40 Rocking does not always bring sleep. 
in the shed, and was continually crawling round, using the 
ventilator-holes and back door to follow the birds when they 
left the eyrie. He had in this way managed to shift the stones 
that supported the trestles, so that the shed became unsteady, 
though safe enough, and so the first time G. A. Booth shifted over 
to look seawards through the ventilator-holes, he not only saw 
nothing but sea beneath him, but the shed flopped over with him 
and gave him a rare start, convincing him that the only safe thing 
to do was to keep to the landward side of the shed. To make 
things worse, it blew half a gale during the night, and the rocking 
of the shed on the unsteady trestles prevented him from getting 
a wink of sleep. I think he showed great coolness in not getting 
outside to attend to his safety, although afterwards, when he saw 
all the arrangements, he laughed heartily at his fears. 
F. Heatherley’s watch, from 1 p.m. May 27th, to 3.30 p.m., 
May 28th.—The day being very hot, the youngsters shifted about 
all the afternoon with the turning sun, to find shade for their heads 
as they slept. At 4 p.m. the Tiercel pitched on A with a puffin. 
He screamed the alarm as he flew down, and not a youngster 
stirred. He stood there silent for five minutes to assure himself 
that all was well, and then dropped into the eyrie. The young 
immediately clamoured round him; they seemed very hungry. 
At 6.10 p.m. the Tiercel pitched silently on B with a gory lump of 
flesh that might have been half a pound of butcher’s meat under 
his talons, there being nothing else left of the bird. Then he 
picked it up and, jerking his head forward, peered in all directions 
with it swinging from his beak, before he dropped into the eyrie. 
The young are for the first time showing some of the quilled 
primaries, so they are in the same stage as the young were in IgIo, 
when we first found them. At 8.47 p.m. the Tiercel came silently 
with what looked like a plucked puffin. The feed lasted twelve 
minutes ; the young were ravenous, and at the finish were quite 
gory about their beaks. To-day has been very hot, and the heated 
roof, close to my head, has been very trying. At 9.15 the Tiercel 
came down on to A and took up his position halfway along it for the 
night. Twice when I happened to wake in the night and looked 
out he was standing there in the moonlight.
