In the book of that title, the author describes how women cottagers would "wash down as far as possible, and up as far as possible" meaning that you wash one half of your body while the other half is still somewhat warmly clad, and then vice versa. The phrasing led the men to ask slyly about "poor Possible" and didn't it get a wash?

IIRC, it also describes a "Saturday bath" procedure in the boiler house with a copper washtub. Families sometimes reused the bath water, with the girls getting the first bath (quite hot, but clean water) and the dirtier boys using the same water (tepid and soapy). Another method was for the women to wash in the morning and the men to wash in the afternoon. So the boilerhouse was in use all day. I suppose the boiler was used for laundry the rest of the week.

Which reminds me to ask about the Great Wash in JA's letters. Is this the right point in the MT to inquire how it was managed?

P.S.(The time range described by the book covers only the latter part of the JA time period, I think.)
