Note, in Crisp's hand, written in pencil below the table:
Forty-one at six is not a Saturday night that ends in the press as I left it. The press door was open when I came down at half past five. The boiler was good and the night was mild — fifty-three at the kitchen door at eleven, by Aldred's own reading. There has been no draught the morning could account for. A door propped will drop the press fourteen degrees inside the half-hour and recover the same in three. I have looked at the door catch. The catch is not forced. The iron weight I prop with on hot days is in the gravel by the south wall. I did not put it there.
I have not entered this in my night reading because I did not take a night reading on the Saturday. I shall take one nightly from this date.
— A. Crisp, head gardener, 8th iv 1923.
