It was one mass of great sea-tangles like a grove, which prevented me judging of its nature, but in shape and size it bore some likeness to a vessel's hull. At least it was my best chance. If the ESPIRITO SANTO lay not there under the tangles, it lay nowhere at all in Sandag Bay; and I prepared to put the question to the proof, once and for all, and either go back to Aros a rich man or cured for ever of my dreams of wealth.
I stripped to the skin, and stood on the extreme margin with my hands clasped, irresolute. The bay at that time was utterly quiet; there was no sound but from a school of porpoises somewhere out of sight behind the point; yet a certain fear withheld me on the threshold of my venture. Sad sea-feelings, scraps of my uncle's superstitions, thoughts of the dead, of the grave, of the old broken ships, drifted through my mind. But the strong sun upon my shoulders warmed me to the heart, and I stooped forward and plunged into the sea.
It was all that I could do to catch a trail of the sea-tangle that grew so thickly on the terrace; but once so far anchored I secured myself by grasping a whole armful of these thick and slimy stalks, and, planting my feet against the edge, I looked around me. On all sides the clear sand stretched forth unbroken; it came to the foot of the rocks, scoured into the likeness of an alley in a garden by the action of the tides; and before me, for as far as I could see, nothing was visible but the same many-folded sand upon the sun- bright bottom of the bay. Yet the terrace to which I was then holding was as thick with strong sea-growths as a tuft of heather, and the cliff from which it bulged hung draped below the water-line with brown lianas. In this complexity of forms, all swaying together in the current, things were hard to be distinguished; and I was still uncertain whether my feet were pressed upon the natural rock or upon the timbers of the Armada treasure-ship, when the whole tuft of tangle came away in my hand, and in an instant I was on the surface, and the shores of the bay and the bright water swam before my eyes in a glory of crimson.
I clambered back upon the rocks, and threw the plant of tangle at my feet. Something at the same moment rang sharply, like a falling coin. I stooped, and there, sure enough, crusted with the red rust, there lay an iron shoe-buckle. The sight of this poor human relic thrilled me to the heart, but not with hope nor fear, only with a desolate melancholy. I held it in my hand, and the thought of its owner appeared before me like the presence of an actual man. His weather-beaten face, his sailor's hands, his sea-voice hoarse with singing at the capstan, the very foot that had once worn that buckle and trod so much along the swerving decks - the whole human fact of him, as a creature like myself, with hair and blood and seeing eyes, haunted me in that sunny, solitary place, not like a spectre, but like some friend whom I had basely injured. Was the great treasure ship indeed below there, with her guns and chain and treasure, as she had sailed from Spain; her decks a garden for the seaweed, her cabin a breeding place for fish, soundless but for the dredging water, motionless but for the waving of the tangle upon her battlements - that old, populous, sea-riding castle, now a reef in Sandag Bay? Or, as I thought it likelier, was this a waif from the disaster of the foreign brig - was this shoe-buckle bought but the other day and worn by a man of my own period in the world's history, hearing the same news from day to day, thinking the same thoughts, praying, perhaps, in the same temple with myself? However it was, I was assailed with dreary thoughts; my uncle's words, 'the dead are down there,' echoed in my ears; and though I determined to dive once more, it was with a strong repugnance that I stepped forward to the margin of the rocks.
A great change passed at that moment over the appearance of the bay. It was no more that clear, visible interior, like a house roofed with glass, where the green, submarine sunshine slept so stilly.
