Between the second and third logs cut out a little notch and flatten the under side of this log around the notch; this is to receive the trigger, which is made of a small pole about three inches thick. Put this into the hole and let it come down within ten inches of the floor. Then cut a notch in the side facing the front of the pen and so it will fit up against the under side of the leg with the notch in; now you may make a notch in the trigger about six inches above the top of the pen and on the same side of the trigger that the first notch was made. Now the trigger is ready except adjusting the bait. [Illustration: BEAR ENTERING PEN.] Next lay a binder on top of the pen and upon either end of the short course of logs; pin the binders at either end so the bear cannot raise the top off the pen. You may also lay on three or four logs to weight it down and make it doubly sure. You may pin the first short top log in front to the side logs to keep the front of the pen from spreading. Now we have the body of the pen complete. The door is the next thing in order. The first or bottom log ought to be twelve feet long, but it is not necessary for the balance of them to be that length; flatten the top and bottom of each log so they will lie tight together, also flatten off the inside of the door so it will work smoothly against the end of the pen. Lay the logs of the door onto the first or long log, putting a pin in each end of the logs as you lay them on. Go on this way until you have enough to reach the height of the pen and fully cover the opening. Another way of fastening the door together is to get the logs all ready, then lay them upon the ground and pin two pieces across the door. Either way will do. Now the door being in readiness, put it in its place and drive two stakes in the ground to keep the animal from shoving the door away. If these do not appear to be solid enough to support the door against an onslaught, you may cut a notch in the outside of the stake near the top; get a pole eight feet in length, sharpen the ends, letting one end come in the notch of the stake and the other into the ground; this will hold the door perfectly solid. Cut a slight notch in the top log of the door for the end of the spindle and the next move is to raise the door to the proper height. Set a stud under the door to keep it from falling. Get your spindle ready, flatten the top of either end a little, then cut a stanchion just the right length to set under the spindle on the first top log.
