Mr. S. J. Eckerson, 
General Drafting Company, 
21 West Street, 
New York 6, New York. 
Dear Mr. Eckerson: 
I appreciate yours of May 10 with the new map 
of Panama and also the reference map of South America 
enclosed. I note that you are revising the Panama 
map and enclose herewith a minor correction: 
At 6 N, R\c Maje should be written with an accent, 
as I have given it. 
I may add that I have just returned from travel in 
that section and find another map discrepancy that you 
might keep in mind, although probably you may not wish 
to make any change until the question has been acted 
upon by some of the name-fixing authorities. 
At 6 M-N, you will note two rivers emptying into a 
bay near Chiman. The names on these two are confused. 
The one at the west marked Rio San Francisco should be 
Rio Chiman. The one shown as Rio C himan is properly 
the Rio Francisco Ruiz. This hea<ds on the Cerro 
Francisco Ruiz in the Serrama de Maje. I have given 
this information to Colonel Petit of the Inter-American 
Geodetic Survey that possibly it might some time be 
corrected on base maps of the area. 
Sincerely yours. 
hs 
A. Wetmore, 
Secretary.
