However, as the warm weather advanced, the quantity of ice instead of melting as was expected, began to increase, and by the middle of July the sides of the shaft were covered with a coating of ice a foot or more thick and large icicles were forming from the opening at the top.

As winter again came on, the ice began to disappear until the cave
