It was not until Uncle John found that the water in the bays on the south side of Long Island, where Tom Schuyler wanted to cruise, was in nearly all places too shallow for drowning purposes, that he consented to say that he would "think about" the sail-boat plan. He thought about it for some time without seeing any good reason to approve of it. He told Tom that while it was true that the water in the bay was deep only in certain narrow steamboat channels, a sail-boat might capsize in one of these very channels. Besides, if one of the boys were to fall overboard, the sail-boat could not pick him up as quickly as he could be picked up were he to fall out of a row-boat. "After all," he added, "the real difficulty is that not one of you is accustomed to manage a sail-boat, and that is a difficulty which we can't get over." The boys still continued to talk among themselves about their desired cruise, without giving up the hope that Uncle John would change his mind, and when spring came something happened that did make him change it. Tom received a letter from his friend Charley Smith, who was in the Naval Academy at Annapolis, saying that he would come and spend the months of July and August with him. Now Charley was a very fine fellow, nearly a year older than Tom. He had been two years at the Academy, and was already a good sailor. Tom immediately wrote to him and asked him how he would like to be captain of a sail-boat, and go on a cruise through the south bays. Charley was delighted with the plan, and wrote to his guardian--for he had no father nor mother--and easily obtained his consent. Now Uncle John knew Charley Smith well, and thought very highly of him, and when Tom came to him and showed him Charley's letter, he said at once that the Department of Moral Piracy would be glad to put Captain Charles Smith in command of a cat-boat. "My dear boy," he continued, "I hated to say no when you proposed your plan, and I am as pleased as you are now that I can conscientiously approve of it. Charley is perfectly competent to manage a sail-boat, and if he will take charge of the boat, and you and the other boys will obey his orders, you shall have your cruise if I can bring it about." And he did bring it about, as Joe said he would. Mr. Sharpe, Mr. Schuyler, and Harry's father all gave their consent when Uncle John explained the matter to them; and when this important business was settled, Uncle John went with the boys to select a boat.
