ADDENDUM. 



ANOTHER result of the desiccation of the country from the 

 destruction of forests is the increased damage done by locusts, 

 nights of which are more numerous now than they formerly 

 were. Marsh, in " Man and Nature," says : " The insects 

 most injurious to rural industry do not multiply in or near 

 woods. The locust, which ravages the east with its voracious 

 armies, is bred in vast open plains, which admit the full heat 

 of the sun to hasten the hatching of the eggs, gather no 

 moisture to destroy them, and harbour no birds to feed upon 

 the larvge." And again he says : " It is only since the felling 

 of the forests of Asia Minor and Cyrene that the locust has 

 become so fearfully destructive in those countries. 



In Upper India we find locusts feed by preference on the 

 tops of the highest trees ; where, however, there are different 

 kinds of trees of equal height, there are some which they 

 prefer. Where the country is well wooded, locusts almost 

 confine their ravages to the trees, and hardly touch the crops, 

 and there is not that damage done to the crops that there is 

 in a part of the country devoid of trees. This fact furnishes 

 another reason for planting trees in the uncultivated lands 

 throughout the country.
