At last, after a night of the most wearisome watching, the day dawned, and the mists returned to their mountain fastnesses. Burning for a brush with the desperadoes, we towed the Dart out of her critical situation and got her under sail. The launch and cutter were ordered out, but here we were at fault. The morning sunlight slept calmly on the forest clad ridges and gray cliffs, and every irregularity and indentation of the shore were strongly shadowed forth; but not the least sign of harbor or anchorage could be seen, except under the rocky promontory we had just left, and every thing looked as forsaken and solitary as a creation's birth. However, not doubting that we should be able to sift the mystery, the boats put off, with full and well-armed crews, and on nearing the shore discovered a narrow inlet, that wound in between the two lofty cliffs, the one projecting out with a magnificent curve, so as entirely to conceal the channel until we approached within a few rods of the shore. "We've got on the right scent of the old fox now, I think," said Waters. "Speak low, gentlemen; if discovered we may meet with a reception here not altogether so agreeable--I don't like the appearance of those grave looking fellows, yonder," said Dacres, pointing to four cannon mounted on a low parapet, with their muzzles bearing directly toward us. "Why, the place is as silent as a grave-yard," muttered the old cockswain of the cutter. We advanced softly up the inlet, and found it to branch out into a broad basin. Here was explained the mystery of the Sea-Sprite's sudden disappearance; this was the _Pirate's Retreat_, and from their escaping hither and into similar resorts known only to themselves, arose the many wild stories that were abroad respecting their supernatural prowess. Fifty well armed men might have defended the place against five hundred assailants, as there was only one point, the inlet, susceptible of an attack. The entrance was not more than thirty feet in width--only sufficient for one vessel to enter at a time; but the water was bold and deep, with a sandy bottom. An enormous cavern yawned at the farther extremity of the basin, which Ponto immediately recognized as that where the pirates held their revel the previous night. But now the place was evidently deserted; the Sea-Sprite had made her escape.
