The next question is, what is the best time for seeing fairies? I believe I can tell you all about that.
The first rule is, that it must be a very hot day—that we may consider as settled; and you must be just a little sleepy—but not too sleepy to keep your eyes open, mind. Well, and you ought to feel a little—what one may call "fairyish"—the Scotch call it "eerie," and perhaps that's a prettier word; if you don't know what it means, I'm afraid I can hardly explain it; you must wait till you meet a fairy, and then you'll know.
And the last rule is, that the crickets shouldn't be chirping. I can't stop to explain that rule just now—you must take it on trust for the present.
So, if all these things happen together, you've a good chance of seeing a fairy—or at least a much better chance than if they didn't.
