And he might have been selling horses to him yet, for aught I know, had it not been for his one failing.

Canonbie Dick was apt to get very thirsty, and his ordinary customers, knowing this, took care always to provide him with something to drink. The old man never did so; he paid down his money and led away his horses, and there was an end of the matter.

But one night, Dick, being even more thirsty than usual, and feeling sure that his mysterious friend must live somewhere in the neighbourhood, seeing that he was always wandering about the hillside when everyone else was asleep, hinted that he would be very glad to go home with him and have a little refreshment.

"He would need to be a brave man who asks to go home with me," returned the stranger; "but, if thou wilt, thou canst follow me. Only, remember this—if thy courage fail thee at that which thou wilt behold, thou wilt rue it all thy life."

Canonbie Dick laughed long and loud. "My courage hath never failed me yet," he cried. "Beshrew me if I will let it fail now. So lead on, old man, and I will follow."

Without a word the stranger turned and began to ascend a narrow path which led to a curious hillock, which from its shape, was called by the country-folk the "Lucken Hare."

It was supposed to be a great haunt of Witches; and, as a rule, nobody passed that way after dark, if they could possibly help it.

Canonbie Dick was not afraid of Witches, however, so he followed his guide with a bold step up the hillside; but it must be confessed that he felt a little startled when he saw him turn down what seemed to be an entrance to a cavern, especially as he never remembered having seen any opening in the hillside there before.

He paused for a moment, looking round him in perplexity, wondering where he was being taken; and his conductor glanced at him scornfully.

"You can go back if you will," he said. "I warned thee thou wert going on a journey that would try thy courage to the uttermost." There was a jeering note in his voice that touched Dick's pride.
