Otters are mainly aquatic in their habits, and their food is fish, 
which they capture by swimming. In the water the Otter moves 
with ease, its action even graceful, and it dives instantaneously 
either to escape danger or to pursue its finny prey. The nest or sleep- 
ing place of this animal is formed of grass, and is usually placed 
among the roots of a tree, or in a hole in the bank of a stream, or in 
the hollow of a tree near water. As a digger the Otter is not famous, 
and its retreats are usually those formed by nature, or by some bur- 
rowing animal. Otters are playful creatures, and their chief amuse- 
ment is sliding. The highest place in the bank, or if in winter the 
topmost ridge of snow is selected, and lying on its stomach with the 
front legs laid backward, giving itself a push with the hind feet, it 
glides head-first down the declivity, and this is repeated many times,
