should fall very olose together or perhaps in the same section of the 
report. 
In so far as Sands has data for the areas where orabs were 
taken in promising quantities, I do believe he should contribute a 
section on the hydrographi o conditions. We ought to know the temper- 
ature and the salinity of the water in those regions for as many of 
the twelve months els data are available. 
As I mentioned before, I have in mind a brief resume of the 
systematics of the several speoies of Lithodid or king orabs that 
occur in the northern Pacific. That may be included in the report or 
left out, as seems best when it is about complete. 
1*11 promise to give you all the help that I can, because I 
want to see you make a good report of what information the expeditions 
have been able to get together, but it does not seem possible at this 
time that I can make the trip to the coast. If you really have to have 
me, I might make a shift to oorae, but I do believe I can give you all 
necessary help without making the trip. Our South American project 
has been moving along and a current year’s appropriation of considerable 
size has been approved. It does look as though this fall or early 
next spring I shall have to go south again, and meanwhile make no end 
of preparations looking toward spending the money. 
What Harukawa did on estimating the abundance of crabs on 
the larvae or eggs taken seems to me to be too highly speculative to 
be of use at all. Then, again, we must remember that his investiga- 
tions comprised seme eight years of work. I don’t believe I would 
even comment on his method of sampling abundance.

I do not know that we will be able to say anything about the 
age of the crabs. All of us believe, and that includes Weymouth, that 
Marukawa’S ages are far too great. 
We could have published our growth figures in decimal fractions 
of an inch, but since it won’t be so difficult to convert them It is 
very nice to have them appear in your report in millimeters, as they 
have appeared in all others of similar scope* Nevertheless, in your 
summarizing paragraphs you will have to give inches as well as milli- 
meters for the sake of the practical fishermen. The same is true of 
weights. It might look inconsistent to have measurements in milli- 
meters and weights in pounds, but pounds should receive a prominent 
place because the earners and fishermen talk only of English pounds. 
A little note from Pat tells me that they made some good 
hauls in Pavlof Bay. Yihen we were up there I suspected that some of 
the orabs allowed a two-year interval between moults. That, if true, 
would account 'for the dearth of tagged specimens. It makes me wish 
that you might get at least one boat for sli 11 another year of work 
in the hope that the tagged specimens might turn up. Even though
