Nail these 1 x 3 two on each end as directed above, nail to lower piece 2 x 4 only, then at back end bore a hole through the two uprights and also upper 2 x 4, or the piece that falls, put a bolt through, or a wood pin if the hole in the 2 x 4 is larger than those through the uprights; then you are ready to raise it up and let it "drop" to see whether it works smoothly or not.
Better nail a block 2 x 4 between the tops of the uprights to keep them from spreading apart, then it is ready all except the triggers and string for them to run against. It is portable, you can pick it up and move it anywhere, only a stake or two needed driven down on each side. Where string is shown as tied to little bush should be a small stake.

"SHEAR TRAP."
I send a drawing of a trap called the "Shear Trap," writes an Eastern trapper. This is not a new trap, neither is it my own invention. I have used this style and can recommend it to be O. K., cheap, easy made, light to move, will last and will catch most any small animal.
This trap is made as follows: Take 4 strips of board 4 feet 4 inches long, by 3 inches wide. Bore one inch hole two inches from end of all four of them. Now make two rounds about 13 inches long and put two of the boards on each side of the round. At the other end put the two middle boards on the other round (see illustration). Make one other round fifteen inches long, same size as the others. Put the two outside boards on it, forming two separate frames at the other end — so the two inside boards can turn on the round to which they are coupled.
