When wood is scarce and side logs are not to be found, or it is not wise to burn them, stones may be built up to a height of five or six inches. A large stone may close one end if desired, turning it into a three-sided fireplace. Build the fire within as in the regular hunter-trapper. Please avoid water saturated limestone from creek-beds. When the stones are heated, the water in them boils and the stones explode.
Serious injury can result.
More fires will be added soon.
