At the outer end of the breakwater there is a lighthouse, with a single fixed red light, so that it cannot be mistaken for any other of the neighbouring lights. At the end of the south pier-head of Weymouth Harbour is also a single red fixed light; but it is far
away to the northward of the breakwater light, and cannot be seen at any great distance.
The Portland Breakwater is indeed a magnificent work. The plans were designed by Mr Rendel, and the estimated cost was six hundred thousand pounds. The first stone was laid by Prince Albert, in July, 1849. The whole length is nearly a mile and a half. It first runs out from the Isle of Portland for 1,800 feet, when it is finished by a circular head of solid masonry. Then, for about four hundred feet, there is an opening through which vessels may enter or run to sea in case of necessity. Then comes another circular head similar to the first, from which the principal part of the breakwater extends in the same straight line for about three hundred feet, and then curves round to the north for 5,400 feet. It was formed—in the first instance—by extending stages in the direction required, on which rails were laid down to support the stone-wagons pushed by locomotives to the outer end. The wagons, on reaching their destination, were tilted up, and the stone dropped down to the bottom. Thus the work was continued gradually until the outer end was reached. The stones after they were thrown down were placed in the required position by divers, who worked with crowbars. A dangerous employment it must have been. A man employed on the breakwater who accompanied us told us that on one occasion the air-pipe burst, and that, although the diver immediately gave the signal, when he was hauled up he was nearly dead. Another poor fellow did not answer the tug, which a man in a boat above gave every half-minute. When he was hauled in it was found that the water had run under the joints of his helmet and drowned him. There were five lines of rail laid down, each carrying trucks pushed by locomotives. We were told that 2,500 tons of stone were by this means dropped every day into the ocean; and though thus actively working, it was long before the artificial rock appeared above the surface.
Sometimes several weeks passed, load after load being dropped in, before the mass was of sufficient size to rise above the water. After having been left some time to consolidate, the summit was capped by blocks of hewn stone, rising from low-tide mark to many feet above that of high-water, so that the sea during the fiercest gale could not force its way over it. The piles to support the stage were what are called screw piles; they were ninety feet in length, and soaked in creosote to preserve them, the weight of each being about seven tons. One of the most curious operations was that of forcing the creosote into the piles. It was done by placing them in an iron cylinder one hundred feet in length, and six feet in diameter. Out of this the air was first pumped, and then the creosote was pumped in.
All the stones were brought from the neighbouring hill, where they were quarried by about eight hundred convicts. The trucks descended from the hill down an incline, the full trucks dragging up the empties by means of ropes and blocks. Upwards of five million tons of stone were thus employed.
While visiting the prison we heard a number of anecdotes about the convicts. Notwithstanding all the vigilance of the warders and guards, several have contrived to make their escape. On a dark night, during exceedingly thick weather, a daring fellow managed to scale the walls and drop down outside unperceived. He at once made his way to the shore, where he in vain searched for a boat. Being no sailor, had he found one, he would have been unable to manage her. He knew that should he attempt to make his way overland he would, to a certainty, be re-taken. Finding a piece of wreck, with some broken oars, and other drift-wood, and a coil of rope, he contrived to put together a raft, on which seating himself, he shoved off, expecting to be picked up by some passing vessel. Instead of this, he was—fortunately for himself—discovered by the active coastguardmen, and brought back to prison. Had he succeeded in getting to a distance, in all probability he would have been drowned or starved to death.
Climbing to the top of the hill, we obtained a view to the northward of the crescent-shaped line of shingle, ten miles long, called Chesil Bank, which joins Portland to the main land. At the Portland end the pebbles are of the size of a hen’s egg, gradually diminishing to that of a bean at the other extremity. This enabled smugglers to ascertain on the darkest night the part of the shore they had reached. The west side of the bank is known as Dead Man’s Bay, from the number of persons who have perished there. The most disastrous event occurred in 1794, when a fleet of transports, under convoy of Admiral Christian, bound out for the West Indies, stranded in the bay, and one thousand persons were drowned. In this century, the Abergavenny and Alexander (Indiamen) were driven on this treacherous shore, and upwards of two hundred persons perished; and as late as 1838, the Columbine was wrecked on the bank, and many of her crew lost. In those days there were no lifeboats to hasten to the rescue of the helpless seamen.
Passing amid quarries, we observed enormous square blocks of stone hewn out and ready to be transported to the shore by carts, with long teams of horses harnessed—often nine together. In the upper layer of the quarries was discovered a fossil pine-tree, upwards of thirty feet in length, and a foot in diameter, with two or three branches.
Next morning we and the Dolphin again got under weigh, and the wind being off shore stood close round the Bill of Portland, having the Shambles light-vessel, which has a single fixed light, on our port beam. The Shambles is a large shoal, so called from the number of vessels lost on it with all hands. A fine Indiaman was wrecked there many years ago, coming home full of passengers, not one of whom was saved. In another day they expected to be reunited to their friends, from whom they had long been absent. How sad it seems! We who were sailing over the comparatively tranquil sea could scarcely believe it possible that so many of our fellow-creatures had thus perished within sight of land.
