from them to make the modus operandi clear. The figures will be found on plate 19.
Figs. 1 and 2 have already been explained.
In breaking the rope one thing is to be observ'd, which will much facilitate the performance; and that is to place the iron eye L, (Fig. 3) thro' which the rope goes, in such a situation, that a plane going thro' its ring shall be parallel to the two parts of the rope; because then the rope will in a manner be jamm'd in it, and not slipping thro' it, the whole force of the man's action will be exerted on that part of the rope which is in the eye, which will make it break more easily than if more parts of the rope were acted upon. So the eye, tho' made round and smooth, may be said in some measure to cut the rope. And it is after this manner that one may break a whip cord, nay, a small jack-line with one's hand without hurting it; only by bringing one part of the rope to cut the other; that is, placing it so round one's left hand, that by a sudden jerk, the whole force exerted shall act on one point of the rope.
