"I have tried to give you a general view of ship-building, with a few of the more important technical terms, some of which most of you have learned before. As I have said, we shall not use all these pieces in building the boat. For example, a false keel is put under the true keel of a ship. It is a timber of the toughest wood, from four to six inches thick, which is bolted to the keel after the keelson is secured. It is but lightly fastened, for it is intended to come off, if the vessel strikes a shoal, and thus allow the true keel to slide off. We shall not need this addition, unless we require it to increase the depth of the keel. In that case, it would be better to have the part corresponding to the false keel made of lead or iron, and then it will serve as so much ballast. "On the table you see a wooden model of the boat we are to build. Its form and size are exactly indicated by the three plans I have explained. We are not ship-builders, only amateurs; and, while I shall take pains to have you understand the theory and practice of the art, I do not feel obliged to follow all the methods in use. So far as I know, no such model as the one on the table was ever made before. As I shall direct the construction of the boat, I shall do it in my own way, though it may not be according to the accepted rules. "I have kept you now longer than I intended, for, after the hard work you did last night, and the very quiet and business-like way in which you did it, I shall make the rest of the day a holiday. The Beech Hill fleet is at your service, and you may spend the day in any proper manner that you please. To-morrow afternoon we will dissect this model, and give out the work of building the boat. In the meantime I shall be glad to receive suggestions as to her name; but no student must send in more than one name, for I wish you to have decided opinions." CHAPTER XI. ROUGH WATER ON LAKE CHAMPLAIN. The wind was very fresh from the northwest on the lake, and its surface was covered with white-caps. Above Split Rock Point the lake looked like a sea of foam, and heavy waves rolled in upon the beach in Porter's Bay. Even Beechwater was considerably agitated. Prudent mothers would have thought it dangerous to go out upon the lake at such a time. Apparently for the reason that the water was rough on Lake Champlain, the students elected to have an excursion in the barges. The principal did not object, for the boys had been trained to rough weather, and they knew how to handle the boats in any sea that ever was stirred up on fresh water, albeit the waves are often more perilous on large lakes than on the ocean.
