Having fixed on the upper side of the main rail at the stern, continue the bag or upper side of its level with the beak head, as far out as possible, for the con veniency of the gratings, gradually ris ing the foremost end nearly parallel with the flight of the upper cheek, terminat ing the foremost end into the scroll of the hair bracket ; to complete the after end, describe the arch of a circle, that shall break in fair with the fore side of the beak head at the forecastle, and its upper side at the stem: the tinder side of the main rail is drawn by regularly taper ing it from 12 inches, its moulding at the forecastle, to 7 inches, its moulding at the fore end ; then continue the head of the main rail 2 feet 6 inches above the plank sheer, corresponding with the fore side of the beak head, and it is com plete.
The stations of the head timbers may next be drawn thus: place the stem tim ber, or that nearest the stem, which is 7 inches, sided half its siding before the stem, and parallel to it, from the upper side of the tipper cheek, to the under aide of the main rail; then fix the fare side of the foremost head timber on the upper side of the upper cheek well with the heel of the figure, raking it forward its aiding, which is 5 inches. The middle timber, which is sided 6 inches, may be now drawn exactly between the former two.
The two middle rails, between the main rail and upper cheek, may be next drawn, by dividing the distance equally between the latter at every head timber, curves then drawn, regularly tapering, as before, to their mouldings ; they may be thus represented, as far aft as the side, which terminates the after end of the low er rail, about two feet abaft the stem tim bers; and it may be now said, the rail above it also, as most ships now have the supporters under the cat-heads, to hang plumb, or nearly so; and although this may not finish quite so handsome as the rail continuing aft, and making the sup porter, yet it is much stronger for sup porting the cat-heads ; but we shall here describe its method of ending as has been usual, and the cat-head must be shown in the sheerplan ; and in order to do this, it must be first drawn in the half breadth plan; thus square down the aft side of the main rail, or beak head tim ber, from the sheer to the half breadth plan, squaring it across; and another line, 18 inches abaft it, which will be the fore side, and the latter, the after side of the cat-head, as upon the forecastle ; then from the intersection of the fore side of the cat-head, with the outside plank, at the top-timber, half breadth, or upper side of the forecastle, at the side, sweep a curve, at 9 feet distant, or without the bow ; for at this place the cat-head cuts the then square up a line that shall cut the arch last drawn, at 5 feet before the fore side of the cat-head; then a line drawn from its intersect ion, to where the fore side of the cat-head cuts the outside plank, shows what the cat-head casts for ward ; then a parallel line, drawn at 18 inches abaft it, on a square, will be the aft side, and to complete the cat-head on the half breadth plan, square the outer end. Now square upwards to the fore
castle on the sheer plan, where the aft side of the cat head cuts the outside plank on the half breadth plan, and like wise its outer ends; then level out a line where the cat-head cuts the upper side of the forecastle; at the aide above this line set up S feet 10 inches on the perpendi cular, squared up for the aft side at the outer end ; then from that spot draw a line to intersect the aft side of the cat head at the forecastle ; and that will be the under side of the cat-head, showing what it stives in its length upwards; then draw a parallel line above that to 16 inches, and the aft side of the cat-head will be shown ; then join the perpendicu lars at the outer end, agreeably to the sheer, and draw a line at the fore side, parallel to the aft side, and the under side of the cat-head will be represented. In the half breadth plan, draw the sup porter under the cat-head, what it is to project the bow, which is 6 feet 6 inches, and its siding 10 inches, placing it in the middle of the cat-head ; then square up its length and aft side to the under side of the cat-head, in the sheer plan, and draw a line parallel to the aft side of the cat head, from thence to the aide, its distance from the aft side of the cat-head. Then continue upwards the under side of the upper middle rail, with a curve parallel, or nearly so, to the aft side of the main rail ; then draw the outer end of the sup porter to the shape of a knee, and finish thereto the after end of the upper mid dle rail with a pleasing curve, resembling the after end of the main rail.
