We also want to Increase the no*bar of Berlese samples. Take 
15-20 samples per week out of the eooty colony area; 1 believe 
we'll tee a population change, tickvlte, «e the tootles return end 
we Bust document this. Continue to take material frost albatross 
and booby nests, end as other things start to nest, l.e. frigates 
and rod-foots, run some of their nests also. Big out Bonin end 
old vedgatail burrows end run material from those also. Bun litter 
material from all ever the Island, keeping careful track of what 
areas are sampled. Wo must obtain a largo statistical sample on 
this Berlose materiel this spring, and negative data Is Just as 
Important as positive. "Sto .ter Berlose samples in the ectoparasite 
catalog. 
A couple more things on blood work. Be sure to get blood 
samples from sick Leysans and mako sure you havo 3 or 4 frozen 
ones to bring back. Cam should bring these end the seal skin beck 
frozen with him. If you're not coming back to D.C. take them to 
Bono and have that sent to mo air express and telegram me as to 
what airline, flight number, airport and specific time they'll be 
arriving here so we can arrive to meet them. Are you using the 
station's refrigerator for blood samples; I'm assuming you are. 
Talk to Dave and sake aura this Is creating no problems for the 
station, for if It Is wo should get a small refrigerator of our own. 
Wo should continue the seal pup work this spring, for even 
though the project Is not Interested It would be a shame to pass 
up the opportunity to add to the limited knowledge an this species. 
Check the beaches carefully for pups end t ag and weigh them as 
clooo to birth as possiblo, and at weekly intervals thereafter. 
The measurements I've taken, done each time they're weighed, are as 
follows. Total length - from the tip of the snout to the tip of 
the tall with the pup stretched fall length on the sand, someone 
will have to ly beside It end hold It stretched out - they don't 
bite; Tall - length of that portion which protrudes from the skin; 
Hind flipper — two measurements, one of each lobe, taken from the 
fold between the tall and one flipper to the end of the upper and 
lover lobe respectively, of one flipper; Tore flipper - taken from 
the "armpit" with the point of the rule pressed against the rib 
cage, to the end of the flipper; Girth - wrap the tape around the 
chest just behind the fore flippers, so that It runs through the 
* armpits". 
Here's e problem for Bob's microclimate work, if you haven't 
already discovered It. Blnlon discovered on Send that there 1 b 
significant elactridel leakage In the soil from the loran and trans¬ 
mitting antennas; this can be detected several miles away; which 
adversely affects the telethermoaeter. Check your soil temperatures 
with e hand thermometer for this. Check air temperatures likewise 
although there shouldn't be any significant effect here. I would 
do all the work at tha south end of tho island. If you brought your
