_ out to his companions, “some Falcons’ eggs,” and carefully unpack- 
ing his bags, there in the small pocket, he exposes to our view four 
splendid eggs of the Peregrine Falcon, which I afterwards purchased. 
He describes the nest as resting in a ledge- of the cliff, made of 
sticks and seaweed ; lined with grass and sea birds’ feathers. The 
clutch of four eggs were very handsome, of a light pinky brown ground 
color; mottled and blotched with various shades of dark brown. In 
the large pocket he has some fine clutches of Kittiwake, Herring and 
Lesser Black-backed Gulls, with a few Guillemots, Razorbills and 
Puffins. 
Moving on a little farther, the ropes and bars are again fixed and 
the man who made the first descent again is lowered, and after a 
short time appears as before with his bag well filled. This time he 
unpacks his bag it contains eggs of the Cormorant, Guillemot and 
others as before, and in the small pocket he has eggs of the Jackdaw 
and Kestril Hawk. The latter makes a nest of sticks and grass on 
a ledge of the cliff, and lays four or five eggs of light red ground col- 
or; mottled and blotched with rich, dark brown. 
The Jackdaw makes a similar nest ; but its eggs are of a pale bluish- 
white, well spotted with ashy, light and dark brown. The Raven 
formerly nested on these cliffs ; but is now seldom seen in this local- 
ity. 
The climbers are still at work, and by lying on our stomachs and 
carefully crawling to the edge of the cliff, we can see a number of 
nests of the Kittiwake Gull, built on the ledges below. ost of them 
contain two eggs ; but some have three, ‘whilst one nest contained two 
young birds, a few days old. 
The Guillemots’ and Razorbills’ eggs are laid on the ledges of bare 
rock (some of which are only a few inches wide), and it seems a. 
marvel that the eggs are not blown off; but the reason is this, that 
the eggs are placed with the thick end to the cliff, and instead of 
rolling off they revolve around, the narrow end of the egg acting as a 
point. 
The largest number of eggs taken in one haul is about one hun- 
dred, chiefly Guillemots and Razorbills. There have been a few 
serious accidents to the climbers during the past few years ; two hav- 
ing arms and legs broken, and one has been killed outright. 
When the climbers consider they.have done a good mornings work, 
they sort out all the rarest and best eggs, which are sold to collectors
