would reduce the cost to that of the wire and tacks, which would 
be 45 cents. If a larger number of traps are constructed at one time 
the cost is considerably reduced. 
One of these traps is illustrated in figures 1 and 2. In constructing 
the trap two of the hoops are bent in a circle (18 inches in diameter 
on the inside), and nailed together, the ends being trimmed to give 
a close fit. These form the bottom of the frame (4), and the other 
two, prepared in a similar way, the top (2). The top ((C) of the 
trap is made of an ordinary barrel head with the bevel edge sawed 
off sufficiently to cause the head to fit closely in the hoops and allow

secure nailing. A square, 10 inches on the side, is cut out of the cen- 
ter of the top to form a door. The portions of the top (barrel head) 
are held together by inch strips (77) placed around the opening one- 
half inch from the edge to form a jamb for the door. The door con- * 
sists of a narrow frame (£) covered-with screen (/) well fitted to 
the trap and held in place (not hinged) by buttons (G@). The top 
is then nailed in the upper hoops and the sides (47) formed by closely 
tacking screen wire on the outside of the hoops. Four laths (7) (or 
hight strips) are nailed to the hoops on the outside of the trap to 
act as supports between the hoops, and the ends are allowed to pro-
