What kind of work did Lena do? Can you help?

After Charles died, Lena first worked at  The Geysers, a hotel-resort  in Sonoma County which advertised "the baths and mineral water water are a positive cure for stomach troubles and rheumatism.  And they had ELECTRICITY!  Here is a page from their booklet:

I believe Lena may have worked as a cook in The Geysers; at least when she left there in 1906 she applied as a cook for another place nearby and was told (via postcard from a friend) that the positing had already been taken.
So Lena took another job--I can't figure what it was. I am pretty sure it was at the Napa State Hospital for the Insane because many later postcard were addressed to her there, or referred to her work there.


Napa was known in the early 1900's for its winemaking industry, farming, the huge Napa State hospital, and brothels:"In the late 1800's and early 1900's Napa was known for having the largest red-light district for a California city of its size. In 1905, Napa had over twenty brothels^[5 primarily concentrated on and around Clinton Street. "

<sup>Here is a picture of that HUGE old hospital from around that time, from a postcard.


So here are some photos of Lena at work, with her coworkers, many of whom became her friends for life. I think that some of the photos, none of which have dates, may be from the Geysers and some from Napa)</sup>
