cessful fly trap which cost for material about fifteen 
cents, and writes that any bright boy can make one of 
them in an hour or two. He took two pieces of board 
one inch thick and about a foot square; tacked them 
together, sawed them round, and in the center sawed 
a hole eight inches in diameter. He then separated 
the boards, and into one he fitted a funnel-shaped piece 
of wire screen about ten inches high, which was fas¬ 
tened to the board with tacks driven on the inside of 
the round hole and fastened together funnel-shaped 
with a strand of the wire selvage. A small hole, large 
enough to admit a lead pencil, was left at the apex of 
the funnel for the flies to creep through. He then 
tacked a piece of wire netting, eighteen inches wide, to 
the outside circumference of each of the round boards, 
with the .funnel-shaped wire on the inside. The out¬ 
side of the wire was again fastened with the selvage 
of the wire. On the top he tacked a piece of wire 
screen in such a way that he could readily remove it to 
empty out the flies. He then nailed lengthwise on the 
outside of the trap a few laths to make it more firm. 
He then made feet by screwing into the bottom piece 
containing the funnel four wire coat-hangers about five 
inches high. 
He placed these traps (he made two at the same 
time) one on each side of the front porch, and under 
each he placed a plate with some sugar on it and a cup 
of sweetened water in the plate. Flies were attracted 
by the sugar and sweetened water, and as they flew 
over the bait they crawled through the hole in the fun-
