          Dr. S's object is to ascertain the comparative time of
the flowering of Trees & plants in the different parts 
of the Mississippi valey [Valley]. The Graminea are beginning to put 
forth their blossoms & soon the greater portion of the family
that are found in this region will [added: be] in that stage that
fits them for preservation. Texas is now in possession 
of the American population as far as the Rio Grande
& the emigration thither is very great. If I get the
proposed furlough I shall go west at least as far
as San Antonio. So extensive a region can only have
been imperfectly explored by Botanists whatever may 
have been their industry.

I remain
