Dear Roger* 
I don’t want to delay longer replying to your letter of 
July 9th. I judge that my letter of the 8th crossed yours in the mail* 
I am glad that Wallace is back with you to work on the re- 
port. Your outline, as I remarked, seems to cover rather fully what 
should be inoluded in your report. That report should be simple, di- 
rect, matter of fact, and factual* As I run it through my mind again, 
we want to knows 
1. Occurrence. 
2. Conditions under which the crabs live. 
3. Their food. 
4. Growth* rate of growth, relative growth, size, moult*# 
ing, and something about the embryology in so far as 
one can make out the degree of development attained 
by the eggs at different times of the year. 
6. Breeding grounds and nursery areas should be gone into 
rather fully, or as fully as we can. 
6. On aotual migrations we will have little or nothing, but 
we may be able to derive from the various measure- 
ments something about the populations of the various 
areas and a frequency curve for the distribution of 
the various sizes of crabs in the several areas or 
populations. 
7. Fishing methods* relative efficiency of the gear. 
8. Utilization and canning, 
9. Comeroial fishes encountered and the prospects for 
basing a fishery on them. 
10. Recommendations. 
In many ways this outline parallels yours. The order in which 
the various points should appear in the final report should be left 
until the several sections are complete, for, as I look baok over the 
list, occurrence, breeding grounds, migrations, and conditions under 
which the crabs live, which would include some oceanographic disousslon.
