“Yes,” said Cal; “it’s like leaving off when you find you’re talking too much. It’s hard to do.”

The little company tarried at the fort only long enough for the soldiers to make and fill six canvas sand bags. When they were afloat again and Dick had tested the bestowal of the ballast, he suggested that Tom should take his first lesson at the tiller. Sitting close beside him, the more expert youth directed him minutely until, after perhaps an hour of instruction, during which Dick so chose his courses as to give the novice both windward work and running to do, Tom could really make a fair showing in handling the sails and the rudder. He was still a trifle clumsy at the work and often somewhat unready and uncertain in his movements, but Dick pronounced him an apt scholar, and predicted his quick success in learning the art.

They were nearing the mouth of the harbor when Dick deemed it best to suspend the lesson and handle the boat himself. The wind had freshened still further, and a lumpy sea was coming in over the bar, so that while there was no danger to a boat properly handled, a little clumsiness might easily work mischief.

The boys were delighted with the behavior of the craft and were gleefully commenting on it when Larry observed that Tom, instead of bracing himself against the gunwale, was sitting limply on the bottom, with a face as white as the newly made sail.

“I say, boys, Tom’s seasick,” he called out. “We’d better put about and run in under the lee of Morris Island.”

“No, don’t,” answered Tom, feebly. “I’m not going to be a spoil-sport, and I’ll fight this thing out. If I could only throw up my boots, I’d be all right. I’m sure it’s my boots that sit so heavily on my stomach.”

“Good for you, Tom,” said Larry, “but we’ll run into stiller waters anyhow. We don’t want you to suffer. If you were rid of this, I’d—”

He hesitated, and didn’t finish his sentence.

“What is it you’d do if I weren’t playing the baby this way?”

“Oh, it’s all right.”
