Prints from positives can be made in two ways.  One is to make an
"internegative", and then print from this.  You could do this, for
example, by putting the slide on a light box and photographing it
on b&w print film.  Disadvantage: you're two generations removed from
the original (negative is one and print is two).

The second way is to use paper designed for printing from slides.
The glass slide is projected directly onto the paper using an enlarger.
The disadvantage here is that these kinds of papers are color-balanced
for particular slide emulsions (e.g. Ektachrome).  I have no idea what
kind of results you would get using a b&w positive.

U.S. copyright currently runs for the life of the author plus 50 years.

However, back when these views were taken, I believe the term was about
35 years, plus it could be renewed for a second 35 years.  In addition,
when the law was changed in the 1970's, a "grandfather" clause extended
the extra copyright to certain materials.  I don't have my copy of Title
17 here.  Let me stress that I am NOT A LAWYER and cannot give legal
advice.  It is my opinion that images from before the turn-of-the-century
are in the public domain.  I would consult with a U.S. copyright attorney
to be sure.
