From the minute description of the machinery, I am apt to think it is made at a considerable expense; … I am therefore induced to mention the manner of hummelling (or fattering, as it is called in this county) with me. … My thrashing mill is of the old construction, being the first erected in this county (excepting one on Cotterel's plan), and is very powerful; but I apprehend any machine has power enough for the hummelling work.
