of the block, and then from the stern; if you attempt to cut from end to
end, you will certainly split off too much. Finish this sheer line with
a spokeshave. The lines having been cut off the top of the block, draw
them again on your new surface, as well as the line X and the centre
line AB.

Now for Plate II. This gives the shape on deck. Using your compasses
again, take the distances from the line AB on the subdivisions from stem
to stern, and join with a curved rule, making the line HL. Before
cutting away the sides of the block, look at Plate IV.; this gives the
shape of the boat amidships. At the line X on deck it is but six inches
wide, but it gradually widens to seven inches. Cut away with a
draw-knife from 6 on the line MN to L, Plate II., and from 5 on MN to H,
striking the line HL at 8 in the former, and at 3 in the latter case.
The other side must be cut in the same way. The block had better be put
in a bench vise to do this. You have now your boat in the rough. With a
spokeshave round up the sides of the hull to HL. Turn your boat over,
and cut with a saw three and three-quarter inches from the left-hand
end, to a depth of three inches, and split off with a chisel.

Plate IV. gives the lines of the hull from the centre, to bow and stern.
Make careful and separate tracings of the curves marked from 1 to 10 and
X, paste on thin pieces of wood, cut them out with a knife or jig-saw,
and number them. Cut away the sides of the hull, testing with your
patterns at the respective subdivisions, and finish with a spokeshave.
Be careful near the stern-post of the swell where the shaft comes
through. In cutting the bow take the pattern of the curve BK, Plate I.,
and shape accordingly. Now you may begin to dig out the hull. Fit your
boat firmly to a table, or put it in a bench vise; but be careful not to
mar the sides. Allow half an inch inside of the deck line for the
thickness of the sides. Don't go too deep, but between the numbers 7 and
4 get the right depth or bed for your engine and boiler; place a
straight-edge across the boat at these points, and get just the depth;
the width necessary you will see in Plate V.

Plate II. For the deck use white pine one-eighth of an inch thick,
straight-grained, and free from knots. Follow the line DL in cutting the
deck. Allow the deck to project one-eighth of an inch all around; this
will ser
