is cut out of the center of the top to form a door. ‘The portions of 
the top (barrel head) are held together by inch strips (D) placed 
around the opening one-half inch from the edge to form a jamb 
for the door. The door consists of a narrow frame (E) covered 
with screen (F) 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 (H) formed by closely tacking screen wire on the outside of the 
hoops. Four laths (1) (or light 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 project 1 inch at the bottom to form legs (J).
