On the near point of the half-moon stood Keyport Light,—an old-fashioned factory chimney of a Light,—built of brick, but painted snow-white with a black cigar band around its middle, its top surmounted by a copper lantern. This flashed red and white at night, over a radius of twenty miles. Braced up against its base, for a better hold, was a little building hiding a great fog-horn, which on thick days and nights bellowed out its welcome to Keyport’s best. On the far point of the moon—the one opposite the Light, and some two miles away—stretched sea-meadows broken with clumps of rock and shelter-houses for cattle, and between these two points, almost athwart the mouth of the harbor, like a huge motionless whale lay Crotch Island, its backbone knotted with summer cottages. Beyond the island away out under the white glare of the risen sun could be seen a speck of purplish-gray fringed with bright splashes of spray glinting in the dazzling light. This was Shark’s Ledge. As Sanford looked toward the site of the new Light a strange sensation came over him. There lay the work on which his reputation would rest and by which he would hereafter be judged. Everything else he had so far accomplished was, he knew, but a preparation for this his greatest undertaking. Not only were the engineering problems involved new to his experience, but in his attitude in regard to them he had gone against all precedents as well as against the judgments of older heads, and had relied almost exclusively upon Captain Joe’s personal skill and pluck. While it was true that he never doubted his ultimate success, there always came a tugging at his heartstrings and a tightening of his throat whenever he looked toward the site of the lighthouse. Turning from the scene with a long drawn breath, he walked with slackened step down the slope that led to the long dock fronting the captain’s cottage. As he drew nearer he saw that the Screamer had been moored between the captain’s dock (always lumbered with paraphernalia required for sea-work) and the great granite-wharf, which was piled high with enormous cubes of stone, each as big as two pianos. On her forward deck was bolted a hoisting-engine, and thrust up through the hatch of the forecastle was the smoke-stack of the boiler, already puffing trial feathers of white steam into the morning air. She had, too, the heavy boom and stout mast used as a derrick. Captain Joe had evidently seen no reason to change his mind about her, for he was at the moment on her after-deck, overhauling a heavy coil of manilla rope, and reeving it in the block himself, the men standing by to catch the end of the line.
