Mr* Ratibor Hartmann, 
Avenlda Norte No. 16-A, 
Panama, R* de P. 
Dear Ratibor, 
I have waited to write you until I had some pictures that I 
could send as a souvenir of our work together in the eastern part of 
the province of Panama* 
After leaving you on our return to Balboa, Mr. Perrygo and 
I remained for a week longer in the Zone where I was fully occupied 
all the while in various necessary matters. Perry and I often spoke of 
you but did not have opportunity to look you up again. 
Perry had to remain until 1 came north myself since we 
could not get an earlier airplane reservation for him. 
Our specimens came through very promptly with everything in 
good shape. The big skins were still soft but thanks to the arsenic and 
alum and the preliminary drying that we had been able to give them,. 
there was no damage. I have the specimens all sorted now and identified 
to species ready for cataloging. The final count was 264 species with 
a number of additional subspecies represented* It is one of the finest 
collections that I have ever made in a similar length of time. Your own 
cheerful and competent assistance has been much appreciated. 
A day before I came north I went over to Chepo in a C-47 
with two excellent young pilots who flew me up the Rio Bayano, clear 
to the headwaters afad then around past the mouth of the Tuyra to Chimah, 
and then around the low mountains to the Bayano again and once more across 
to its headwaters. I thus have a very good idea of the lay of the land 
in that area and also have a number of photographs taken from the air. 
The mountains back of Chiman were in clouds so that I could not see the 
extreme summit. However, I could determine that the area is one of 
much interest. >’• 
The river valley itself is completely forested, wi. th very few 
clearings and these principally hot far above the mouth. I saw the 
Indian villages at about the center. I shall never be satisfied now 
until I have an opportunity to get into that country on the ground, and 
seriously planned already to make such a trip for the next dry season. 
The trip probably will have to be short as I do not expect that I will 
be able to be away for more than seven weeks or so from Washington.
