"Mary," said her father again, "these are decent people, I'm thinking. Let you come from wherever you are, for I'm sure they wouldn't hurt yourself or myself."

As swiftly as she had disappeared she reappeared.

"I was looking if the ass was all right," said she sullenly.

She sat again by the brazier, and began to turn the potatoes with a stick. She did not appear to be taking any heed of the strangers, but it is likely that she was able to see them without looking, because, as is well known, women and birds are able to see without turning their heads, and that is indeed a necessary provision, for they are both surrounded by enemies.


CHAPTER III

The remarkable thing about astonishment is that it can only last for an instant. No person can be surprised for more than that time. You will come to terms with a ghost within two minutes of its appearance, and it had scarcely taken that time for Mac Cann and his daughter to become one with the visitors.

If the surprisor and the surprisee are mutually astonished, then, indeed, there is a tangle out of which anything may emerge, for two explanations are necessary at the one moment, and two explanations can no more hold the same position in time than two bodies can occupy the same lodgment in space.
