is thus frequently induced to fly in circles round the 
canoe, and often attracted within gun-shot. In water, 
they are watchful, and dive so instantaneously, that it 
is difficult to shoot them. They take wing, however, 
with difficulty, although they fly well ; and this circum- 
stance enables the hunter to destroy great numbers of 
them in the spring. They arrive in that season when 
the ice of the lakes continues entire, except, perhaps, 
a small basin of open water where a rivulet happens to 
flow in, or where the discharge of the lake takes place. 
When the birds are observed to alight in these places, 
the hunter runs to the margin of the ice, they instantly 
dive, but are obliged after a time to come to the 
surface to breathe, when he has an opportunity of 
shooting them. In this way upwards of twenty were 
killed at Fort Enterprise in the spring of 1821, in a 
piece of water only a few yards square. In the 
summer and autumn, they are often caught in nets set 
for fish. The flesh of the northern diver is tough, and 
is eaten only through necessity.” — Richardson .
