The same circumstance was noted by Baron Wrangel, but it is not new to the Esquimaux. The sledge runs most glibly when the snow is slightly wet. To obviate in some measure the difficulty thus occasioned, the native covers the sole of his runner with moisture. Dissolving in his mouth a piece of snow, he pours it out into his hand and coats with it the polished ivory sole, and in an instant he has formed a thin film of ice to meet the hardened crystals. ”
