The United States Department ofAgriculture has made extensive inves-tigations regarding the relation of theEnglish Sparrows to man. As a resultof the examination of over six hundredstomachs it was decided that these birdswere a serious pest. Th<^se investigationsalso showed that the food of the younginstead of being exclusively insectivor-ous, as is the case with the young ofprobably all (^f our native sparrows,fully one-third of their food consistedof grain. Only about two per cent, oftheir food was weed seeds. The remain-der of the food consisted of insects,many of which are of harmful species,but the .-niionnt of strain ihat thcv con- 20J. FROM ecu.
