"I watched the sea all that day," said the clerk, "and I listened through the night; for it was heavy in my mind that the captain and first mate would return. For I knew the men who were in their boats,—hardy, desperate, unsparing men,—and I feared for my life."

"They did not return!" said the little apothecary. "Oh, no, I trust not! I dread to think otherwise."

"The drifting water took the hulk, weighted as it was," said Tom Horn; "with her forecastle down and her forward hatch almost under, the great circle took her and carried her away; and so the villains lost all track of her, and I drifted into the lonely sea. The sun shone through a haze," said the clerk; "its color was russet and streaked with white; so still was the air I saw spirals of mist, like ropes, lowered from the sky. On every side the sea was like a grassy field; I saw planks and spars lying on what seemed solid ground; great birds sat and watched me as though waiting for the time when I should die. There was a ghastly kind of vegetation: pallid, slimy plants,—bloodless,—like things that had grown in the dark; they were horrible to see and more horrible to touch. And," said Tom Horn, "a monstrous life stirred beneath the green scum of the sea. Since time began, God's hand has been turned to many dreadful tasks; but He has hidden them from most men's eyes."

"We will grant," said the girl, "that a ship, circumstanced as you believe the Rufus Stevens was at the end of the storm, must have fallen into the grasp of the great current and so came, or will come, to the Grassy Sea. But before going so far we must assure ourselves she remained afloat."

"Any one who watched her building," said Tom Horn, "must have seen she was a strong vessel. Siddons is an honest man; he never slights a task; he does honest, sound work. Live-oak is tough; hammered iron does not give readily; the ship was new, and, though the masts were out of her when Frisbee saw her, the decks were sound and the hatches fast down. I questioned him about that, and he was quite sure. The ship was like a cask," said Tom Horn. "The sea could not harm her, there being nothing to dash her against. Mark me! she is adrift at this moment in the slimy grass of that silent place; and her cargo is as dry and safe as it would be if it were in a merchant's storehouse."

Mademoiselle's hands trembled, but her voice was steady as she said:

"Would it be possible to find this strange ocean backwater? Could you—could any one—take a ship into it?"

"South of the Azores," said Tom Horn, "northwest of the Cape Verdes, and west of the Canaries." He nodded his head. "I could find my way back to it," said he. "Through all the vast spaces of the sea I could find my way back there, for it is so fixed in my mind that the very sky above it would be known to me if I once lifted it to the horizon-line."

"Anthony Stevens!" said mademoiselle to Christopher. "He must be told!"

"But his health!" protested the little apothecary.
