Insect tra])S were made by ^Ir. S(d)er in 1010 and placedthronghout the grove, and thousands of moths, nmny of thembelonging to the same genus, the Jfolcocera, were caught in thesetrai)s. Lanterns were suspended from the trees beneath whichwere these tin arrangenients, and below was a pan of water onwhich was ])laced a little oil. That arrangement caught thou-sands of moths. That is one method of controlling the enemy. Tlie grove is full of birds. There are nniny blue birds, andnest boxes have been put up. I do not know whether it is a good. 97 plan to eiicourai^c llie birds or ii(»(. The \V(K)dpeckeiS ai/e there,feeding on iiKseuts and tlie beetle larvae nnder the bark. It maybe a good chance to spread (he chestnnt blight, but they help tocontrol tlie moths. They feed on Inindreds of them. Yon seethem linnting everywhere. The insect-loving birds are find the vireos, the red-eyed vireo especially; you find theAmerican redstart; yon find warblers. They arc there lookingfor the moths and weevils. Chickens were placed in the search for grubs and everything they can find and, ofcourse, in doing that they destroy many of the chestnut weevilsand the grubs of other worms. This view shows the chestnut weevil, the Belaninus, on theburr. These can be controlled by removing the burrs imme-diatel}^, before they have time to come out on the nut. This view shows them
