TO GET ON A TOPMAST-CAP.--In vessels of the largest class, it may be necessary to send up the cap in the following manner, but it can usually be got up by hand. Or it may be fitted and the rigging put on over it. Send the cap up to the cross-trees by girt-lines, and place the round hole of the cap over the forward hole of the cross-trees; send aloft a topgallant studdingsail boom, and point its upper end through the holes in the cross-trees and cap, and lash the cap to it. Hook a tackle or girt-line to a strap on the lower end of the spar, and sway away until the cap is over the mast-head. Slue the spar so that the cap may come fair, lower away, and place the cap upon the mast-head. Unlash the spar and send it down. TO RIG OUT A JIB-BOOM.--Point the outer end through the collars of the stays. Reeve the heel-rope through a block at the bowsprit cap, through the sheave-hole at the heel of the boom, and secure the end to an eye-bolt in the cap on the opposite side. Rig the boom out until the inner sheave-hole is clear of the cap. Tar the boom-end, put on the foot-ropes and guys, and reeve the jib stay. Hoist up the martingale and rig it, and reeve the martingale stay and gaub-line. Rig the boom out to its place, and set up the jib and martingale stays. TO CROSS A LOWER YARD.--If the yard is alongside, reeve the yard rope through the jear block at the mast-head, make it fast to the slings of the yard, and stop it out to the yard-arm. Sway away, and cast off the stops as the yard comes over the side, and get the yard across the bulwarks. Lower yards are rigged now with iron trusses and quarter-blocks, which would be fitted before rigging the yard. Seize on the clew-garnet block, and put the rigging over the yard-arm; first the straps for the head-earings, then the foot-ropes, then the brace blocks or pennants, and last the eye of the lift. (The lifts, brace pennants, and foot-ropes are now spliced or hooked into rings with thimbles on an iron band, round the yard-arm, next the shoulders. In this way, there is no rope of any kind round the yard-arm.) Reeve the lifts and braces, get two large tackles from the mast-head to the quarters of the yard, and sway away on them and on the lifts, bearing off and sluing the yard by means of guys. Secure the yard by the iron trusses, and haul taut lifts and braces.
