"Shove her in!" Jim shouted. "I reckon Shanks hasn't made the meeting of the channels. We'll strike across the flat."

The sand was soft and they labored hard. When they were halt-way across, a low, dark object rose above the edge of the bank. It was roughly triangular and moving fast.

"Shanks's punt!" said Jake. "He has set the little black lugsail and the wind's fair. You can't head him off."

"I'm going to try," said Jim, who was now some yards in front; and they pushed on.

They were exhausted when they stopped beside a belt of sparkling water, and Jim cried out hoarsely and clenched his fist. The channel was wider than he had thought, and near the other bank a punt was running down with the tide. One could hardly see her low, gray hull, but the tanned lugsail cut sharply against the bank, and its slant and the splash of foam at the bows indicated speed. Shooting punts are not built to carry canvas, but they sail fast in smooth water when the wind is fair.

"We're too late; I don't know if I'm sorry," Jake remarked with labored breath. "My notion is, Shanks has pulled out for good, and nobody is going to miss him much. Wind's off the land, water's smooth, and the tide will run west for three or four hours. He'll be a long way down the coast before it turns. In the meantime, we're some distance from Langrigg and it looks as if you had lost your shoe."

"So I have!" said Jim. "Guess it came off when I was plowing through the mud. Well, let's get home. Shanks has gone and he'll find trouble waiting if he comes back."

They set off. Both were wet and dirty, and when they reached Langrigg Jim's foot was sore.
