For, away to the right of Byrsa Cottage, as you look down the hollow of the ground toward the sea, a ridge of high scrubby land runs up to a forefront of bold cliff, indented with a dark and narrow bay. “Goyle Bay,” as it is called, or sometimes “Basin Bay,” is a lonely and rugged place, and even dangerous for unwary visitors. For at low spring tides a deep hollow is left dry, rather more than a quarter of a mile across, strewn with kelp and oozy stones, among which may often be found pretty shells, weeds richly tinted and of subtle workmanship, stars, and flowers, and love-knots of the sea, and sometimes carnelians and crystals. But anybody making a collection here should be able to keep one eye upward and one down, or else in his pocket to have two things--a good watch and a trusty tide-table. John and Deborah Popplewell were accustomed to water in small supplies, such as that of a well, or a road-side pond, or their own old noble tan-pits; but to understand the sea it was too late in life, though it pleased them, and gave them fine appetites now to go down when it was perfectly calm, and a sailor assured them that the tide was mild. But even at such seasons they preferred to keep their distance, and called out frequently to one another. They looked upon their niece, from all she told them, as a creature almost amphibious; but still they were often uneasy about her, and would gladly have kept her well inland. She, however, laughed at any such idea; and their discipline was to let her have her own way. But now a thing happened which proved forever how much better old heads are than young ones. For Mary, being tired of the quiet places, and the strands where she knew every pebble, resolved to explore Goyle Bay at last, and she chose the worst possible time for it. The weather had been very fine and gentle, and the sea delightfully plausible, without a wave--tide after tide--bigger than the furrow of a two-horse plough; and the maid began to believe at last that there never were any storms just here. She had heard of the pretty things in Goyle Bay, which was difficult of access from the land, but she resolved to take opportunity of tide, and thus circumvent the position; she would rather have done it afoot, but her uncle and aunt made a point of her riding to the shore, regarding the pony as a safe companion, and sure refuge from the waves. And so, upon the morning of St. Michael, she compelled Lord Keppel, with an adverse mind, to turn a headland they had never turned before.
