"Who said that I was afraid?" he retorted. "I was just taking note of where this passage stands on the hillside, so as to know it another time."

The stranger shrugged his shoulders. "Time enough to look for it when thou wouldst visit it again," he said. And then he pursued his way, with Dick following closely at his heels.

After the first yard or two they were enveloped in thick darkness, and the horse-dealer would have been sore put to it to keep near his guide had not the latter held out his hand for him to grasp. But after a little space a faint glimmering of light began to appear, which grew clearer and clearer, until at last they found themselves in an enormous cavern lit by flaming torches, which were stuck here and there in sconces in the rocky walls, and which, although they served to give light enough to see by, yet threw such ghostly shadows on the floor that they only seemed to intensify the gloom that hung over the vast apartment.

And the curious thing about this mysterious cave was that, along one side of it, ran a long row of horse stalls, just like what one would find in a stable, and in each stall stood a coal-black charger, saddled and bridled, as if ready for the fray; and on the straw, by every horse's side, lay the gallant figure of a knight, clad from head to foot in coal-black armour, with a drawn sword in his mailed hand.

But not a horse moved, not a chain rattled. Knights and steeds alike were silent and motionless, looking exactly as if some strange enchantment had been thrown over them, and they had been suddenly turned into black marble.

There was something so awesome in the still, cold figures and in the unearthly silence that brooded over everything that Canonbie Dick, reckless and daring though he was, felt his courage waning and his knees beginning to shake under him.

In spite of these feelings, however, he followed the old man up the hall to the far end of it, where there was a table of ancient workmanship, on which was placed a glittering sword and a curiously wrought hunting-horn.

When they reached this table the stranger turned to him, and said, with great dignity, "Thou hast heard, good man, of Thomas of Ercildoune—Thomas the Rhymer, as men call him—he who went to dwell for a time with the Queen of Fairy-land, and from her received the Gifts of Truth and Prophecy?"

Canonbie Dick nodded; for as the wonderful Soothsayer's name fell on his ears, his heart sank within him and his tongue seemed to cleave to the roof of his mouth. If he had been brought there to parley with Thomas the Rhymer, then had he laid himself open to all the eldrich Powers of Darkness.

"I that speak to thee am he," went on the white-haired stranger. "And I have permitted thee thus to have thy desire and follow me hither in order that I may try of what stuff thou art made. Before thee lies a Horn and a Sword. He that will sound the one, or draw the other, shall, if his courage fail not, be King over the whole of Britain. I, Thomas the Rhymer, have spoken it, and, as thou knowest, my tongue cannot lie. But list ye, the outcome of it all depends on thy bravery; and it will be a light task, or a heavy, according as thou layest hand on Sword or Horn first."
