July 25, 1863: Murphys
[Today] I kept quiet all day, wrote up notes, observed barometer, got horses shod, etc. Professor Whitney is at the Big Trees and came down to see me; we discussed work and formed plans. We will get ready…Monday and the next day start on a new trip across the Sierra. I have lost over thirty pounds since I left the city, but feel in excellent health; the rheumatism induced by the cold and exposure is entirely gone here in this hot place.
Professor Whitney on his return had a sad greeting—three dear friends dead—one, a very dear sister, in San Francisco, Mrs. Putnam1, recently died, leaving six children, the eldest not fifteen, the youngest an infant of a few weeks—it is a most sad dispensation.
