PLANTS FOR THE AQUARIUM. 69 



Cerstilim tomentosum, Mouse-eared Chick weed, has a 

 small white woolly beautiful leaf, and for this genus a 

 large white flower. 



I have given a list of enough for a beginner, and shall 

 be happy to continue it if these structures at all increase. 



There are many other plants, not referred to in this ar- 

 ticle, which will be found in the body of this work, under 

 the heads of their respective genera, that are recom- 

 mended for rock-work. 



PLANTS SUITABLE FOE THE AQUARIUM OR 

 ORNAMENTAL POND. 



When a garden is so situated that it can be supplied 

 with living or running water, a collection of aquatic 

 plants in an aquarium, in connection with a fish pond, 

 will be an object of additional interest to the pleasure 

 ground. But on no account would I advise an append- 

 age of this sort to a garden, unless it be fed by a stream 

 of water or spring. A dug-out, even if water can be ob- 

 tained the year round, without an outlet or inlet, is a 

 great nuisance, and only fit for raising frogs, musquitoes, 

 and for the growth of green confervae upon its stagnant 

 surface. With a stream or never failing spring of water, 

 an aquarium can be made without much expense, if not 

 on too large a scale. It should be at least three feet 

 deep, and lined with a substantial stone wall ; it should 

 have a margin of grass, or be edged with rough or dressed 

 granite or free-stone, surrounded with a nice gravel walk. 

 The portion of aquarium designed for most plants, should 

 be three feet deep, in addition to a good depth of rich 

 soil, while the bottom of the other section should be laid
