sides slate and one plate-glass ; and it should be so 

 arranged that access can be readily had to the water, 

 BO that dead or dying animals or plants may be re- 

 moved as soon as they are observed. The special 

 cultivation of animals in conjunction with plants 

 ■would, however, require a volume, and is foreign to 

 the purpose of this work. 



The following British Aquatics could be grown 

 either in-doors or out of doors, provided that they 

 are not exposed to frost. The Foreign Aquatics 

 require a warmer temperature,

Marsh Plants. — There are many interesting 

 plants to be found in boggy and marshy places which 

 may he cultivated without much trouble. They 

 should he potted, not in soU, but in moss ; the b6st 

 kind of moss for the purpose is Sphagnum, of which 

 several species are to be found in bogs and wet 

 localities. Growers of Orchids are well acquainted 

 with it under the abbreviated name of Sphag. ; but 

 they use it in a damp condition, while for growing 

 marsh plants we must keep it saturated with water, 

 by standing the pots in saucers 

 and keeping them well sup- 

 plied. 



As these plants are found 

 in places where dust is an un- 

 known material, it may be 

 imagined that this is likely to 

 prejudice their healthy growth 

 to a serious extent if allowed 

 to accumulate. It wiU, there- 

 fore, be desirable to wash this 

 off every day with a watering- 

 pot having a fine rose ; but aa 

 prevention is better than cure, 

 it will be the best plan to keep 

 all such plants, when grown in 

 a room, under a cover or shade, 

 thus protecting them as much 

 from the dry air as from the 

 dust.
