The tarp, as I have said, should measure 6 x 16. If of canvas, do not get it too heavy, as then it will be stiff and hard to handle. About 10-ounce duck is the proper thing. After you have bought it, lay it out on the floor folded once, as it will be when you have made your bed in it. To the lower half and on both edges, as it lies there, sew a half dozen snap hooks. To the upper canvas, but about six inches in from the edge, sew corresponding rings for the snap hooks. Thus on a cold night you can bundle yourself in without leaving cracks along the edges to admit the chilly air.
In the woods you will want furthermore a rubber blanket. This is unnecessary when the tarpaulin is used. Buy a good poncho. Poor quality sticks badly should it chance to become overheated by the sun.
A six or seven pound blanket of the best quality is heavy enough. The gray army blanket, to be purchased sometimes at the military stores, is good, as is also the "three-point" blanket issued by the Hudson's Bay Company. The cost is from $6 to $8. One is enough. You will find that another suit of underwear is as warm as an extra blanket, and much easier to carry. Sleeping bags I do not care for. They cannot be drawn closely to the body, and the resulting air space is difficult to warm up. A blanket you can hug close to you, thus retaining all the animal heat. Beside which a sleeping bag is heavier and more of a bother to keep well aired. If you like the thing occasionally, a few horse blanket pins will make one of your blanket.
It is the purpose of this book to deal with equipments rather than with methods. There are a great many very competent treatises telling you how to build your fire, pitch your tent, and all the rest of it. I have never seen described the woodsmen's method of using a blanket, however. Lie flat on your back. Spread the blanket over you. Now raise your legs rigid from the hip, the blanket of course draping over them. In two swift motions tuck first one edge under your legs from right to left, then the second edge under from left to right, and over the first edge. Lower your legs, wrap up your shoulders, and go to sleep. If you roll over, one edge will unwind but the other will tighten.
