In plain English--go home and make a little Hartford Bridge Flat in the stable-yard; and then ask Mrs.How if she will not make a glen in it like this glen here.

We will go home and try that.

We will make a great flat cake of clay, and put upon it a cap of sand; and then we will rain upon it out of a watering- pot; and see if Mrs.How does not begin soon to make a glen in the side of the heap, just like those on Hartford Bridge Flat.

I believe she will; and certainly, if she does, it will be a fresh proof that my guess is right.

And then we will see whether water will not make glens of a different shape than these, if it run over soils of a different kind.
