Lehner, P. 1964 Nov. 26 Thanksgiving Bihion and I were up for the first watch; at 7:20 A.M. a head bolt on the starboard engine broke and the rpm's had to be dropped from 638 to 400; our speed has now been reduced to 8.8 knots; also we cannot shoot any but the most rare birds, as the captain has fear of changing speeds with the engine - they have used up all their spare head bolts, so we are forced to limp the rest of the way; the wind blew in from the East causing a fairly choppy sea; large swells continue to roll in from the northwest; the skies were overcast all morning and the air was a bit chilly; nothing much happened until we again took the watch at 3:00; the wind had now changed and was blowing from the northwest and combining with the swells from the same direction to send the ship into 20° rolls occasionally; the number of birds seemed to pick up throughout the afternoon; dinner was a combination Thanksgiving dinner and Captain's dinner; we had one rain squall at 4:00, but the skies had threatened all day; the watch was secured at 6:07 P.M.; frequently throughout the evening Sooty Terns could be heard flying around the ship - Mr. Ashton said that one landed on the bridge but he could not grab him before he flew; at 11:15 a white rumped storm petrel flew onto the flying bridge and was caught; at 1:30 A.M. on the 27th another flew aboard and was also caught; they were both held alive in Lab #2.
