The huge lake boat evidently was not carrying a load and its speed accordingly was unhampered. Doubtless the giant boat was returning to Duluth for another cargo of wheat or iron.

The progress was uninterrupted so that by the middle of the afternoon the high, rocky shores of Mackinac Island became visible in the distance.

At that moment the captain appeared at the stern of the lake boat and raising his megaphone to his mouth, called, “Do you want us to land you?”

“No,” replied Mr. Button also speaking through a megaphone, “we’ll find somebody that will take us in. If you’re not going to land there you needn’t stop on our account. How much do we owe you?”

“You don’t owe us anything,” called the captain. “We’re glad to lend a hand. Whenever you say the word you can cast off and we’ll haul in.”

A half-hour later Mr. Button announced through his megaphone that the time had arrived when there was no longer need for them to be towed. They could plainly see the yachts in the harbor and the people moving along the streets. To enter the harbor would compel the huge boat to change its course, an act which no one desired.

Accordingly after hailing the crew and expressing the thanks of himself and his companions for the aid they had received, Mr. Button gave the word and the little Gadabout was set free from the great steamer.

Another motor-boat near by, the occupants of which were deeply interested spectators of what was occurring, at once took the Gadabout in tow and noisily proceeded toward the wharf which was not more than two hundred yards away.

There were many questions asked of the rescued party, all of which were promptly answered, but as soon as the boys landed they at once began to make inquiries for a boat which could be chartered for a search for their missing friends.

At last, however, they listened to the persuasions of Mr. Button and went up to the hotel where they obtained a dinner, which satisfied them after their long fast.
