Dear Walterj- 
Tlmnk you for your good latter of Daowiber 17, I have 
still another crab which I want to send you for axoaination, 
fhis last one we picked up in Petersburg, it was rery soft and 
much was covered with barnacles. This one did not get frosen and 
so eoraparlson with -Wi© others it fsay be a little difficult, I 
had to preserve Min in fonaalin. the logs of these crabs aevor 
do get definitely hard, there is al^mys considerable give to thoai, 
I was wondering if we should have a pressure gauge to laaesur© the 
ooinpressibility of the raerus the third right leg. This particular 
crab is not at hand yst, I had hoped tMt the siiipraent would b© 
forwarded the day after I started home but I have just received 
word tJmt it just left the wost coast. 
Mien I see the barimoles on some of these crabs I aB 
quite coiwinced that the larger ones at least molt only once in 
two years# I cannot conc©i%’^0 that baniacles grow so large in just 
one season* I sent Hr* Cornwall some bamaclas tliat had been 
taken from a two year old trap that had been picked off the bottom 
with our trawl but as you know he has had to relinquish his study 
for ?mnt of funds. He is no^if -stationed in -British Columbia. I 
wish tliat it -might haire been possible for the Station to ha^e carried 
him along for another few year-s. 
I would haTc given anything to have seen you again but 
it wasnH possible "id.th the xmmhnr ot things that the -Bureau loaded 
on my b-ack in Seattle* W© measured between i ^ ^ 
crabs ^ the ma-asurements that we discus-sed inoludi-ng length height 
and thickness of the larger chela, part way through we took, in 
addition, tiie distance across the articulation of the propodus with 
the dactyl. We did not get any crab in tJie actual molting stage 
or get any of our crabs to molt* Harvey told me before we started 
tliat W0 ware coirdng back just when we should have been going north* 
Marukawa seems to have it right for tlm time of year at wiiich it
