In its habits the Chub so far agrees with several others of 
this family, that it is found only in rivers which possess a 
good depth and supply of water; and also that it manifests 
much sensibility to changes of temperature in the different 
seasons. But, on the other hand, it prefers those streams in 
which the water flows with some considerable rapidity along 
a clean bottom of sand or gravel; and so needful to its 
well-being is a supply of what is aflbrded by a current, that 
it is not easy to keep it alive in a tank, or within the narrow 
limits of a pond. It is necessary, however, that its native stream 
should possess some safe and shaded pits or deeper recesses, 
to which it may retreat from danger, of the slightest appearance 
of which it is timidly sensible; and also where it may hide 
when the sun shines hot, and during the colder season of the 
year. From some causes connected with this repugnancy to still 
or stagnant water, or to the want of congenial retreat, this 
fish does not exist in the rivers of the north of Scotland, or in
