above the last irrigation ditch the carob and the olive begin making a crop on the rocky hillside of the semi-arid land. This is the case in Majorca, in Cyprus, in Algeria, and on Mt. Carmel, and most Mediterranean lands. Sometimes carob trees cling to hillsides which seem to be almost pure rock. In Sicily it is an indipensable shade tree.
