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. [Illustration: PORTABLE WOODEN TRAP.] Take two strips three inches wide, two feet and six inches long. Bore one inch hole two inches from the top end and put round broom stick thru it seventeen inches long. Fasten all the rounds by wedges or small wooden pins. Stand the two strips last mentioned on the outside of the frame at the end they separate and make them fast so as to stand perpendicular. For bait stick take lathe or one-half inch board one inch wide. Bore hole as shown in cut (figure 6) cut notch (figure 2). For trigger any stick 18 inches long, 5/8 inch thick will do: tie string 2 inches from end and tie other end at figure 1, pass the short end under round from the outside (figure 3) and catch in notch in bait lath (figure 2), the other end bait at figure 4. Put weight at figure 5. Cover trap at figure 6 to keep animal from going in from back up to figure 7. For bait I use fresh fish, muskrat, bird, etc., and scent with honey or blood. * * * THE BARREL TRAP. I promised in my last letter to describe the barrel trap, says a Northwestern trapper, which I use for capturing rats. Other trappers may have used this trap for years, but I only mean this for the young trappers who know nothing about this trap. Take any kind of an old barrel made of hard wood (a salt barrel makes a good one), and fix a board on one side of the top with a hinge. Let one end of the barrel project out directly over the barrel to within about 5 or 6 inches of the other side. Arrange it so that the end of the board not over the barrel is a little the heaviest so when the rat tilts down the end in the barrel it will come back to place again. Place a bit of parsnip apple, or celery near the end of the board over the barrel so when the rat reaches his front feet over on the board it will tilt down and let him in the barrel to stay. Bury the barrel near a river or creek to within about 2 or 3 inches of top of barrel, so there will be from 6 inches to 1 foot of water in the barrel. If there is much water in the barrel the most of the rats will be dead when you visit your traps. Several may be captured in one night in this kind of a trap. * * * BLOCK TRAP.
