As the tug and sloop passed into the broad water, Medford Village could be seen toward the southeast. Sanford adjusted his marine-glass, and focused its lens on Mrs. Leroy’s country-house. It lay near the water, and was surmounted by a cupola he had often occupied as a lookout when he had been Mrs. Leroy’s guest, and the weather had been too rough for him to land at the Ledge. He saw that the bricklayers were really at work, and that the dining-room extension was already well under way, the scaffolding being above the roof. He meant, if the weather permitted, to stop there on his way home.
Soon the Ledge itself loomed up. The concrete men were evidently busy, for the white steam from the mixers rose straight into the still air.
An hour more and the windows on the lee side of the shanty could be distinguished, and a little later, the men on the platform as they gathered to await the approaching flotilla. When they caught sight of the big blocks stored on the Screamer’s deck, they broke into a cheer that was followed by a shrill saluting whistle from the big hoisting-engine on the Ledge, answered as cheerily by the approaching tug. Work on the Ledge could now begin in earnest.
If Crotch Island was like the back of a motionless whale, Shark’s Ledge was like that of a turtle,—a turtle say one hundred and fifty feet long by a hundred wide, lying in a moving sea, and always fringed by a ruffling of surf curls, or swept by great waves that rolled in from Montauk. No landing could ever be made here except in the eddy formed by the turtle itself, and then only in the stillest weather.
The shell of this rock-incrusted turtle had been formed by dumping on the original Ledge, and completely covering it, thousands of tons of rough stone, each piece as big as a cart-body. Upon this stony shell, which rose above high-water mark, a wooden platform had been erected for the proper storage of gravel, sand, barrels of cement, hoisting-engines, concrete mixers, tools, and a shanty for the men. It was down by the turtle’s side—down below the slop of the surf—that the big enrockment blocks were to be placed, one on the other, their sides touching close as those on a street pavement. The lowest stone of all was to be laid on the bottom of the sea in thirty feet of water; the top one was to be placed where its upper edges would be thrust above its splash. In this way the loose rough stones of the turtle’s shell would have an even covering and the finished structure be protected from the crush of floating ice and the fury of winter gales.
By a change of plan the year before, a deep hole nearly sixty feet in diameter had been made in the back of this turtle by lifting out these rough stones. This hole was now being filled with concrete up to low-water level and retained in form by circular iron bands. On top of this enormous artificial bedstone was to be placed the tower of the lighthouse itself, constructed of dressed stone, many of the single pieces to be larger than those now on the Screamer’s deck. The four great derrick-masts with “twenty-inch butts” which had been ordered by telegraph the day before in Sanford’s office were to be used to place these dressed stones in position.
The situation was more than usually exposed. The nearest land to the Ledge was Crotch Island, two miles away, while to the east stretched the wide sea, hungry for fresh victims, and losing no chance to worst the men on the Ledge. For two years it had fought the captain and his men without avail. The Old Man of the Sea hates the warning voice of the fog-horn and the cheery light in the tall tower—they rob him of his prey.
The tug continued on her course for half a mile, steered closer, the sloop following, and gained the eddy of the Ledge out of the racing tide. Four men from the platform now sprang into a whaleboat and pulled out to meet the sloop, carrying one end of a heavy hawser which was being paid out by the men on the Ledge. The hawser was made fast to the sloop’s cleats and hauled tight. The tug was cast loose and sent back to Keyport. Outboard hawsers were run by the crew of the whaleboat to the floating anchor-buoys, to keep the sloop off the stone-pile when the enrockment blocks were being swung clear of her sides.
Caleb and Lacey began at once to overhaul the diving-gear. The air-pump was set close to the sloop’s rail; and a short ladder was lashed to her side, to enable the diver to reach the water easily. The air-hose and life-lines were then uncoiled.
Caleb threw off his coat and trousers, that he might move the more freely in his diving-dress, and with Lonny Bowles’s assistance twisted himself into his rubber suit,—body, arms, and legs being made of one piece of air-tight and water-tight rubber cloth.
