Friday, July 17, 1936

plesant and cool
Ironed the starch clothes this afternoon-
hoes part of the tomatoes and sprayed five rows of potatoes with arsenate of lead*
used all I had-
Aunty knocked the bugs off the rest.
We have not seen anyone but each other all day.

*Lead arsenate, or lead hydrogen arsenate, was a popular inorganic insecticide made by farmers by mixing soluable lead salts & sodium arsenate (Yes, that is arsenic folks). Irene & Aunty were most likely using it to kill potato beetles.
