“And now let us go; I lead—­you follow.”

“Forward, then,” responded Leo, rising from his lounging attitude.

The elf went nimbly down the corridor, as if accustomed to it, and paused before a door which led to a flight of stone steps.

“Are you going down cellar?” asked Leo, who knew where the stairs led.

“I am,” replied Knops; “but these huge doors and heavy hinges bother me.  Be so good as to open and close them for me.  By-the-way, you may get hungry; shall we find food down here?”

“Perhaps so,” said Leo, following, and doing as requested.

They went down step after step, and it was wonderful how much light came from that little blue flame.

On skipped the elf, his gown puffing out, his nailed boots pattering over the stones, and Leo found himself quite breathless when they reached the cellar, so unused was he to any rapidity of movement.

“Suppose we meet some one,” said Leo.

“And what have we to fear if we do?  No one can see me, and if you are afraid of a scullion or house-maid you are not the Prince I take you for.  Tut! tut! don’t be afraid—­come on.”

The cellar was damp, and great curtains of cobwebs, like gray lace, fell over the empty bins and wine-vaults.  From a heap of winter vegetables Leo filled his pockets with apples and turnips.

They came at last to a door which Leo remembered having opened once, but finding that it led to a passage which was dark, dismal, and unused, he had not cared to explore it.  He now followed the elf through it, but not without misgivings, for as he groped along he stepped on a round object which, to his horror when the little blue flame of the elf’s lantern revealed its empty sockets and grinning jaws, proved to be a skull.

Knops turned with a smile when he saw Leo’s agitation, and said, blandly,

“You are not interested in this form of natural history, I see.”  Then taking up the skull, he placed it in a crevice of the wall, saying, “Here is another proof that there are no ghosts about.  Do you think any one would be so careless of his knowledge-box as to leave it to be kicked around in that way?  Oh, those old monks were miserable house-keepers; the idea of stowing away their skeletons so near their kitchen closets!”

Leo smiled faintly, and went on after Knops, who every once in a while gave a tap on the walls with his tool, starting the echoes.

“There!” said he, “do you hear that?  This is the way we make old houses haunted.  I don’t do it for fun, as do the elves of folly.  I have a sensible purpose; but they like nothing better than to frighten people, and so they make these noises at all hours, and get up reports that a house is bewitched; but even a common insect like the cricket can do that, human beings are such ridiculous cowards.”

Leo made an effort to assume the courage which he did not feel, and asked his guide how much farther he intended to lead him.
