Q.—If you have a largo ship, just launched and lying in the river, the spars for shears floating alongside, how would you get them on board?
A.—Sling "skids" up and down the sides for the purpose of keeping the shear legs clear of the sides. Secure three or four small spars in a slanting direction from the bulwark, to ease the shears down on. The shears being brought alongside, with their small ends aft, are taken on board either by parbuckle, derrick, or shears. As it is difficult to get heavy spars over the ship's topgallant bulwark, without breaking it, the better plan seems to be to have a pair of small shears forward with two tackles on the head of them, and to get the spars intended for shears in over the bows.
Q.—Next proceed to rig a pair of shears to take your masts in?
A.—Place their heads or after ends either on the taffrail, the break of the poop, or a spar placed in the most convenient spot, the more elevated the better. Square the heels exactly one with the other, so that when they come to be raised the legs may be found of equal height. Cross their heads, placing the shear head of the side on which the mast is coming in uppermost, and put on the head-lashing of new well-stretched rope, the lashing being at equal distances from the heels of both. After the lashing is on, the lower parts of the shears are drawn asunder, carrying one over to each gangway, and placing it on a solid piece of oak, or shoe, and lash them to the eye-bolts in the shoes; nail cleats on the heel of the shears to prevent the lashing slipping down. Clap stout tackles on the heels, two on each, one leading forward the other aft; set taut the after ones and belay them. Lash a three or four-fold block, as the upper one of the main purchase, over the first lashing (so that it will hang plumb under the cross), with canvas underneath to prevent chafing, passing the lashing round each shear head alternately; also, sufficiently long to secure the free action of the block. Lash the small purchase
