Guess why?
Is it because the trees inside have been felled?
Well, some say so, who know more than I.

But now go over the fence, and see how many of these plants you can find on the moor.
Oh, I think I know.

I am so often on the moor.
I think you would find more kinds outside than you fancy.

But what do you know?
That beside some short fine grass about the cattle-paths, there are hardly any grasses on the moor save deer's hair and glade-grass; and all the rest is heath, and moss, and furze, and fern.
Softly--not all; you have forgotten the bog plants; and there are (as I said) many more plants beside on the moor than you fancy.

But we will look into that another time.
