Dear Fernald: 
I found Dodge had the Logan article already for me but I did not 
notice until I got back that the translation contained no information 
as to the date of Logan's trip. As I understand it Logan made his trip 
in 1844 and the publication came out in 1846. Is this correct? 
I was in such a hurry yesterday that I did not realize until I got 
away from the Uray Herbarium that you did not turn over to me the map 
that I sent you t with such corrections as you may want incorporated. 
If you don't get around to doing this before the next club meeting you 
can hand it to me at that time. If you have made corrections they may 
be of help in revising the map which I would like to do very soon. 
Of course, if you have no corrections on the map t lie re is no need of 
returning it. 
You may be interested in knowing that Dodge transcribed Logan's 
measurements, directions and distances on to a piece of wrapping paper 
on the same scale as my map and found, very much to my surprise , that 
the locations, brooks and distances checked ujj almost exactly with my 
map which was made without any knowledge or at least any detailed
