The Story of the Rock by R. M. Ballantyne (best ebook reader for surface pro .TXT) 📕

The incident referred to in our last chapter occurred on the afternoon of a calm summer day. Early that morning, shortly after daybreak, Mr Rudyerd, with his engineers and workmen, put off in the boat to resume operations on the rock after a lapse of nearly a week, during which period rough weather had stopped the work. They landed without difficulty, the calm being so complete that there was only a little sea caused by the heavy swell on the south-west side of the Eddystone Rock, the leeside being as quiet as a pond.

“It’s not often we have weather like this sir,” observed John Potter to Mr Rudyerd, as the heavily-laden boat approached the landing place.

“True, John; a few weeks like this would enable us almost to complete the courses,” replied the engineer. “Easy, lads, easy! If you run her up so fast you’ll stave in the planks. Stand by with the fender, Teddy!”

“Ay, ay, sir!” cried the man, springing up and seizing a stuffed canvas ball, which he swung over the gunwale just in time to prevent the boat’s side from grazing the rock. “There now: jump out wi’ the painter; man alive!” said Teddy, addressing himself to Isaac Dorkin, who was naturally slow in his movements, “you’ll go souse between the boat an’ the rock av ye don’t be smarter nor that.”

Dorkin made some grumbling reply as he stepped upon the rock, and fastened the painter to a ring-bolt. His comrades sprang after him, and while some began to heave the tools from the boat, others busied themselves round the base of the column, which had by that time risen to a considerable height. It looked massive enough to bid defiance to wind and waves, however fierce their fury. Some such thought must have passed through Mr Rudyerd’s mind just then, for a satisfied smile lighted up his usually grave features as he directed the men to arrange the tackle of the crane, by which the stones were to be removed from the boat to their place on the building. They were all quickly at work; for they knew from experience how suddenly their operations might be cut short by a gale.

In order that the reader may fully understand the details of the event which occurred that afternoon, it is necessary that he should know the nature of the structure, and the height to which, at that time, it had proceeded; and while we are on the subject, we may as well state a few facts connected with the foundation and superstructure, which cannot fail to interest all who take pleasure in contemplating man’s efforts to overcome almost insuperable difficulties.

As we have said, the sloping foundation of the building was cut into a series of terraces or steps. There were seven of these. The first operation was the cutting of thirty-six holes in the solid rock, into which iron hold-fasts were securely fixed. The cutting of these holes or sockets was ingeniously managed. First, three small holes were drilled into the rock; and then these were broken into one large hole, which was afterwards smoothed, enlarged, and undercut, so as to be of dovetail form; the size of each being 7 and a half inches broad and 2 and a half inches wide at the top, and an inch broader at the bottom. They were about sixteen inches deep. Thirty-six massive malleable iron hold-fasts were then inserted, and wedged into the places thus prepared for them, besides being filled up with lead, so that no force of any kind could draw them out. The next proceeding was to place beams of solid oak timber, lengthwise, on the first step, thus bringing it level with the second step. Timbers of the same kind were then placed above and across these, bringing the level up to the third step. The next “course” of timbers was again laid, lengthwise, bringing the level to the fourth step, and so on to the seventh, above which two completely circular timber courses were laid, thus making a perfectly flat and solid foundation on which the remainder of the column might rest. The building, therefore, had no tendency to slide, even although it had not been held in its place by the thirty-six hold-fasts before mentioned. In addition to this, the various courses of timber were fastened to the rock and to each other by means of numerous iron cramps and bolts, and wooden trenails.

It 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
