Tnesrlav fin^llv arrived, brining with 
it a c Q ln sea, a light easterly breeze and 
overcast sky* George and Ken had the first 
watch and collected what has tentatively bean 
identified as a Kermadec Petrel(it was first 
then *ht to he r. Herald’s Petrel): Binion and 
I took the watch at G :00 and minutes later 
collected a White-necked Petrel — the crew is

valuble time by having In maneuver to nick un- 
birds* we passed a lonm line of fish hells 
with cane noles and flays - they were strung- 
out east and west and urdcubtahly marked a

ones that had "learned to flee at an unusual

I noticed that the larme ones vern seldom
