On one side of the stick, range a line to represent the middle line of the mast; then apply the graduating batten at each quarter, and at the lower part of the spindle, with its end to the middle line, and take the half size of the spindle, which set off at the corresponding places, from the line representing the middle line at the side tree; and, at the same time, marking from the batten the diameters of the mast at the respective quarters and partners. This will give the form of the side tree, such as to conform to the spindle, and to the athwartship diameter of the mast. To line the fore and aft way, which is done after it has been sawn to the athwartship form, strike upon it the middle line as before, and mark, on the side upon which the middle line has been struck, the places of the quarters, partners, and end of the spindle, and transfer the size of these respective places from the spindle to the side tree, and strike lines through them; below the partners, or lower end of the spindle, the side trees are made parallel. It is very frequently the case, since the side trees are worked with the top end upwards, that the stick will not hold its breadth at the upper end; in which case pieces must be worked on its edges. In lining, therefore, hold a batten across the upper end, and range two lines to its size, here and at the partners; these lines will show the best manner of disposing of the piece on the edges, should it not be large enough, and strike it on as far down as the piece will hold, bringing the butts of the pieces under a hoop.
