and respected as a man of stimulating theories, theories that the Indians 
thronged to hear. 
This visit more than fulfilled the expectations that arose when we first con- 
lceeived of the project more than a year ago. We would welcome other such 
ships. We are submitting a full report to the U.S. Information Agency, Wash- 
ington, D.C., a copy of which I hope you will see. 
Sincerely yours,

DeEAR Dr. STEWART: The Council of the Ceylon Association for the Advance- 
ment of Science, and the Ceylon Committee for the Indian Ocean Hxpedition 
wish me to convey to you, Captain Brown, and the other members of the Pioneer 
their sincere thanks for the most interesting and instructive seminar. The 
Ceylonese scientists who were present at the Seminar learned a great deal from 
the lectures delivered at the seminar and were very enthusiastic about the work 
of the Pioneer. 
For me personally it was an honor and a privilege to have been associated 
with you and the staff of the Pioneer. 
May I be permitted to add that I deeply appreciate the kind references you 
made and that I shall treasure the lovely medal you were so kind to honor me 
with. 
Good luck to the Pioneer and bon voyage. 
With kindest regards. 
Sincerely yours, 
R. O. B. WISESEKERA.

Dear ADMIRAL Karo: It has been a great pleasure for me to have accompanied 
one leg of the Pioneer Indian Ocean Expedition and to have been with the group 
during the week in Calcutta. I think the Survey will be proud of the results of 
this expedition. It is not only accomplishing important scientific results but is 
also adding much to the prestige of the United States by the fine cooperation 
with USIS in getting across to the nations visited the purposes of the work. The 
fine series of lectures, seminars, and press conferences, combined with the 
friendly social gatherings in Calcutta certainly left a splendid impression on the 
Indian scientists and engineers. Thanks to Dr. Stewart’s carefully made 
arrangements and advance notices, geologists and geophysicists from all over 
India came to attend the meetings and to see the ship and equipment. It was 
just the sort of international exchange that is so badly needed to increase our 
prestige. What an ideal combination of having Captain Brown in command 
and Dr. Stewart as chief scientist. They both make such a good team and their 
spirit is so contagious. 
I was glad to get to sea because I am afraid that Dr. Stewart would wear him- 
self out with his constant activities during the visit to Calcutta. He never 
seemed to have any time to himself at all. Since we sailed he has had a slightly 
more restful time but stands long night watches following closely all of the 
activities and contributing in so many ways to the success of the work in the 
Bay of Bengal. It is a pleasure to see how eagerly every one in the crew 
cooperates in the work when they have the kind of leadership that exists here. 
Much has been accomplished in unraveling the mysteries of the interesting 
valleys and canyons in the Bay of Bengal. It was unfortunate that there was 
no better means of obtaining positions during the work out beyond shore control. 
I hope some day when controls are made available that one of the Survey ships 
can return and really make an accurate map of this interesting bay. Also it 
will be better when Survey ships are better equipped for coring, dredging, etc. 
Much valuable time is lost by the difficulty of holding the ship in,position during 
coring or in proceeding slowly ahead during dredging. I realize that these diffi- 
culties were unavoidable for the present cruise and that this is just a start in
