"I'll tell you what we can do," exclaimed Harry. "Instead of rowing, let's tow the boat. One fellow can tow while another steers, and the rest can sleep in the boat."

"All right," said Joe. "I'm willing to be a mule. Only I'd like to know where my harness is coming from."

"We've got rope enough for that," replied Harry. "I'll take the first turn, and tow for an hour, while Joe steers; then I'll steer for an hour, while Joe tows. Then the other watch will take charge of the boat for two hours, and Joe and I will sleep."

"If I'm to sleep on the bottom of that boat," said Joe, "I want some nice sharp stones to sleep on. I'm tired of sleeping on coffee-pots, and want a change."

A long tow-line was soon rigged on Harry's shoulders in such a way that it did not chafe him; a space in the bottom of the boat was cleared of coffee-pots and other uncomfortable articles, and a pair of blankets was spread on the bottom board, so as to make a comfortable bed, which Tom and Jim hastened to occupy. Joe took the yoke-lines in his hand, and called to Harry to go ahead. When Harry first tugged at the tow-line, the boat seemed very heavy; but as soon as she was in motion, Harry found that he could tow her as fast as he could walk, and without any difficulty.

Had the locks been open and the canal-boats been out of the way, the experiment of towing the Whitewing at night would have been very successful. As it happened, the locks were kept closed during the night, because the water was low; and the canal-boats, not being able to pass the locks, were moored to the tow-path. These boats gave Harry and Joe a great deal of trouble. When one of them was met, Harry had to unharness himself and toss the rope into the boat, and Joe had to get out an oar and scull around the obstacle. This happened so often that Tom and Jim got very little sleep; and long before it was time for them to resume duty, a lock was reached, and Harry had to call all hands to drag the boat around it.

This was a hard piece of work. First, all the heavy things had to be taken out of the boat and carried around the lock. Then the boat had to be dragged out of the canal on to the tow-path, hauled up a steep ascent, and launched above the upper gate. It took a good half-hour to pass the first of these closed locks, and when the boat was again ready to start, it was time to change the watch.

Tom and Jim had managed to get only a few minutes' sleep, but Harry and Joe could not sleep a single wink. They had not "turned in" for more than ten minutes when another lock was reached. This involved a second half-hour of hard work by all hands, and twenty minutes later three more locks close together blocked the way. It was foolish to persevere in dragging the boat around locks all night long; so, after getting her out of the canal on the side opposite to the tow-path, the boys dragged her behind some bushes, where the canal boatmen could not see her at daylight. They then spread their rubber blankets on the ground, and prepared to sleep through the remaining four or five hours of darkness.

"Boys," said Joe, suddenly, "does it hurt a fat woman to jump on her?"

"Don't know," answered Harry. "What do you ask for?"
