In a few more seconds she had vanished. Rorke lowered the telescope and took a deep breath. Now he was safe. The boat had sunk unseen. But he was better than safe: he was free. His evil spirit, the standing menace of his life, was gone, and the wide world, the world of life, of action, of pleasure, called to him.
In a few minutes the fog lifted. The sun shone brightly on the red-funnelled cattle-boat whose whistle had startled him just now, the summer blue came back to sky and sea, and the land peeped once more over the edge of the horizon.
He went in, whistling cheerfully, and stopped the motor; returned to coil away the rope that he had thrown to Todd; and, when he had hoisted a signal for assistance, he went in once more to eat his solitary meal in peace and gladness.

“THE SINGING BONE”
(Related by Christopher Jervis, M.D.)
To every kind of scientific work a certain amount of manual labour naturally appertains, labour that cannot be performed by the scientist himself, since art is long but life is short. A chemical analysis involves a laborious “clean up” of apparatus and laboratory, for which the chemist has no time; the preparation of a skeleton—the maceration, bleaching, “assembling,” and riveting together of bones—must be carried out by some one whose time is not too precious. And so with other Scientific activities. Behind the man of science with his outfit of knowledge is the indispensable mechanic with his outfit of manual skill.
Thorndyke’s laboratory assistant, Polton, was a fine example of the latter type, deft, resourceful, ingenious and untiring. He was somewhat of an inventive genius, too; and it was one of his inventions that connected us with the singular case that I am about to record.
Though by trade a watchmaker, Polton was, by choice, an optician. Optical apparatus was the passion of his life; and when, one day, he produced for our inspection an improved prism for increasing the efficiency of gas-buoys, Thorndyke at once brought the invention to the notice of a friend at the Trinity House.
As a consequence, we three—Thorndyke, Polton and I—found ourselves early on a fine July morning making our way down Middle Temple Lane bound for the Temple Pier. A small oil-launch lay alongside the pontoon, and, as we made our appearance, a red-faced, white-whiskered gentleman stood up in the cockpit.
