To sleep warm outdoors the ground should be as dry and warm as possible. This can be accomplished if need be by a fire built over the intended bed area, the embers raked away and the bed made thereon. The browse bag is then filled and flattened over the heated spot. There is some knack in arranging your covers about you to fit snugly and keep out the night cold. It can be done by a simple trick so as to entirely eliminate the necessity of a sleeping bag.
Lying flat on your back on the browse bag cover yourself with the blanket, kick up your feet rigid from the hips so as to bring the blanket foot end draping over and under the feet, returning the feet to the tick roll the body to the left side and tuck the blanket edge under your right side, reverse the turn and do the same under your left side. Lower the feet, wrap up the shoulders and go to sleep. The blanket is now drawn about you snugly above and below and there is no exposed side to let in the cold air and in rolling over the blanket will tighten about you.
In an emergency one can sleep in most any kind of weather by following a certain Indian method. He carries but one blanket but does not use it to wrap around his body. If the night is not too cold he lights a rather large fire and warms the earth, then he rakes away the coals and lies upon the bare warmed ground pulling the blanket over him. In extreme cold in addition to the above ground warming he heats a large stone before bedtime, rolls it on the ground, curls himself around the mound, and pulls the cover over him, lying with his feet to the fire. He neither wraps the blanket about him nor lies upon it relying on the warmed earth for warmth below.
On chilly nights in addition to the heated ground beneath the bed you can build a big camp fire six feet or so in front of your leanto shelter and the heat will be reflected down upon the sleeper. You must have a windbreak of cloth leanto, boughs, or rocks. The fire should be kept going all night and for this one needs a lot of wood, so carry a larger chopping axe if you are to encounter very low temperatures. Even with this fire it is hard for one man to keep warm and get a good night’s sleep. Two men, however, can change off, watching the fire and sleeping.
