ous gas. This gas has no odor and can kill a person before its 
presence is suspected. A slight headache or feeling of pressure 
at the temples is the only warning of carbon monoxide poisoning, 
but even this may not be felt. To prevent the gas from forming, 
make certain that the tent or hut has a hole at the apex and that 
some air can come in from below. If partly overcome by the 
gas, one should get into the open air immediately, keep warm, and 
avoid all exercise or exertion for some time afterwards. 
COOKING 
For cooking, the fire should not be too large. If possible it 
should be built between two logs or stones on which the cooking 
utensils may rest. Another method is to suspend the pot over 
the fire from a pole, the lower end of which is stuck into the 
ground. 
Boiling is the simplest and most practical method of cooking. 
Long boiling is not necessary. If meat is cut into small pieces 
and put in cold water it will be cooked sufficiently by the time 
the water has boiled a couple of minutes. Drink the water in 
which the meat is cooked. 
If snow is used for cooking, place a small amount of it in the 
pot at first, adding more as it melts. If the pot is crammed 
full Gf soft, spongy snow this may act as a blotter, absorbing 
the first water that melts and allowing the bottom of the pot to 
burn. This may be avoided by tipping the pot. 
If you have no pot the simplest method of cooking meat is to 
broil thin strips over hot coals, holding them on the forked end 
of a long stick. Larger pieces can be stuck on a stick and 
suspended over the fire, turning them from time to time.
