be kept. Thus passed several hours in comparative quiet.
It must have been about midnight that Tom was suddenly awakened by a feeling as if some one was shaking him. He sat up quickly and called out:
"What's the matter?"
"Eh? What's that? Bless my soul! What's going on?" shouted Mr. Damon.
"Did you shake me?" inquired Tom.
"I? No. What?"
Then they realized that another earth-tremor was making the whole island tremble.
Tom leaped from his blankets, followed by Mr. Damon and Mr. Fenwick, and rushed outside the shack. They felt the earth shaking, but it was over in a few seconds. The shock was a slight one, nothing like as severe as the one in the morning. But it set their nerves on edge.
"Another earthquake!" groaned Mr. Damon. "How often are we to have them?"
"I don't know," answered Tom, soberly.
They passed the remainder of the night sleeping in blankets on the warm sands, near the fire, for they feared lest a shock might bring the shack down about their heads. However, the night passed with no more terrors.
