A year or two after this time, when Marco had been entirely cured of all such faults, he one day asked Forester to explain to him how he knew where he went on this memorable forenoon; and Forester willingly explained it to him. It seems that Forester's father, though a very gentle and kind-hearted man, was a very shrewd one, and having been accustomed to the discovery, in the course of his practice, of all sorts of pranks and roguery, was less disposed to place confidence in others till he knew the confidence was deserved, than Forester himself was, who had less experience. And when he knew that Forester had gone away, leaving Marco alone, he doubted a little whether he would remain industriously at his work. While he was thinking of this, he heard a slight noise which Marco made with his feet against the clapboards of the house in getting out the window. He therefore came into the study a moment afterward, and found that Marco had gone. He looked out the window and saw him going off toward the other boys. Just at that moment the man came to help him prune his trees, but before he began this work he went into the house to James, called him to a window and pointed out Marco to him, and said, "I want you, James, to follow him, and keep in sight of him until he returns, but if possible don't let him see you. Say nothing to me about it, but give my son Forester an account of all that you observe." James did as he was directed, and when Forester came back he told him the whole story, just before Forester went into the study. So that Forester knew all about it, before Marco saw him. James managed the affair very adroitly, for he kept himself entirely out of sight except in one instance, and that was when the boys fell into the water. He then rushed toward them for fear that they might be drowned, but he stopped on the bank when he saw that there was no danger, and disappeared again before Marco had time to recognize him. Chapter IX. Boating. The alterations and improvements, which Forester had ordered in the boat, were completed at the time promised. Marco said that it would require a crew of eight to man the boat properly: six oarsmen, a bowman, and a coxswain. Marco pronounced this word as if it was spelt _coxen_. This is the proper way to pronounce it. It means the one who sits in the stern, to steer the boat and direct the rowers. In fact, the coxswain is the commander of the boat's crew. "_I_ will be bowman," said Marco, "and you can be coxswain, and then we shall want six boys for oarsmen." "You will have to explain to me then what my duties will be," said Forester, "for I don't even know what a coxswain is." "Why, he's the commander," said Marco. "He gives all the orders."
