Excerpt from letter from Prof. H. Pittier, dated Culebra, 
C. Z. , May 10, 1911. 
"Mr. D. McDonald, geologist to the I. C. C., has just informed 
me that Dr. Dali wishes me to accompany him to Port Limon, Costa 
Rica, and is to arrange the matter in Washington. As my plans for 
the future may he influenced by your decision on this point, I beg 
you to kindly communicate with Dr. Dali and to let me know the 
result. If you deem it desirable that I should go, I think that 
it will take me at the utmost five days to show Mr. McDonald all 
the outcrops where my fossils were collected and that I would come 
back to Bocas del Toro for one or two weeks, a trip that is included 
in my program."
