ATF - 6l- 
rain let up Binion , Allen and I started gridding the island. We set 
£ 
up H~S compass lines from opr base points, -which are lettered, and then 
put in flags every 100 feet* along them also. The base line was arbitrarily 
designated 10, and all points north of it will be over 10 and those south 
of it under 10. The square 100 feet north and east of a stake will bear 
the number of that stake. A terminal, stake was placed at the north and 
south end of each line, at the edge of the island and above the beach 
(above high water), and these stakes were marked with the letter desig¬ 
nation of the line and the total feet north or south of the base line to 
that point. 
We noted more tropiebirds about the islands today, and they are 
beginning to land and sit on the ground in pairs for short periods. The 
clouds of terns which have hung over the island since we arrived are 
beginning to spend more time on the ground, even landing in the daytime 
now, which they did not do the first few days. Both the soot ft and Bonin 
petrols are numerous on the ground at night, the former being more common. 
Both species are digging barrows, two birds may be seen at one burrow, and 
they are calling from within the burrows. 
After dinner the evening the weather began to clear, and the whole 
group went over the western portion to work on black-foots as we did hast 
night. There were not as tunny birds tonight, and after finishing at the 
west portion 2 teams worked on black-foots on the eastern portion and the 
third team band&d petrels and. tenrs. 
Banding totals for the day were 475 black-footed, 6 brown, 
and 2 masked boobies, 37 Bonin and 23 sooty petrels, and 9 terns. 
Seal no 93 lay on the shore in front of the camp all day today. She 
was only about 75 feet from my tent, and 5eeme to have a favorit'^e spot
