This time Dan did not see Nelson as the latter came along the pier. He was standing near the edge, daring Hethington to go over with his hands clasped under his knees, and knew nothing of his danger until he found himself lifted from his feet. Then he struggled desperately, but Nelson had seized him from behind and his hands found no clutch on his captor’s wet body. The next instant he was falling over and over in a most undignified and far from scientific attitude. He tried to gather himself together as he struck the water, but the attempt was not a success, and he disappeared in a writhing heap. Like Nelson, he came up choking and gasping, trying his best to put a good face on it, but succeeding so ill that the howls of laughter that had greeted his disappearance burst forth afresh. But, thought Nelson, he was a wonderful chap to take a joke, for, having found his breath, he merely swam quickly to the steps and came up onto the pier looking as undisturbed as you please.

“That puts us even again, doesn’t it?” he said to Nelson.

Nelson nodded.

He kept a watch on Dan the rest of the time, but the latter made no attempt to trouble him again. He profited to some extent by Dr. Smith’s instructions, and when the cry of “All out!” came he believed that to-morrow he would have the courage to try a dive from the “crow’s-nest,” as the fellows called the little platform above the pier. He walked up the hill with Bob and Tom.

“I don’t see why that silly idiot of a Speede wants to be forever trying his fool jokes on me,” he said aggrievedly.

“That’s just his way,” answered Tom soothingly.

“Well, it’s a mighty tiresome way,” said Nelson, in disgust.

“He has an overdeveloped sense of humor,” said Bob Hethington. “It’s a sort of disease with him, I guess.”

“Well, I wish he’d forget it,” Nelson grumbled. “I’m afraid to sit down on a chair now for fear there’ll be a pin in it.”

“Oh, he gets tired after a while,” said Bob. “He was that way with me for a day after camp began.”
