Gentlemen: 
You may recall earlier correspondence with me 
in which, under date of May IQ, 1950, you were kind enough

Panama, and also a reference copy of the Esso Map of South 
America. 
I was in Panama again from February until

brief addition to the Panama road map in case you are

automobilists from the Canal Zone and from Panama City, 
both to reach various cottages built on the higher slopes and 
as a holiday drive. 
Cerro Campana is quite a prominent landmark 
from the highway, showing up as clearly as Cerro Trinidad 
which you show. It might be useful to include indication of the 
Cerro in which case you will be able to locate it from the 
standard maps of the area.

I have seen a later edition of this Esso Road Map 
of Panama last spring when I was in Balboa. If this is
