All rations intended for use above the snow-line should be packed in tin cans, each of sufficient size to hold between fifty and sixty pounds, and each should be securely soldered. All articles packed in this way should be thoroughly dry and should be packed in a dry, warm room. When secured in this manner they are about as easy to carry as if packed in bags, and can be "cached" anywhere out of the reach of floods and avalanches, with the certainty of being serviceable when wanted. The more perishable articles to be used where camp-fires are possible should also be secured in tin cans. Sacks of flour, corn-meal, etc., should be protected by an outer covering of strong canvas. The experience of last summer showed that the cans of rations intended for use above the snow-line should each contain about the following ration, which may be varied to suit individual taste: Bacon, smoked . . . . . . . . . . . . . . . . . . . . . 10 lbs.

Our experience with oil-stoves showed that they are serviceable. While on the march they can be carried as hand packs in {165} gunny-sacks. Rectangular cans holding about a gallon each, with small screw-tops, were found convenient for carrying coal oil. The experience of Arctic explorers indicates that alcohol would perhaps be better than coal oil to use in snow-camps.
