1764 August 16 (Thursday). Capt. Woods Pot-Ash at work. I was there to See it. Brewer the workman, to manage it. Messrs. Holbrook and Surcomb return and dine with me. At Eve I wait upon ‘em to Capt. Woods, they having never seen the working of Pot-ash. They were now smelting. These Gentlemen tarry with us over Night. N.B. Mr. Barns help me p.m. in gathering up my Oates.
