Dolly worked in the fields again yesterday, while I stayed in the air-cooled indoors doing computer work. Air coolers are combination of a fan, a water pump, and a wire cage lined with straw. The water is pumped to the top where it moistens the straw, and the fan blows in the cooler, wet air. It has been hot the past few days, so we have started using the coolers again.

Even though it was hot, Dolly went out to the fields of her own accord. I am surprised she likes the field work so much, as she would get tired biking for a mile to Harvard Square, and she doesn't generally like physical activity. However, she does like working with the other workers and the immediately visible results of a freshly weeded field.
