For nearly a minute Captain Wiggs continued his observation of the on-coming boat. Then, laying aside the glass, he remarked:
“I can’t make anything out of her. It’s a strange boat. Never saw her on the lakes before. And they seem to have an uncommon interest in us. A couple of men on deck are taking turns in looking at us through a telescope.”
“Two men?” asked Fenn, beginning to get excited.
“There are two on deck, but of course there must be more somewhere aboard,” replied the captain.
“And has one of them a—a sort of mean looking face?” went on Fenn.
“Well, from what I can see of him through the glass, he doesn’t look to be a very cheerful chap.”
“I’ll wager it’s those men after us!” exclaimed Fenn, turning to his chums.
“What men?” inquired Captain Wiggs.
“The men who chased us when we were at the elevator fire,” and Fenn told of the adventure.
“I wish you had mentioned that to me before,” said the commander, looking grave. “This thing may be serious.”
