A ZOOLOGICAL RECONNOISSANCE IN GRAND 
MANAN 
BY J. WALTER FEWKES. 
3 the side towards Eastport, Grand Manan presents a series 
of lofty cliffs rising abruptly out of the sea, so precipitously 
that it would be almost impossible to climb from the shore to 
their summits. Only in a few places is this rampart broken 
through, leaving sheltered coves where boats can find anchorage. 
Ordinarily the lofty cliffs rise abruptly from the sea, and the few 
stretches of beach crowded in between the foot of the cliff and 
the water are exceptional, and limited in extent. Deep into this 
lofty buttress of rock there extends at one point on this side of 
the island a deep fiord, known as Dark Harbor, so-called because 
in former times its heights were covered with sombre trees. The
