Mr. Ratibor Hartmann, 
Gorgas Memorial Laboratory* 
Apartado #1252* 
Panama, R. de P. 
Dear Ratibor: 
I am very sorry to write that 1 have been delayed 
beyond my expectations in my plans for field work 
this year. It looks now as though it will be the 
first of March before I am able to come which has 
made complete change in my plans, particularly 
since this year I will have to remain in places where 
I can receive mail without too much delay. I will, 
therefore have to give up the plan I made of working 
in the remote areas of the Caribbean coast though I 
expect to get over there another year. 
Under the circumstances I do not believe that 
Mr. Perrygo and I will need to have Yaroslav as 
assistance since our trip will be considerably broken 
up. I wish, therefore that you will let him know 
that I will not need him this year. I will hope to 
have him with us again next season. I trust that 
this change will not inconvenience you or him too 
greatly. 
¥/e have had some cold weather here since I 
wrote you last, with snow and ice, but now it is 
moderating again. 
With my kindest regards, I am 
Sincerely yours, 
hs 
A. Wetmore, 
Secretary.
