In this travel account the visit is to the studio of "Mr. Tabor" but it is presumably a misspelling of "Taber":
I must not leave this part of my journey without a word on that for which this place bears a world-wide renown; I allude to photography. The first morning after my arrival, when I got up to take in my boots, I found outside my door two envelopes addressed to me, each containing a cabinet photograph of some evidently well-known actress, and a card requesting me to visit the studio of the sender. As I had already collected a large assortment of photographic views on my travels, I now determined to add to it a collection of portraits as specimens of the art in the States. I called at several studios to make purchases, and at each place a lovely specimen of art was gratuitously given, in addition to what I bought. I think, as I have before said, that the San Francisco portraits rank first in my collection. The photographers themselves were highly intellectual men, and I owe much to Mr. Tabor and Mr. Boyd, for many pleasant moments spent in their studios. The former took the trouble to send after me to New York a duplicate of a work of art that I had much admired in his collection.
