Seven dollars a foot is not an unfair rule whereby to estimate the cost of a lap-streak, Nautilus model, including spars and rudder. Some builders charge more, others less than this. The Canadian canoes are cheapest of all, but to the first cost must be added the tariff duty for importation into the United States (about thirty per cent ad valorem). Herald's highest priced canoe, seventeen feet long, was at latest advices forty-five dollars. This size is built under his patent and copper fastened throughout. Built in the rib-batten style, the price is ten dollars less and canoes of smaller sizes of both kinds still less. The Nautilus models are largely decked over fore and aft without extra cost, and are provided with ample water-tight compartments which are invaluable in case of accident and may be fitted with hatches which render them available for stowage. The other models whose first cost is less, are not provided with these conveniences except by special arrangement, involving of course additional expense. A canoe may be purchased and fully rigged for less than a hundred dollars if her purchaser is gifted with mechanical ingenuity. Or if money is no object, the cost may be run up to almost any figure. The ordinary price of a double-bladed paddle is in the United States five dollars. All the builders make them. A specialist is Henry Mitchell, of Bergen, New Jersey. III. Miscellaneous. For sails use the best unbleached heavy twilled cotton sheeting, double width. Cut so that the selvedge will form the leach of the sail. Hem half an inch wide, stitched on both edges. Strong laid cotton cord about an eighth of an inch in diameter should be sewed along the luff of the sail, and is by no means undesirable along the other edges, loops for making fast being provided whenever needed. All these cotton articles should be well soaked before being made up to prevent unequal shrinkage. The plates entitled "Under full sail," and "Close hauled" give a sufficiently accurate idea of the size and shape of sails. The "Chrysalid," as drawn, is supposed to be fourteen feet long, and the "Red Laker" seventeen feet. From this the size of the sails can be easily ascertained. The flying jib shown in one of the cuts is of no practical use, and no one is advised to rig one. Laid or braided cotton cord of one-eighth-inch or a little more in diameter is best for running rigging. For painter use braided sash cord, or best Manilla hemp. Probably the best varnish for canoes, spars, paddles, etc., is "Pellucidite" Nos. 1 and 2, made by Seely and Stevens, of No. 32 Burling Slip, New York. The same house has "paste filling" which should be applied before the varnish. The best brown shellac is very good and possesses the inestimable virtue of drying in ten minutes. It may be applied over the paste filling above mentioned. All varnishes are better and clearer for being laid on and suffered to dry in the sun.
