Dear Rogers 
This is by no means the end of what we will have to discuss 
regarding the report you have outlined on the or*b investigation. It 
is a grand outline that you have prepared and, offhand, I can really 
add nothing to it except to suggest that embryology should be in- 
cluded, and your term "reproduction" more or less would take care of 
that# 
The biology of the king crab* which takes in Hos# 3 to 6 
of your outline* should be Wallace^ min ^ob* with Pat and Art 
assisting him with whatever work on which he needs help# Incidentally, 
there wifi be a lot of plotting to do in connection with the distri- 
bution* growth* and migrations# By the way* migrations should be 
alongside of distribution* Art could specialise* as you suggest* on 
the distributions and Pat* as I have mentioned before* might undertake 
the embryology* I have a number of egg samples which he pickled for 
a study of that sort* It will not need to be profound* but we do want 
to know something about the ripeness or degree of development that 
the eggs show in the course of a year# If Pat has a lot of stomach 
contents* also in line with your suggestions* he can begin sorting 
the contents of each stomach into vials so that we may get an idea 
of the principal food that the crabs ingest in the different localities# 
I have material her# of soma ten or twenty stomachs which Pat can 
sort, and I can assist with the identification of the contents after 
the sorting has been done# I can ship these out, along with a supply 
of vials, whenever he is ready for than# 
I am really glad that you have called Wallace back to begin 
on the report# It is a keen bit of foresight, and I am packing up the 
sheets; of measurements that Pat and I mad© on the first csruise# Wallace 
will need to have them# Me Mi lien will be able to give him some very 
excellent counsel in looking up his growth data# 
What you have assigned to Carl and Roy they can do best, 
and I suppose Joe has given you about all you need on the canning 
angle* I shall help out wherever I can, perhaps with the food habits
