Here, then, I tie my horse to this upright stone.

I must lay my silver groat here, and whistle three times, sayest thou ?" "Ay, but thou must whistle louder than an unfledged ousel," said the boy, as Tressilian, having laid down his money, and half ashamed of the folly he practised, made a careless whistle--"you must whistle louder than that, for who knows where the smith is that you call for?
He may be in the King of France's stables for what I know." "Why, you said but now he was no devil," replied Tressilian.
"Man or devil," said Dickie, "I see that I must summon him for you;" and therewithal he whistled sharp and shrill, with an acuteness of sound that almost thrilled through Tressilian's brain.

"That is what I call whistling," said he, after he had repeated the signal thrice; "and now to cover, to cover, or Whitefoot will not be shod this day." Tressilian, musing what the upshot of this mummery was to be, yet satisfied there was to be some serious result, by the confidence with which the boy had put himself in his power, suffered himself to be conducted to that side of the little thicket of gorse and brushwood which was farthest from the circle of stones, and there sat down; and as it occurred to him that, after all, this might be a trick for stealing his horse, he kept his hand on the boy's collar, determined to make him hostage for its safety.
"Now, hush and listen," said Dickie, in a low whisper; "you will soon hear the tack of a hammer that was never forged of earthly iron, for the stone it was made of was shot from the moon." And in effect Tressilian did immediately hear the light stroke of a hammer, as when a farrier is at work.

The singularity of such a sound, in so very lonely a place, made him involuntarily start; but looking at the boy, and discovering, by the arch malicious expression of his countenance, that the urchin saw and enjoyed his slight tremor, he became convinced that the whole was a concerted stratagem, and determined to know by whom, or for what purpose, the trick was played off.
Accordingly, he remained perfectly quiet all the time that the hammer continued to sound, being about the space usually employed in fixing a horse-shoe.

But the instant the sound ceased, Tressilian, instead of interposing the space of time which his guide had required, started up with his sword in his hand, ran round the thicket, and confronted a man in a farrier's leathern apron, but otherwise fantastically attired in a bear-skin dressed with the fur on, and a cap of the same, which almost hid the sooty and begrimed features of the wearer.
