As examples of the way in which the above Tables should be applied, I will now give three dietaries, in which the quantity of real nutriment has been calculated.
N.B.--Besides this, is beer (in harbour only) sixteen ounces, or spirits four ounces.
Table II. shows the daily food actually consumed by probably the most energetic travelling and exploring party on record. It was during Dr. Rae's spring journey to the Arctic shores of America. He issued, in addition, four ounces of grease or alcohol a day, as fuel for cooking. He found that it required nearly as much fuel to melt the snow, as it did to boil it afterwards. This allowance was found quite sufficient, but there was nothing to spare.
Game was occasionally shot, by which the serious deficiency in Class N must have been supplied. At the same time, I must say that Australian explorers seem to travel exceedingly well on unusually scanty diets.
Food Suitable for the Stores of Travellers.--The most portable kind of food is, unquestionably, the flesh of cattle; for the beasts carry themselves. The draught oxen used in African and Australian explorations serve as a last resource, when all other food is wanting.
