10 A.M.—To my red maple sugar camp. Found that, after a pint and a half had run from a single tube after 3 P. M. yesterday, it had frozen about a half an inch thick, and this morning a quarter of a pint more had run . . .

  I left home about ten and got back before twelve with two and three quarters pints of sap, in addition to the one and three quarters I found collected.

  I put in saleratus and a little milk while boiling, the former to neutralize the acid, and the latter to collect the impurities in a scum. After boiling it till I burned it a little, and my small quantity would not flow when cool, but was as hard as half-done candy, I put it on again, and in a minute it was softened and turned to sugar . . .

  Had a dispute with Father about the use of my making this sugar when I knew it could be done and might have bought sugar cheaper at Holden’s. He said it took me from my studies. I said I made it my study; I felt as if I had been to a university.
