Adaline mentioned quite a few places they saw in Rochester. Here is some further information and a few photos. Some of the pictures are from ten or so years after she went through, so things might have looked a little different but it still gives a good idea of the city at that time:
Portsmouth Terrace Now this street is in The Neighborhood of the Arts
Information on Vick the seed man
Sibley, Lindsay and Curr Company The building Adaline saw burned down in 1904 and was then rebuilt. I could find no pictures of the building before the fire, although there are a couple of pictures of the building as it was burning.
