If the wind freshened, he had a thousand chances to one of being swept helplessly out into the German Ocean; but the bold earl never thought of that.
Alone in the middle of the broad and rapid Firth, its aspect seemed to him magnificent, as the deep red light that lingered behind the western Ochills tinged all its waves with a purple hue; but their foam became a shower of silver, and white as winter frost, when it broke against the shining cliffs, whereon rose the castle at the west end of the island.
As the earl had resolved on freeing his mother and Sybil from their captivity, his natural boldness prevented him from seeing any difficulty in achieving this project, though he was alone in the enterprise, armed only with his poniard and an old sword which he had picked up in the brawl of the preceding night, and though the castle was commanded by Sir James Hamilton of Barncleugh, with a small but chosen party of soldiers.
"If a Seton could fear, I should certainly be afraid now," said the earl, on seeing how the waves burst in foam on all sides of the Inch—one moment sinking low, to show the reefs, which rose like jagged teeth above them, and the next dashing in torrents against the black volcanic bluffs. "Tut! by the pope! what a mouthful of salt-water!" he added, as the spray was blown in his face, when he dashed his boat through the breakers, and then, running along the lee of the shore, struck his sail and slowly crept near the little creek, which there forms the only landing-place; for on the east rushes the whole current of the Firth, and on the west breaks the thundering force of the German Sea.
The night had now come on, and solemn stillness reigned upon the isle.
The gates of the square tower which crowned its highest summit were closed; but here and there a red ray glimmered from the deep windows of its dusky mass.
"One of these lights," thought the earl, as he gazed upward, "may shine on my dear Sybil's dark glossy hair and snow-white brow."
The tide was low, and he ran the boat into a little cavern which lay near the creek; it was, in reality, but the top of a deep chasm in the rocks, having a clear sandy bottom, where he could distinctly perceive the layers of dark pebbles, of bright shells, and waving sea-weed, far down below, when the clear moon rose above the Lammermuir, to shed its radiance on the heaving water.
Resolving to wait till midnight, when all the inhabitants of the town most probably would be asleep, and when, with more security, he could make a reconnaissance of the isle and the barbican wall, the earl guided his boat into the narrow little fissure, which is one of many that perforate the island. While endeavouring to prevent its jarring on the flinty rocks, he was greatly alarmed by perceiving a human figure spring off a shelf of the volcanic wall, and plunge heavily into the deep dark water of the chasm, which penetrated, he knew not how far, into the heart of the island, but which, as it receded, became more appalling by its utter obscurity and subterranean character.
Incident to the age, rather than the man, the earl's supernatural fears of kelpies, gnomes, and water-spirits, now became altogether secondary to the dread of having been discovered by some human denizen of the place. He felt for his poniard, and paused. Behind him yawned the pointed arch of the cavern, with the distant sea-beach shining in the moonlight; before him lay rocks and water buried in darkness. He lingered, oar in hand, scarcely daring to breathe, but heard only the ripple of the rising tide as it chafed on the walls of the chasm.
