THE FULMAR: ITS PAST AND PRESENT DISTRI- 
BUTION IN THE NORTH ATLANTIC AND IN 
THE NORTHERN PARTS OF EUROPE AND 
NORTH AMERICA, AND SOME ACCOUNT OF 
ITS GREAT INCREASE IN GREAT BRITAIN. 
By J. A. Harvire-Brown.

(Puates I. & II.) 
FoREWORD. 
Darwin tells us that the Fulmar Petrel is ‘“‘ the most abun- 
dant of all Arctic birds.” We may rest satisfied, as we fully may, 
on such an authoritative statement—at least, until such times 
as better methods of taking a census of bird-life be divulged— 
say, by cinematograph photography—and so be content— 
‘‘To dream of the womb of the Future, 
Charged with the fulness of Time.” 
GENERAL DISPERSAL. 
There are three causes which appear to have influenced and 
regulated the dispersal of the Fulmar Petrel and its successive 
occupation of new nesting sites in recent years, one of which 
seems to be the most important, and the other two less so and 
more local in action. 
The first of these, the earliest and almost assuredly the 
really dominating force, has been the rapid increase of their 
numbers at their more northerly breeding stations, and the 
natural expansion caused by the congestion in an outward and 
a southerly direction.
