"Melted snow," Joe replied. "I used to fix one of the basins of dried seal-skin a foot or so above the lamp, so that it would be hot enough to melt the snow without a risk of its burning itself. Then I used to pour the water from one basin to another for half an hour. Melted snow-water is poor stuff if you don't do that. I do not know the rights of it, but I have heard tell that it's 'cause there ain't no air in it, though for my part I never could see no air in water, except in surf. I had heard that that was the way they treated condensed water, and anyhow it was a sort of amusement like, and helped to pass the time."
