The number of deadfalls and snares that each trapper should construct in his section must largely be determined by himself, depending upon how large a territory he has to trap over without running into other trappers' grounds. It will be little use to build traps where there are other trappers as trouble will occur, traps may be torn to pieces, etc. Yet there are many good places to build traps in your immediate locality no doubt. If there are any creeks near and woods along the banks you will find good places at both creek and in the woods. If in sections where there is no forest, like some western states, deadfalls trapping may be difficult from the fact that there is nothing to build them with. In such cases the portable traps, (described elsewhere) in this book, can probably be used to advantage, but best of all in such places is steel traps. The number of deadfalls and snares that a trapper can attend to is large, from the fact that the game is killed and as the weather is usually cold, the traps need not be looked at only about twice each week. In the North, many trappers have such long lines that they do not get over them only once a week. The trouble where deadfalls are only looked at once in seven days is that other animals are apt to find the game and may injure the fur, or even destroy the pelt. Where snares with spring pole attachment are used, and the weather is cold, the trapper need not make the rounds only once a week, as all animals will be suspended in the air and out of the reach of flesh eaters. South of 40 degrees where the weather is not severe, it is policy to look at traps at least twice a week, and in the extreme South the trapper should make his rounds every day. It will thus be seen that a trapper in the North can attend more deadfalls and snares than one in the South or even in the Central States. No trapper should have more traps or longer lines than he can properly attend to. The fur bearing animals are none too numerous without having them caught and their pelts and fur spoiled before the arrival of the trapper. CHAPTER XXII. WHEN TO TRAP. The proper season to begin trapping is when cold weather comes. The old saying that fur is good any month that has an "r" in does not hold good except in the North. Even there September is too early to begin, yet muskrat and skunk are worth something as well as other furs. In the spring April is the last month with an "r." In most sections muskrat, bear, beaver, badger and otter are good all thru April, but other animals began shedding weeks before. The rule for trappers to follow is to put off trapping in the fall until nights are frosty and the ground freezes.
