What is it then?
It is because they are sketches of natur.

Natur in every grade and every variety of form; from the silver plate, and silver fork, to the finger and huntin' knife.

Our artificials Britishers laugh at; they are bad copies, that's a fact; I give them up.

Let them laugh, and be darned; but I stick to my natur, and I stump them to produce the like.
"Oh, Squire, if you ever sketch me, for goodness gracious sake, don't sketch me as an Attache to our embassy, with the Legation button, on the coat, and black Jube Japan in livery.

Don't do that; but paint me in my old waggon to Nova Scotier, with old Clay before me, you by my side, a segar in my mouth, and natur all round me.
