This morning Allen, Binion and I continured gridding out the island# 
We went hack and checked some of our squares with the steel tape and 
found that some were 20—30 feet off. It w:S then decided to cisgontinue 
gridding this trip as our small hand compass is not sufficiently accurate 
to lay out these squares.

After lunch Morris and I went heck out to the sfeipgW water and 
some more provisions, Fred* Allen and Boh continued handing black- foots 
end Binion added to his insect list. 
At low tide this afternoon the group® waded along the exposed coral 
ledge and tid^l pool at the south side of the island end speared one 4 ft. 
white-tipped shark, a couple of small odd-shaped fish, and collected 3 spiny 
lobsters, which we ate for dinner. I wished for some melted butter, but 
they were quite good dispite this lack. There seem to he great numbers of 
these white-tipped sharks shout the island. They are never much over 4 or 
5 feet but it is not uncommon to see two dozen or more in one area# They 
move slowly among the coral heads and came within a few feet of the shore. 
I have seen seals in the water with them and they do not seem to bother 
the seals. Though today when I was out to the ship they pulled & 10 footer 
aboard with a 2 ft. hoov on a chain which we had to dispatch with the car¬ 
bine. I have observed the smaller sharks ch sing schools of small silvery 
white fish in the shallows on several occasions. 
The sooty terns are spending more time on the ground now and there 
are larger groups of gray hacks. Today was the first time I have seen 
^ rou P® of the latter on the ground in the day time, though they have been 
on the ground in the day time.
