How to build a fire
You need three types of materials
Kindling is readily combustible material that you add to the burning tinder. Again, this material should be absolutely dry to ensure rapid burning. Kindling increases the fire’s temperature so that it will ignite less combustible material.
Fuel is less combustible material that burns slowly and steadily once ignited.
HOW TO BUILD A FIRE
There are several methods for laying a fire and each one has advantages. The situation you are in will determine which of the following fires to use.
TEPEE
To make a tepee fire (), arrange the tinder and a few sticks of kindling in the shape of a tepee or cone. Light the center. As the tepee burns, the outside logs will fall inward, feeding the fire. This type of fire burns well even with wet wood.
LEAN-TO
To lay a lean-to fire , push a green stick into the ground at a 30-degree angle. Point the end of the stick in the direction of the wind. Place some tinder deep under this lean-to stick. Lean pieces of kindling against the lean-to stick. Light the tinder. As the kindling catches fire from the tinder, add more kindling.
CROSS-DITCH
To use the cross-ditch method , scratch a cross about 30 centimeters (12 inches) in size in the ground. Dig the cross 7.5 centimeters (about 3 inches) deep. Put a large wad of tinder in the middle of the cross. Build a kindling pyramid above the tinder. The shallow ditch allows air to sweep under the tinder to provide a draft.
PYRAMID
To lay the pyramid fire , place two small logs or branches parallel on the ground. Place a solid layer of small logs across the parallel logs. Add three or four more layers of logs, each layer smaller than and at a right angle to the layer below it. Make a starter fire on top of the pyramid. As the starter fire burns, it will ignite the logs below it. This gives you a fire that burns downward, requiring no attention during the night.
Methods for Laying Fires
There are several other ways to lay a fire that are quite effective. Your situation and the material available in the area may make another method more suitable.
