WILD SWAN. Crass IL. 
The cry of this kind is very loud, and 
may be heard at a great distance, from which 
it is sometimes called the Hooper. When 
they fly high, and numbers of different ages 
and sexes are joined together, their notes are 
‘far from disagreeable; and as some alledge, 
are even musical. On the contrary, the tame 
species is almost dumb, for it never emits the 
least sound beyond a hiss, which it does when 
provoked. Other distinctions between this and 
the next species, are these: the Hooper carries 
its neck erect, like a goose; the other bends it 
in swimming; and is far inferior to our tame 
Swan in size. ‘This species has twelve ribs on 
a side; the other only eleven: this species has 
a windpipe with a double and great flexure, to 
which it owes the modulation of its voice; the 
windpipe of the other is strait. 
These birds swarm during summer on the 
larger lakes and marshes of the Tartarian and 
Siberian deserts ; but resort in vast numbers to 
winter about the Caspian and Euine seas. 
Those of the eastern parts of Stberia retire 
beyond Kamtschatka, either to. the coast of 
America, or the isle north of Japan. The Rus- 
sians frequently tame this species; very rarely 
that which we call the Tame Swan.
