"We can try," was the answer. "If I had known you wanted to use the tug again to-night I should have kept steam up."

"Well, we didn't know."

The Beaver was out of sight and they did not see the steamboat again until she was turning in at the Penwick dock.

"There she is!" cried Sam.

"Hurry up, Captain Carson!" called out Dick. "If you don't hurry we will lose the fellows we are after, sure."

"I am hurrying as much as I can," replied the captain.

In five minutes more they gained one end of the dock and the Rovers leaped ashore. The Beaver was at the other end, discharging passengers at one gang plank and freight at another.

"See anything of them?" asked Sam.

"Yes, there they are!" shouted Tom, and pointed to the street beyond the dock.

"I see them," returned Dick. "Come on!" And he started for the street, as swiftly as his feet could carry him.
