neatly, allowing space for windows on each side, as indicated. Leave the front open. Of the same kind of boards make your roof; the boards being light you can bend them down upon each side and nail them to the side roof-rods, forming a pretty curve, as may be seen in the illustration of the American boy's house-boat.

This Roof

to be finished neatly and made entirely water-proof, should be covered with tent-cloth or light canvas, smoothly stretched over and tacked upon the under side of the projecting edges. Three good coats of paint will make it water-proof and pleasant to look upon.

The description, so far, has been for a neatly finished craft, but I have seen very serviceable and comfortable house-boats built of rough lumber, in which case the curved roof, when they had one, had narrow strips nailed over the boards where they joined each other or was covered with tar-paper.

To Contrive a Movable Front

to your cabin, make two doors to fit and close the front opening, but in place of hanging the doors on hinges, set them in place. Each door should have a good strong strap nailed securely on the inside, for a handle, and a batten or cross-piece at top and bottom of inside surface. A 1½ by 4, run parallel to the front top cross-frame and nailed there, just a sufficient distance from it to allow the top of the door to be inserted between, will hold the top of the door securely. A two-by-four, with bolt-holes near either end to correspond with bolt-holes in the floor, will hold the bottom when the door is pushed in place, the movable bottom-piece shoved against it and the bolts thrust in (see [Fig. 225], view from inside of cabin. [Fig. 226], side view). It will be far less work to break in the side of the cabin than to burst in such doors, if they are well made. These doors possess this advantage: they can be removed and used as table-tops, leaving the whole front open to the summer breeze, or one may be removed, and still allow plenty of ventilation. A moulding on deck around the cabin is not necessary, but it will add finish and prevent the rain-water from leaking in.

To lock up the boat you must set the doors from the inside, and if you wish to leave the craft locked you must crawl out of the window and fasten the latter with a lock.
