“The outside must now be covered with pitched canvas, thus:—­

“Turn it upside down, in a sheltered spot exposed to the sun, or warm it by other means, and have a caldron of boiling pitch on a fire at hand, also have sufficient canvas sewn together in breadths as will quite cover the boat, bottom and sides; then, beginning across the middle of the bottom, brush on a layer 3 or 4 inches wide of the boiling pitch, and quickly press down the corresponding central portion of the canvas upon it; work on thus, from the centre of the bottom to the ends, laying on a breadth of pitch, and then pressing down and stretching a portion of canvas over it; then turn down the canvas over each side, and pitch in the same way, butting out the parts of the canvas that would overlap too much at the bends, but leaving no tin uncovered; the boat may then be righted, the excess of canvas cut off, and the edge laid down with pitch, a little short of the gunwale.

“The bottom may then be pitched over the canvas for 6 inches up, and the rest of the outside, with the inside, be painted with two or three coats.

“A flooring of thin planking for 3 1/2 feet of the central portion of the boat must now be made as follows:—­Make five planks, between 8 and 9 inches wide, to fit across the beam of the boat, and in each of the outer planks, o o, p p, fig.  III., fix uprights m n, 6 inches high, to support a seat, mortised on the pair of uprights in each board; the ends of each seat should be short of the breadth of the boat by an inch or so, so as not to bear against the sides; then lay down two ribs of tough wood, fitted to bear equally across the planking, on each side, as rs, r1 s1, and screw each end of them down to the outer planks only.

“Wooden cleats can be fixed on each board at t t, each to receive the butts of two guns, while their barrels lie in hollows formed in the cushions of the seat opposite them, so that the rower can put down his paddles and take up his gun instantly; steps for a mast can be also contrived at the same points.  The woodwork is to be also well painted; it can be taken out with ease, as it is nowhere connected with the tin of the boat.  Care should be taken that no projections in this woodwork, such as screw-heads, etc., should chafe the tin, and that it should be always kept well painted.

“The boat, of which this is a description, drew 2 1/2 inches water with one person in, with two guns and ammunition, etc.; it was furnished with two short paddles, which were tied by a short length of string to the sides, so as to be dropped without loss of time on taking up the gun to fire; the boat turned with the greatest ease, by one backing and pulling stroke of the two paddles, and was very stiff in the water.
