to tent wall, and fasten top end with wire so that the wind will 

 not shake it about. Replace the dirt completely around and 

 over both stovepipe and can until level with ground both out- 

 side and inside of tent. There should be not less than three 

 inches of dirt between any part of the stovepipe or can and the 

 tent, since the latter is sure to be scorched if this precaution is 

 not taken. 



That is really all there is to this heater, and after constructing 

 it the wood may be placed in the "fire place" and lighted.

Do not expect your fire place to work from the start — before 

 a good draught up the chimney has been created, and before you 

 have properly regulated the size of fire pit and opening for 

 draught. However, with a little practice you will soon be able 

 to have an excellent smokeless fire place, and one that has not 

 taken 25 minutes to construct. The larger the opening inside 

 the tent, the more heat will of course be given off, but the limit 

 here must be governed by the maximum opening you can have 

 without smoking yourself out. With the sheet iron, however, the 

 fire pit can occupy any desired space in the tent, the draught be- 

 ing regulated by means of this cover over the trench- Moreover 

 by raising the "lid" for a moment, mosquitoes and other un- 

 desirable and noxious "fearsome creatures" will be quickly per- 

 suaded to vacate.
