In America the people are absolutely wiser and know much more than their grandfathers did.

They do not plow with a sharpened stick, nor yet with a three-cornered block of wood that merely scratches the top of the ground.

We do that because our fathers did, three thousand years ago, I suppose.

But those people have no holy reverence for their ancestors.
They plow with a plow that is a sharp, curved blade of iron, and it cuts into the earth full five inches.

And this is not all.
