"I can't swim," he said. "At least, not much, you know."

"Well, who wants you to swim?" said Harry, laughing. "That's a pretty joke. Are you thinking of swimming across, and towing the boat after you? You can push her over easy enough; that pole will reach the bottom anywhere."

"Dat's so," said old Lewston. "It'll touch de bottom ob de water, but I don't know 'bout de bottom ob de mud. Ye musn't push her down too deep. Dar's 'bout as much mud as water out dar in de creek."

The more they talked about the matter, the greater became Harvey's disinclination to go over. He was not a coward, but he was not used to the water or the management of a boat, and the trip seemed much more difficult to him than it would have appeared to a boy accustomed to boating.

"I tell you what we'll do," cried Harry, at last. "You take my station, Harvey, and I'll go over and work your end of the line."

There was no opposition to this plan, and so Harry hurried off with Harvey to Lewston's cabin and helped him to make the connections and get the line in working order at that end, and then he ran down to the boat, jumped in, and Lewston pushed him off.

Harry poled the boat along quite easily through the shallow water, and when he got farther out he found that he proceeded with still greater ease, only he did not go straight across, but went a little too much down stream.

But he pushed out strongly toward the opposite shore, and soon reached the middle of the creek. Then he began to go down stream very fast indeed. Push and pole as he would, he seemed to have no control whatever over the boat. He had had no idea that the current would be so strong.

On he went, right down toward the bridge, and as the boat swept over it, one end struck an upright beam that projected above the water, and the clumsy craft was jerked around with such violence that Harry nearly tumbled into the creek.

He heard Lewston and Harvey shouting to him, but he paid no attention to them. He was working with all his strength to get the boat out of the current and into shallower water. But as he found that he was not able to do that, he made desperate efforts to stop the boat by thrusting his pole into the bottom. It was not easy to get the pole into the mud, the current was so strong; but he succeeded at last, by pushing it out in front of him, in forcing it into the bottom; and then, in a moment, it was jerked out of his hand, as the boat swept on, and, a second time, he came near tumbling overboard.
