, the ground work of the following description will be obvious enough. Somewhere along the shore an immense boiling spring discharges its overflow directly into the lake. The specific gravity of the water is less than that of the lake, owing probably to the expansive action of heat, and it floats in a stratum three or four feet thick upon the cold water underneath.
