An expedition starting in winter for a journey of ten days will carry ten days’ supply of food for dogs and men. If the journey exceeds that time, the allowance must be reduced; and sometimes the party will be on the point of starvation. At the end of each day’s journey, it is customary, if the party is to return by the same route, to conceal a day’s supply of food, and thus lighten the load as much as possible. There are several ways of making these deposits. The first requisite is generally to protect the food against wild animals. Poles eight or ten feet high are set upright, and a rude box is made at the top, where the food can be placed. Wolves and foxes are the principal four-footed thieves; they cannot climb, and therefore anything protected in this way is safe from their depredations. Sometimes a hole is made in the ground, and the deposit is placed within it. This can only be safely done in winter, as the soft earth in summer can be dug up by the enterprising and keen-scented animals with very little trouble. A hole in winter can be made secure by pouring water over the replaced earth, and allowing it to freeze. Wolves and foxes can do many things, but they have not yet invented any way to dig through frozen ground. They are wise enough not to attempt it, as they would need a new set of paws every half hour if they followed digging in frozen earth as a means of livelihood. Baron Wrangell, Dr. Kane, and other arctic explorers, when travelling on the ice of the Polar Sea, used to make holes in the bergs and hummocks, and sometimes in the level ice, which frequently gets a thickness of eight or ten feet. After they had made the deposit in a hole of this sort, they would fit a block of ice as nearly as possible to the opening. After inserting the block they poured water into the interstices, and allowed it to freeze, so as to make the place as solid and even as ever. This was a sufficient protection against small animals, but not always against polar bears. These huge beasts would scent out the food, and with their powerful claws they managed to dig into the ice, and help themselves. Even if the food had been put into strong boxes before it was deposited, the beasts did not seem to be hindered in getting at it, as they would break the boxes as easily as a rat would open an egg-shell. Dr. Kane once tried the plan of sealing the food in sheet iron cans pointed at the ends. Sometimes the bears tossed these cans a while, and then abandoned them but they generally managed to throw them about with sufficient violence to break the shell and reach the contents. A healthy and full-grown polar bear is a powerful beast, and has no respect for the laws affecting the ownership of property. [Sidenote: HONEST ABORIGINALS.]
