 collected, and wherein the plants themselves, either in tubs 

 or pots, are plunged at greater or less depths, according to 

 circumstances.

 conveniences : some aquatic plants having very considerable 

 roots, do not well admit of being confined in small tubs or 

 pots ; at least these tubs and pots, when filled with growing 

 plants, and the earth that surrounds them, become too heavy 

 to be properly managed. Besides, if the basins are so con- 

 structed as to receive the water from artificial fountains, or 

 jets, the fall of the tumbling water necessarily disturbs the 

 vegetation of the plants which it reaches, and spring water 

 is at all times too hard for the nourishment of plants ; for
