If the halyards are not single, the yard must be sent down by a yard-rope, like the topgallant yard. In some vessels, instead of making the sheets and clewlines fast to the jack, overhand knots are taken in their ends, and they are let go. The sheets will run out to the topgallant yard-arms, and the clewlines will run to the fair-leaders in the cross-trees. In port, the main royal yard is sent down on the starboard side, and the fore and mizzen on the larboard; but at sea, the tye is stopped out on the lee side, and the yard sent down in any way that is the most convenient. TO SEND DOWN A TOPGALLANT YARD.--Cast off the sheets, bowlines, buntlines and clewlines, and make them fast to the cross-trees. Reeve a yard-rope through a jack-block at the mast-head, unhook the tye, cast off the parral-lashing, bend the yard-rope to the slings of the yard by a fisherman's bend, and stop it to the quarters of the yard. Sway away, and take off the lifts and braces, as with the royal yard. TO SEND DOWN A TOPGALLANT MAST.--Hook the top-block to the eye-bolt at the larboard side of the topmast cap; reeve the mast-rope through it, then through the sheave-hole in the foot of the topgallant mast, and hitch its end to the eye-bolt on the starboard side of the cap. Come up the rigging, stays and backstays, and guy the mast-head by them. Hoist a little on the mast-rope, and take out the fid. (The fid should always be fastened to the cross-trees or trestle-trees, by a lanyard.) Lower away until the mast is a little short of being through the cap. Then seize or rack together both parts of the mast-rope just above the sheave-hole; cast off the end of the mast-rope, letting the mast hang by the stops, and hitch it round the mast-head to its own part, below the cap. Then lower away to the deck. If the rigging is to come on deck, round up the mast-rope for a girtline; if it is to remain aloft, lash it to the topmast cap, render the shrouds through the cross-trees, and stop them up and down the topgallant rigging. Sheep-shank the stays and backstays, and set them hand-taut. If the top-mast is also to be sent down, take off the topmast cap and send it on deck. TO HOUSE A TOPGALLANT MAST.--Proceed in the same manner, except that when the mast is low enough, belay the mast-rope, pass a heel-lashing through the fid-hole and round the topmast. TO SEND DOWN A TOPMAST.--Hook the top-block, reeve the mast-rope through it and through the sheave-hole in the foot of the mast, and hitch it to the staple at the other side of the cap. Lead the fall through a snatch-block, to the capstan. Sling the lower yard, if it is to remain aloft, and unshackle the trusses, if they are of iron. Come up the rigging, stays and backstays, weigh the mast, take out the fid, and lower away. If the rigging is to remain aloft, lash the cross-trees to the lower cap. The rigging should be stowed away snugly in the top, and the backstays be snaked up and down the lower rigging.
