The second part of the oceanographic survey will be a three week
cruise, cne month after Hardtack, for the purpose of determining the

The plans for sampling the tuna in the central and waatern Pacific
are now being formulated. A plan that would accomplish this purpose
would be to sauple the tuna at the port where the Japanese fishing
veseels land their catch. If the samples can be identified as to place
and date of capture this would be the most desirable method of sampling.
Obtaining the samples should be arranged with Japanese fisheries people
or other scientists and the samples shecad with them if they so desired.
