It is of immediate consequence that compe- tent volunteers to cooperate in the work be forthcoming. For this part of the country Mr. Lyon has only two associates: one at Hobart, Indiana, and one at Sault Ste Marie. He is anxious to enlist workers between the latter place, and his home sta- tion, Waukegan, and from Chicago southward to Cairo and the Gulf. Supplementing the description of an improved "sparrow trap," which Mr. Lyon gave to the last Bulletin, he now sends memoranda of more recent experiences. He writes as follows: "When the birds began to mate it was apparent that the self-acting traps would soon have to be abandoned, as the traps could not be watched all the time and that would keep the captured birds away from their mates or from their nests when built, so the number of Sieve Traps or Drop Traps, as some may call them, was increased. Details of our experiences with these traps are here offered. "The^ original trap was just a box three feet square and four inches deep with three quarter inch mesh wire netting on the top.
