But this circum- stance records the history of a mighty change in the phenomena of our globe. what it was. Towards the end of the following summer, the entire flank of the animal, and one of its tusks were quite freed from the ice. It was not till the fifth year, that this enormous mass came ashore on a sand bank. In the month of March, 1804, the fisherman removed the tusks and sold them for fifty roubles, &c.
