"You seem uneasy, Uncle," said I, when for about the hundredth time he put down his telescope and walked up and down, muttering to himself.

"No, I am not uneasy," he replied in a dry harsh tone, "by no means."

"Perhaps I should have said impatient," I replied, softening the force of my remark.

"Enough to make me so, I think."

"And yet we are advancing at a rate seldom attained by a raft," I remarked.

"What matters that?" cried my uncle. "I am not vexed at the rate we go at, but I am annoyed to find the sea so much vaster than I expected."

I then recollected that the Professor, before our departure, had estimated the length of this subterranean ocean as at most about thirty leagues. Now we had traveled at least over thrice that distance without discovering any trace of the distant shore. I began to understand my uncle's anger.

"We are not going down," suddenly exclaimed the Professor. "We are not progressing with our great discoveries. All this is utter loss of time. After all, I did not come from home to undertake a party of pleasure. This voyage on a raft over a pond annoys and wearies me."

He called this adventurous journey a party of pleasure, and this great inland sea a pond!

"But," argued I, "if we have followed the route indicated by the great Saknussemm, we cannot be going far wrong."
