This plan will replace the one that I mentioned in my letter of 
November 10 of going into La I alma which would wait until some other 
time. I may say that I had one reconnaissance flight over this region 
going from Chepo up the Bayano valley, crossing over to near the mouth 
of the Tuyra and then coming around along the coast to Chiman and up 
into the valley back of that village. This gave me a good view and 
some photographs of the lower levels, but unfortunately the higher 
mountains were in clouds as the flight took place on the first of May. 
I saw enough, however, to check with your data and to know that the 
more interesting area lies at the eastern end of the mountain range 
as Pico Coiumna appeared too rocky and was more barren. In this 
flight I am certain that I flew over the astrolabe station that you 
describe at the confluence of the Rios 3 abana and Lara. 
In 1944 I was located for a time on S a n Jose Island and have 
published a brief report on the birds of that Island and of Pedro 
Gonzalez, a copy of which 1 am pleased to send you herewith. 
If you have any further suggestions as to the country back of 
Chiman, I shall be very happy to have them. 
With appreciation of your attention, I am 
Very sincerely yours, 
A. Wetroore, 
Secretary.

will hold me in Washington until after the middle of February so that
