gun to flow, the artificers were occupied in removing the forge from the top of the building, to which the gangway or wooden bridge gave great facility; and, although it stretched or had a span of forty-two feet, its construction was extremely simple, while the roadway was perfectly firm and steady. In returning from this visit to the rock every one was pretty well soused in spray before reaching the tender at two o'clock p.m., where things awaited the landing party in as comfortable a way as such a situation would admit. Friday, 11th May. The wind was still easterly, accompanied with rather a heavy swell of sea for the operations in hand. A landing was, however, made this morning, when the artificers were immediately employed in scraping the seaweed off the upper course of the building, in order to apply the moulds of the first course of the staircase, that the joggle-holes might be marked off in the upper course of the solid. This was also necessary previously to the writer's fixing the position of the entrance door, which was regulated chiefly by the appearance of the growth of the seaweed on the building, indicating the direction of the heaviest seas, on the opposite side of which the door was placed. The landing-master's crew succeeded in towing into the creek on the western side of the rock the praam-boat with the balance-crane, which had now been on board of the praam for five days. The several pieces of this machine, having been conveyed along the railways upon the waggons to a position immediately under the bridge, were elevated to its level, or thirty feet above the rock, in the following manner. A chain-tackle was suspended over a pulley from the cross-beam connecting the tops of the kingposts of the bridge, which was worked by a winch-machine with wheel, pinion, and barrel, round which last the chain was wound. This apparatus was placed on the beacon side of the bridge, at the distance of about twelve feet from the cross-beam and pulley in the middle of the bridge. Immediately under the cross-beam a hatch was formed in the roadway of the bridge, measuring seven feet in length and five feet in breadth, made to shut with folding boards like a double door, through which stones and other articles were raised; the folding doors were then let down, and the stone or load was gently lowered upon a waggon which was wheeled on railway trucks towards the lighthouse. In this manner the several castings of the bala
