The Lighthouse Part 17

After a growl or two, and a few heavy sighs, they all tumbled out of their berths, and, in a very short time, were mustered on deck, where a gla.s.s of rum and a biscuit were served to each, being the regular allowance when they had to begin work before breakfast. Then they got into the boats and rowed away.

Ruby's troubles were peculiar on this occasion. He could not bear the thought of leaving the _Pharos_ without saying goodbye to Minnie; but as Minnie knew nothing of such early rising, there was no reasonable hope that she would be awake. Then he wished to put a few questions to his uncle which he had forgotten the day before, but his uncle was at that moment buried in profound repose, with his mouth wide open, and a trombone solo proceeding from his nose, which sadly troubled the unfortunates who lay near him.

As there was no way of escape from these difficulties, Ruby, like a wise man, made up his mind to cast them aside, so, after swallowing his allowance, he shouldered his big bellows, heaved a deep sigh, and took his place in one of the boats alongside.

The la.s.situde which strong men feel when obliged to rise before they have had enough of rest soon wears off. The two boats had not left the _Pharos_ twenty yards astern, when Joe Dumsby cried, "Ho! boys, let's have a race."

"Hooray!" shouted O'Connor, whose elastic spirits were always equal to anything, "an' sure Ruby will sing us `The girl we've left behind us.'

Och! an' there she is, av I'm not draymin'."

At that moment a little hand was waved from one of the ports of the floating light. Ruby at once waved his in reply, but as the attention of the men had been directed to the vessel by Ned's remark, each saw the salutation, and, claiming it as a compliment to himself, uttered a loud cheer, which terminated in a burst of laughter, caused by the sight of Ruby's half-angry, half-ashamed expression of face.

As the other boat had shot ahead, however, at the first mention of the word "race", the men forgot this incident in their anxiety to overtake their comrades. In a few seconds both boats were going at full speed, and they kept it up all the way to the rock.

While this was going on, the _Smeaton's_ boat was getting ready to take the strangers on board the sloop, and just as the workmen landed on the rock, the _Smeaton_ cast loose her sails, and proceeded to Arbroath.

There were a few seals basking on the Bell Rock this morning when the men landed. These at once made off, and were not again seen during the day.

At first, seals were numerous on the rock. Frequently from fifty to sixty of them were counted at one time, and they seemed for a good while unwilling to forsake their old quarters, but when the forge was set up they could stand it no longer. Some of the boldest ventured to sun themselves there occasionally, but when the clatter of the anvil and the wreaths of smoke became matters of daily occurrence, they forsook the rock finally, and sought the peace and quiet which man denied them there in other regions of the deep.

The building of the lighthouse was attended with difficulties at every step. As a short notice of some of these, and an account of the mode in which the great work was carried on, cannot fail to be interesting to all who admire those engineering works which exhibit prominently the triumph of mind over matter, we shall turn aside for a brief s.p.a.ce to consider this subject.

CHAPTER FOURTEEN.

SOMEWHAT STATISTICAL.

It has been already said that the Bell Rock rises only a few feet out of the sea at low tide. The foundation of the tower, sunk into the solid rock, was just three feet three inches above low water of the lowest spring-tides, so that the lighthouse may be said with propriety to be founded beneath the waves.

One great point that had to be determined at the commencement of the operations was the best method of landing the stones of the building, this being a delicate and difficult process, in consequence of the weight of the stones and their brittle nature, especially in those parts which were worked to a delicate edge or formed into angular points. As the loss of a single stone, too, would stop the progress of the work until another should be prepared at the workyard in Arbroath and sent off to the rock, it may easily be imagined that this matter of the landing was of the utmost importance, and that much consultation was held in regard to it.

It would seem that engineers, as well as doctors, are apt to differ.

Some suggested that each particular stone should be floated to the rock, with a cork buoy attached to it; while others proposed an air-tank, instead of the cork buoy. Others, again, proposed to sail over the rock at high water in a flat-bottomed vessel, and drop the stones one after another when over the spot they were intended to occupy. A few, still more eccentric and daring in their views, suggested that a huge cofferdam or vessel should be built on sh.o.r.e, and as much of the lighthouse built in this as would suffice to raise the building above the level of the highest tides; that then it should be floated off to its station on the rock, which should be previously prepared for its reception; that the cofferdam should be scuttled, and the ponderous ma.s.s of masonry, weighing perhaps 1000 tons, allowed to sink at once into its place!

All these plans, however, were rejected by Mr Stevenson, who resolved to carry the stones to the rock in boats constructed for the purpose.

These were named praam boats. The stones were therefore cut in conformity with exactly measured moulds in the workyard at Arbroath, and conveyed thence in the sloops already mentioned to the rock, where the vessels were anch.o.r.ed at a distance sufficient to enable them to clear it in case of drifting. The cargoes were then unloaded at the moorings, and laid on the decks of the praam boats, which conveyed them to the rock, where they were laid on small trucks, run along the temporary rails, to their positions, and built in at once.

Each stone of this building was treated with as much care and solicitude as if it were a living creature. After being carefully cut and curiously formed, and conveyed to the neighbourhood of the rock, it was hoisted out of the hold and laid on the vessel's deck, when it was handed over to the landing-master, whose duty it became to transfer it, by means of a combination of ropes and blocks, to the deck of the praam boat, and then deliver it at the rock.

As the sea was seldom calm during the building operations, and frequently in a state of great agitation, lowering the stones on the decks of the praam boats was a difficult matter.

In the act of working the apparatus, one man was placed at each of the guy-tackles. This man a.s.sisted also at the purchase-tackles for raising the stones; and one of the ablest and most active of the crew was appointed to hold on the end of the fall-tackle, which often required all his strength and his utmost agility in letting go, for the purpose of lowering the stone at the instant the word "lower" was given. In a rolling sea, much depended on the prompt.i.tude with which this part of the operation was performed. For the purpose of securing this, the man who held the tackle placed himself before the mast in a sitting, more frequently in a lying posture, with his feet stretched under the winch and ab.u.t.ting against the mast, as by this means he was enabled to exert his greatest strength.

The signal being given in the hold that the tackle was hooked to the stone and all ready, every man took his post, the stone was carefully, we might almost say tenderly, raised, and gradually got into position over the praam boat; the right moment was intently watched, and the word "lower" given sternly and sharply. The order was obeyed with exact prompt.i.tude, and the stone rested on the deck of the praam boat. Six blocks of granite having been thus placed on the boat's deck, she was rowed to a buoy, and moored near the rock until the proper time of the tide for taking her into one of the landing creeks.

We are thus particular in describing the details of this part of the work, in order that the reader may be enabled to form a correct estimate of what may be termed the minor difficulties of the undertaking.

The same care was bestowed upon the landing of every stone of the building; and it is worthy of record, that notwithstanding the difficulty of this process in such peculiar circ.u.mstances, not a single stone was lost, or even seriously damaged, during the whole course of the erection of the tower, which occupied four years in building, or rather, we should say, four _seasons_, for no work was or could be done during winter.

A description of the first entire course of the lower part of the tower, which was built solid, will be sufficient to give an idea of the general nature of the whole work.

This course or layer consisted of 123 blocks of stone, those in the interior being sandstone, while the outer casing was of granite. Each stone was fastened to its neighbour above, below, and around by means of dovetails, joggles, oaken trenails, and mortar. Each course was thus built from its centre to its circ.u.mference, and as all the courses from the foundation to a height of thirty feet were built in this way, the tower, up to that height, became a ma.s.s of solid stone, as strong and immovable as the Bell Rock itself. Above this, or thirty feet from the foundation, the entrance-door was placed, and the hollow part of the tower began.

Thus much, then, as to the tower itself, the upper part of which will be found described in a future chapter. In regard to the subsidiary works, the erection of the beacon house was in itself a work of considerable difficulty, requiring no common effort of engineering skill. The princ.i.p.al beams of this having been towed to the rock by the _Smeaton_, all the stanchions and other material for setting them up were landed, and the workmen set about erecting them as quickly as possible, for if a single day of bad weather should occur before the necessary fixtures could be made, the whole apparatus would be infallibly swept away.

The operation being, perhaps, the most important of the season, and one requiring to be done with the utmost expedition, all hands were, on the day in which its erection was begun, gathered on the rock, besides ten additional men engaged for the purpose, and as many of the seamen from the _Pharos_ and other vessels as could be spared. They amounted altogether to fifty-two in number.

About half-past eight o'clock in the morning a derrick, or mast, thirty feet high, was erected, and properly supported with guy-ropes for suspending the block for raising the first princ.i.p.al beam of the beacon, and a winch-machine was bolted down to the rock for working the purchase-tackle. The necessary blocks and tackle were likewise laid to hand and properly arranged. The men were severally allotted in squads to different stations; some were to bring the princ.i.p.al beams to hand, others were to work the tackles, while a third set had the charge of the iron stanchions, bolts, and wedges, so that the whole operation of raising the beams and fixing them to the rock might go forward in such a mariner that some provision might be made, in any stage of the work, for securing what had been accomplished, in case of an adverse change of weather.

The raising of the derrick was the signal for three hearty cheers, for this was a new era in the operations. Even that single spar, could it be preserved, would have been sufficient to have saved the workmen on that day when the _Smeaton_ broke adrift and left them in such peril.

This was all, however, that could be accomplished that tide. Next day, the great beams, each fifty feet long, and about sixteen inches square, were towed to the rock about seven in the morning, and the work immediately commenced, although they had gone there so much too early in the tide that the men had to work a considerable time up to their middle in water. Each beam was raised by the tackle affixed to the derrick, until the end of it could be placed or "stepped" into the hole which had been previously prepared for its reception; then two of the great iron stanchions or supports were set into their respective holes on each side of the beam, and a rope pa.s.sed round them to keep it from slipping, until it could be more permanently fixed.

This having been accomplished, the first beam became the means of raising the second, and when the first and second were fastened at the top, they formed a pair of shears by which the rest were more easily raised to their places. The heads of the beams were then fitted together and secured with ropes in a temporary manner, until the falling of the tide would permit the operations to be resumed.

Thus the work went on, each man labouring with all his might, until this important erection was completed.

The raising of the first beams took place on a Sunday. Indeed, during the progress of the works at the Bell Rock, the men were accustomed to work regularly on Sundays when possible; but it is right to say that it was not done in defiance of, or disregard to, G.o.d's command to cease from labour on the Sabbath day, but because of the urgent need of a lighthouse on a rock which, unlighted, would be certain to wreck numerous vessels and destroy many lives in time to come, as it had done in time past. Delay in this matter might cause death and disaster, therefore it was deemed right to carry on the work on Sundays. [See note 1.]

An accident happened during the raising of the last large beam of the beacon, which, although alarming, fortunately caused no damage.

Considering the nature of the work, it is amazing, and greatly to the credit of all engaged, that so few accidents occurred during the building of the lighthouse.

When they were in the act of hoisting the sixth and last log, and just about to cant it into its place, the iron hook of the princ.i.p.al purchase-block gave way, and the great beam, measuring fifty feet in length, fell upon the rock with a terrible crash; but although there were fifty-two men around the beacon at the time, not one was touched, and the beam itself received no damage worth mentioning.

Soon after the beacon had been set up, and partially secured to the rock, a severe gale sprang up, as if Ocean were impatient to test the handiwork of human engineers. Gales set in from the eastward, compelling the attending sloops to slip from their moorings, and run for the shelter of Arbroath and Saint Andrews, and raising a sea on the Bell Rock which was described as terrific, the spray rising more than thirty feet in the air above it.

In the midst of all this turmoil the beacon stood securely, and after the weather moderated, permitting the workmen once more to land, it was found that no damage had been done by the tremendous breaches of the sea over the rock.

That the power of the waves had indeed been very great, was evident from the effects observed on the rock itself, and on materials left there.

Ma.s.ses of rock upwards of a ton in weight had been cast up by the sea, and then, in their pa.s.sage over the Bell Rock, had made deep and indelible ruts. An anchor of a ton weight, which had been lost on one side of the rock, was found to have been washed up and _over_ it to the other side. Several large blocks of granite that had been landed and left on a ledge, were found to have been swept away like pebbles, and hurled into a hole at some distance; and the heavy hearth of the smith's forge, with the ponderous anvil, had been washed from their places of supposed security.

From the time of the setting up of the beacon a new era in the work began. Some of the men were now enabled to remain on the rock all day, working at the lighthouse when the tide was low, and betaking themselves to the beacon when it rose, and leaving it at night; for there was much to do before this beacon could be made the habitable abode which it finally became; but it required the strictest attention to the state of the weather, in case of their being overtaken with a gale, which might prevent the possibility of their being taken off the rock.

At last the beacon was so far advanced and secured that it was deemed capable of withstanding any gale that might blow. As yet it was a great ungainly pile of logs, iron stanchions, and bracing-chains, without anything that could afford shelter to man from winds or waves, but with a platform laid from its cross-beams at a considerable height above high-water mark.

The works on the rock were in this state, when two memorable circ.u.mstances occurred in the Bell Rock annals, to which we shall devote a separate chapter.

Note 1. It was always arranged, however, to have public worship on Sundays when practicable. And this arrangement was held to during the continuance of the work. Indeed, the manner in which Mr Stevenson writes in regard to the conclusion of the day's work at the beacon, which we have described, shows clearly that he felt himself to be acting in this matter in accordance with the spirit of our Saviour, who wrought many of His works of mercy on the Sabbath day. Mr Stevenson writes thus:--

"All hands having returned to their respective ships, they got a shift of dry clothes, and some refreshment. Being Sunday, they were afterwards convened by signal on board of the lighthouse yacht, when prayers were read, for every heart upon this occasion felt gladness, and every mind was disposed to be thankful for the happy and successful termination of the operations of this day."

It is right to add that the men, although requested, were not constrained to work on Sundays. They were at liberty to decline if they chose. A few conscientiously refused at first, but were afterwards convinced of the necessity of working on all opportunities that offered, and agreed to do so.
