For the first six months he had thoroughly enjoyed his seclusion. In the company of his books, of which he had brought such a fair store that their shelves lined his snug corners to the exclusion of more comfortable furniture, he found his principal recreation. Even his unwonted manual labor, the trimming of his lamp and cleaning of his reflectors, and his personal housekeeping, in which his Indian help at times assisted, he found a novel and interesting occupation. For outdoor exercise, a ramble on the sands, a climb to the rocky upland, or a pull in the lighthouse boat, amply sufficed him. “Crank” as he was supposed to be, he was sane enough to guard against any of those early lapses into barbarism which marked the lives of some solitary gold-miners. His own taste, as well as the duty of his office, kept his person and habitation sweet and clean, and his habits regular. Even the little cultivated patch of ground on the lee side of the tower was symmetrical and well ordered. Thus the outward light of Captain Pomfrey shone forth over the wilderness of shore and wave, even like his beacon, whatever his inward illumination may have been. It was a bright summer morning, remarkable even in the monotonous excellence of the season, with a slight touch of warmth which the invincible Northwest Trades had not yet chilled. There was still a faint haze off the coast, as if last night's fog had been caught in the quick sunshine, and the shining sands were hot, but without the usual dazzling glare. A faint perfume from a quaint lilac-colored beach-flower, whose clustering heads dotted the sand like bits of blown spume, took the place of that smell of the sea which the odorless Pacific lacked. A few rocks, half a mile away, lifted themselves above the ebb tide at varying heights as they lay on the trough of the swell, were crested with foam by a striking surge, or cleanly erased in the full sweep of the sea. Beside, and partly upon one of the higher rocks, a singular object was moving. Pomfrey was interested but not startled. He had once or twice seen seals disporting on these rocks, and on one occasion a sea-lion,--an estray from the familiar rocks on the other side of the Golden Gate. But he ceased work in his garden patch, and coming to his house, exchanged his hoe for a telescope. When he got the mystery in focus he suddenly stopped and rubbed the object-glass with his handkerchief. But even when he applied the glass to his eye for a second time, he could scarcely believe his eyesight. For the object seemed to be a WOMAN, the lower part of her figure submerged in the sea, her long hair depending over her shoulders and waist. There was nothing in her attitude to suggest terror or that she was the victim of some accident. She moved slowly and complacently with the sea, and even--a more staggering suggestion--appeared to be combing out the strands of her long hair with her fingers. With her body half concealed she might have been a mermaid!
