Everything round you is changing in shape daily and hourly, as you will find out the longer you live; and therefore it is most reasonable to suppose that this glen has changed its shape, as everything else on earth has done.
Besides, I told you not that Madam How had made the glen, but that she was making it, and as yet has only half finished.

That is my first guess; and my next guess is that water is making the glen--water, and nothing else.
You open your young eyes.

And I do not blame you.

I looked at this very glen for fifteen years before I made that guess; and I have looked at it some ten years since, to make sure that my guess held good.

For man after all is very blind, my dear boy, and very stupid, and cannot see what lies under his own feet all day long; and if Lady Why, and He whom Lady Why obeys, were not very patient and gentle with mankind, they would have perished off the face of the earth long ago, simply from their own stupidity.
