The bergs are coloured by it as well as the pack ice, where the ice is lapped by the sea. When a ship charges against a piece of one-year pack ice, the ice is easily broken and often breaks not only vertically, but horizontally.

The coat varies, in fact, from being very nearly white at the end of winter and early spring when it is in its finest condition. The bear-hunters well know this, several times the price being obtained
