The Land of Feast and Famine
With our lean purses we visit the trading post to lay in further provisions, but the money we have is like a drop in the bucket down here in the north, where prices are out of all proportion. A hundred-pound bag of flour costs fifteen dollars, a box of ammunition three dollars. In civilization these prices average about four dollars and a dollar thirty respectively. It is even worse at the remoter outposts, where a hundred pounds of flour sometimes cost as much as thirty dollars, and a similar amount of sugar fifty dollars. One can readily imagine, thus, how many white-fox pelts a hunter would have to secure merely to cover his original outlay.
