LEAST PETEEL. 
into every hole, they hid themselves between the feet of the table and the 
wall ; I could not prevail upon them to eat anything, though I tried to tempt 
them with fish and oil ; their manner of walking is very light and pleasing, 
and differing from that of every other bird which I have seen ; they carry 
their body so far forward and so nearly horizontal, as to give them the 
appearance of being out of equilibrium. In the evening, to.ward sun-set, 
they left their hiding-places, and for hours afterwards, never ceased in their 
endeavours to regain their liberty ; flying round and round the room, or 
fluttering against the windows ; when flying, their length of wing, and white 
above the tail, gives them a good deal the appearance of our House-Martin. 
I went to b v ed and watched them in their noiseless flight, long ere I fell 
asleep, but in the morning they had disappeared ; one had fortunately made 
its escape through a broken pane in the window which a towel should have 
occupied, the other had fallen into a basin, full of the yolks of eggs which I 
had been blowing, and was drowned. I regretted much the ffcte of a being 
so interesting, by its very remarkable, wandering, solitary, and harmless life. 
Before leaving Shetland I again visited the island of Oxna, and though so 
late as the 30th of June, they were only just beginning to lay their eggs. 
In Foula they breed in the holes in the cliff, at a great height above the sea ; 
but here under stones which form the beach, at a depth of three or four feet, 
or more, according to that of the stones ; as they go down to the earth, 
beneath them, on which to lay their eggs. In walking over the surface, I 
could hear them, very distinctly, singing in a sort of warbling chatter, a 
good deal like Swallows when fluttering above our chimneys, but harsher ; 
and in this way, by listening attentively, was guided to their retreat, and 
after throwing out stones as large as I could lift on all sides of me, seldom 
failed in capturing two or three seated on their nests, either under the lowest 
stone or between two of them. The nests, though of much the same 
materials as the ground on which they were placed, seem to have been made 
with care ; they were of small bits of stalks of plants, and pieces of hard 
dry earth. Like the rest of the genus, the Stormy Petrel lays invariably 
one egg only. During the day-time they remain within their holes ; and 
though the fishermen are constantly passing over their heads, (the beach 
under which they breed being appropriated for the drying of fish,) they are 
then seldom heard, but toward night become extremely querulous ; and when 
most other birds are gone to rest, issue forth in great numbers, spreading 
themselves far over the surface of the sea. The fishermen then meet them 
very numerously ; and though they have not previously seen one, are sure to 
be surrounded by them upon throwing pieces of fish overboard." 
The egg measures one inch and an eighth in length, six and a half eighths 
in breadth, is nearly equally rounded at both ends, rather thick-shelled, and
