 Sedums, Caladiums, Palms, etc., are planted. The effect 

 produced in this manner is really beautiful. See fig. 42. 

 The next best arrangement for growing aquatics is to 

 build of bricks and hydraulic cement a basin two feet 

 deep and six feet in diameter, either round or square. 

 This can be sunk in the lawn in a sunny position, or on

ENEMIES OF AQUATIC PLANTS. 



The conditions which we recommend for successfully 

 growing tropical aquatics (i. e.. still, warm water and 

 rich compost), favor the growth of a low form of vege-
