netting' of %-incli mesh, and is re-enforced around the open end 

 and along the sides at the bottom by No. 8 or No. 10 wire, which 

 is used also around the ajjerture for the door and around the door 

 itself. The angles between the first funnel and the walls of the 

 antechamber are floored with netting, and the final chamber is 

 floored with the same material. The accompanying drawings will 

 enable anybody handy with tools to construct one of these traps in 

 a few hours. These plans are for a trap 3 feet long, a foot and 

 a half wide, and a foot high. At ordinary retail prices the cost of 

 material will be about 70 cents. Paper patterns for the two fun-

nels can be made by first drawing the concentric circles, as shown 

 in Figs. 5 and 6, and then laying off the straight lines, beginning 

 with the longest. The wavy outlines indicate that the pattern is to 

 be cut half an inch outside of the straight lines to allow extra wire 

 for fastening the cones to the top and sides of the trap. Fig. 7 

 shows how all the parts of a trap having the above dimensions may 

 be cut from a piece of netting 4 feet wide and 6 feet long. The full 

 lines in this figure indicate where the netting is to be cut and the 

 broken lines where it is to be bent. The numbers at the angles in 

 Figs. 5, 6 and 7 correspond with those in Fig. 4, which shows in 

 outline the relation of the different parts as they appear when 

 assembled. A trap of the above dimensions is as small as can be 

 used satisfactorily. Where sparrows are very numerous a larger
