center of shaft, as shown to diagonal 11, and the other making a like intersection with the curves of the slope, as shown on the diagram. These diagonals may now be lifted off and run in the

usual way on half-breadth, faired up, and retransferred to body plan, thus permitting of same being more accurately delineated, as it will be remembered these were originally drawn freehand.

Level lines as shown at la, la, ls, etc., are now drawn from the point of intersection of frame with diagonals 1 and 2, and the half-breadths taken off at these levels and finally faired-up on half-breadth, when it will be found that the resulting horizontal ribband line, besides acting as a check on the fairness of the diagonals, will show the wind " of the shell plating wrapping into oxter and body post and insuring a natural “snye " without any chance of gather " or unfairness.

The oxter underneath the ship's counter may be faired in a similar manner.
