heat. In cases of sudden low temperature some means of 

 protecting the plants should be at hand. 



Soil. The soil best suited to the growth of most of the 

 aquatics, especially the water-lilies, is one made of equal 

 parts of good garden soil and well-decomposed stable ma- 

 nure. If the plants are grown from seed, they need to be 

 transplanted two or three times until large enough to put 

 into the open air, when they should be planted in a box or 

 tub or be sunken in the mud, in a pond or tank, pressing the 

 soil firmly about the roots, and then covering the surface 

 of the soil with coarse sand or gravel. It matters little what 

 the depth of water over the plants is after well established; 

 it may be 3 inches or 3 or more feet; but for the water-lilies, 

 it should never get so low as to have the leaves rest on the 

 soil for any considerable length of time. After good growth 

 has begun, if the soil is in the proper condition, but little 

 care need be given except to see that the water does not 

 all evaporate, or that muskrats do not get at and destroy 

 the roots, of which they are very fond. . Every means 

 possible, by poisoning, trapping, shooting, etc., should be 

 taken to get rid of the above pests, as a single pair of these 

 animals will destroy a large number of plants in a short 

 time. Among the plants that grow directly in the water 

 are the following : 



Lotus, Egyptian. Water-lilies, Royal Purple. 



Lotus, White Japanese. Water-lilies, Superb. 



Lotus, Striped Japanese. Water-lilies, Devonian. 



Lotus, Native. Water-lilies, East Indian.

Water-lilies, Large-flowered. Water-hyacinth. 



Water-lilies, Yellow-flowered. Water-poppy. 



Water-lilies, European. Salvinia. 



Water-lilies, Day-blooming. Papyrus, Egyptian. 



Water-lilies, Purple African. Flag, Variegated.
