100 COMMON YELLOW WATER-LILY. 



and especially in those deep pools formed near the 

 margins of extensive lakes, or in immediate connec- 

 tion with them. So situated, the Nuphar is often more 

 conveniently within the easy reach of the botanical 

 collector than the Nymphsea ever ventures. The pre- 

 ference which this plant shows for pools and shallows 

 seems to recommend it as peculiarly suitable for cul- 

 tivation where the accommodation of a large pond, 

 so necessary for the Nymphsea, cannot be had. It 

 must not, however, be supposed, when we mention 

 the plant as growing in pools, that, under cultiva- 

 tion, it will thrive in any sort of a muddy puddle. 

 All the family of Water-Lilies love pure waters, 

 clear as crystal, and attention to this fact is the 

 main element in their culture.
