"The process of building the paper shell-boat is as follows: The dimensions of the boat having been determined upon, the first step is to construct a wooden model, or form, an exact fac-simile of the desired boat, on which to mould the paper skin. For this purpose the lines of the boat are carefully drawn out of the full size, and from the drawings thus made the model is prepared. It is built of layers of well-seasoned pine, securely fastened together to form one solid mass; which, after having been laid up of the general outline required, is carefully worked off, until its surface, which is made perfectly smooth, exactly conforms to the selected lines, and its beam, depth, and length are those of the given boat. During the process of its construction, suitable rabbets are cut to receive the lower keelson, the two inwales, and the bow and stern deadwoods, which, being put in position, are worked off so that their surfaces are flush with that of the model, and forming, as it were, an integral part of it. It being important that these parts should, in the completed boat, be firmly attached to the skin, their surface is, at this part of the process, covered with a suitable adhesive preparation. "The model is now ready to be covered with paper. Two kinds are used: that made from the best Manila, and that prepared from pure unbleached linen stock; the sheets being the full length of the model, no matter what that may be. If Manila paper is used, the first sheet is dampened, laid smoothly on the model, and securely fastened in place by tacking it to certain rough strips attached to its upper face. Other sheets are now superposed on this and on each other, and suitably cemented together; the number depending upon the size of the boat and the stiffness required. If linen paper is used, but one sheet is employed, of such weight and dimensions that, when dry, it will give just the thickness of skin necessary. Should the surface of the model be concave in parts, as in the run of boats with square sterns for instance, the paper is made to conform to these surfaces by suitable convex moulds, which also hold the paper in place until, by drying, it has taken and will retain the desired form. The model, with its enveloping coat of paper, is now removed to the dry-room. As the paper skin dries, all wrinkles disappear, and it gradually assumes the desired shape. Finally, when all moisture has been evaporated, it is taken from the mould an exact fac-simile of the model desired, exceedingly stiff, perfectly symmetrical, and seamless.
