MAMMALIA—WHALE. 397 
straight as an arrow, about the thickness of the small of a man’s leg, wreathed 
1M \.* Manner we sometimes see twisted bars of iron. It tapers to a sharp 
port and is whiter, heavier, and harder than ivory. It is generally seen 
to spring from the left side of the head, directly forward, in a straight line 
with the body ; and its root enters into the socket above a foot and a half. 
Notwithitanding its appointments for combat, this long and pointed tusk, 
amazing strength, and matchless celerity, the narwhal is one of the most 
harmless ind peaceful inhabitants of the ocean. It is seen constantly and 
inoffensivy2ly sporting among the other great monsters of the deep, no way 
attempting, to injure them, but pleased in their company. The Greenland- 
ers call th: narwhal the forerunner of the whale; for wherever it is seen, 
the whale is shortly after sure to follow. This may arise as well from the 
natural passion for society in these animals, as from both living upon the 
sanie food. The narwhal is much swifter than the whale, and would never 
be .aken ly the fishermen, but for those very tusks, which at first appear 
to be its principal defence. These animals are always seen in herds of 
several ata time; and whenever they are attacked, they crowd together 
in such a manner, that they are mutually émbarrassed by their tusks. By 
these, they are often locked together, and are prevented from sinking to the 
bottom. It seldom happens therefore, but the fishermen make sure of one 
or two of ths hindmost, which very well reward their trouble.
