 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 afforded 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
