Mr. A. Wetmore, Secretary

Dear Mr. Wetmore: 
Thank you very much for your letter of May 8 and 
for the two first-hand corrections on our Esso Standard 
Oil road map of Panama. 
We certainly appreciate your taking the trouble to 
call these changes to our attention, for we are right 
now revising this base map for another edition. 
It is gratifying also, to know that you have found 
the Esso map useful enough to wear out your copy. We 
are enclosing an additional copy as replacement, and 
will send you a copy of the new edition as soon as it 
comes off the press. 
I am also enclosing a reference copy of our new Esso 
ma.p of South America on the chance that you have not 
yet seen it.
