was well known to Mr Rudyerd, however, that it was not possible to fit his timbers so perfectly to the rock and to each other as to exclude water altogether; and that if the water should manage to find entrance, it would exert a tremendous lifting power, which, coupled with the weight of the falling billows, would be apt to sweep his foundation away. He resolved, therefore, to counteract this by means of weight; and, in order to do this, he next piled five courses of Cornish moor-stone above the timber courses. The stones were huge blocks, which, when laid and fastened in one solid stratum, weighed 120 tons. They were not laid in cement; but each block was fastened to its fellow by joints and similar to the first. The whole of this fabric was built round a strong central mast or pole, which rose from the rock. The two timber courses above described terminated the “solid” part of the lighthouse. It rose to the height of about fourteen feet from the rock, at the centre of the building.
At this point in the structure; namely, at the top of the “solid,” the door was begun on the east side; and a central “well-hole” was left, where the stair leading to the rooms above was ultimately built. The door itself was reached by a strong iron stair of open work, outside, through which the sea could easily wash.
After the solid was completed, other five courses of moor-stone were laid, which weighed about eighty-six tons. It was in these that the door-way and well-hole were made. Two more courses of wood followed, covering the door-head; and on these, four more courses of stone, weighing sixty-seven tons; then several courses of timber, with a floor of oak plank, three inches thick, over all, forming the floor of the first apartment, which was the store-room. This first floor was thirty-three feet above the rock.
The upper part of the column, containing its four rooms, was by no means so strong as the lower part, being composed chiefly of the timber uprights in which the building was encased from top to bottom. These uprights, numbering seventy-one, were massive beams; about a foot broad and nine inches thick at the bottom, and diminishing towards the top. Their seams were caulked like those of a ship, and they gave to the lighthouse when finished the appearance of an elegant fluted column. The top of the column, on which rested the lantern, rose, when finished, to about sixty-three feet above the highest part of the rock.
We have thought proper to give these details in this place, but at the time of which we write, none of the outside timbers had been set up, and the edifice had only reached that point immediately above the “solid,” where the doorway and the “well-hole” began. Here a large crane had been fixed, and two of the men were up there working the windlass, by which the heavy blocks of moor-stone were raised to their places.
The signal had been given to hoist one of these, when Isaac Dorkin, who stood beside the stone, suddenly uttered a loud cry, and shouted, “hold on! Ease off up there! Hold o-o-on! D’ye hear?”
