When all hope of reaching the shore against such a wind was gone, he still struggled to keep the dory within hailing distance of the yacht, when it should come beating up from the northeast. But no yacht hove in sight; and if it passed, it must have been under the shadow of the shore. Clouds closed again over the one bright star and the patch of silver light in the west. The utter desolation of night lay about him on the lonely, weltering waters. All along the coast now he could see occasional lights--the lights in happy dwellings; but on the seaward side, only a faint gleam showed the line where sky and ocean met. There were no sounds but the ceaseless turmoil of the billows, the frequent slapping of a wave under the flat-bottomed boat, and his own fitful sobs. His last hope lay in crossing the track of some coaster or fishing-craft that might pick him up. But could that occur before morning? And could he expect that his ill-managed dory would ride safely all night on the increasing waves? The strong wind off shore, meeting the ocean swells, was blowing up a heavy chop-sea that threatened a new danger. What a night was before him, at the best! Suddenly his hat blew off, and disappeared immediately on the black waves. The distant sails he had seen at first had vanished as the swift night shut down; but now he discerned two dim lights in different directions, evidently far away. He was gazing after them, and looking anxiously for nearer lights or sails, when he was aware of a low, dark object just before him, rising from the deep. What could it be?--with something white flashing upon it! And what was the sound he heard? "The Cow and Calf!" he exclaimed, with sudden excitement, almost as if he had seen a friend. CHAPTER VIII. THE COW AND CALF. "The Old Cow" and "The Calf" are two enormous ledges lying not far asunder, within sight from the coast in clear weather. "The Cow" is never completely submerged; her bare brown back appears above the highest tides. "The Calf" is not so fortunate; the sea must be very calm at high water, when it is not buried in the surf. Near one end of it, to mark the position of the dangerous reef, a pole is anchored, rising out of the water with a slant that has gained for it the name of "The Calf's Tail." Often at high tide the tail only can be seen sticking out of the sea. What Olly saw and heard was the billows combing over the end of one of those huge rocks. He wondered why he hadn't thought of them before; for it now occurred to him that if he could land on "The Old Cow," he might safely pass the night on her back, and be seen from the shore, or from some passing craft, in the morning. But which of the ledges was he approaching? Familiar as their forms were to him, seen from the shore, he could not in his strange position, in the night, and amid the dashing waves, decide whether he was coming upon "The Old Cow" or "The Calf."
