68 A MANUAL 



Earthenware vessels, brown pans, pie-clislies, foot- 

 pans, are useful for the commoner sorts of anemones. 

 A stone-trough, 2 feet by 14 inches, makes a capital 

 preserve or nursery, when placed under the shelter 

 of an alcove or summer-house, and the more porous 

 the stone is the more equable (during the heat of 

 summer) will be the temperature of the water it con- 

 tains. It should be set on a slight incline, and have 

 a hole bored at one extremity with a cork fitted to it, 

 in order to drain off the water for cleansing purposes. 



1 will briefly describe a more elaborate receptacle of 

 this latter kind, and then leave my reader to exercise 

 his ingenuity in devising " aquaria" for himself. 



Take a large slab of oolite, say 4 feet by 2, and 



2 inches thick; bore two holes in it, one J-incli 

 diameter in the centre, the other an inch in diameter 

 close to one end, and fitted with a cork, or a pipe and 

 tap. Let this slab form the bottom of the tank, 

 groove it, therefore, and fix upon it, with Portland 

 cement, four sides of stone of about 8 inches in 

 dei)th. Suppose our trough, thus constructed, to be 

 fixed out of doors, but under the cover of a verandah 

 or summer-house, some few feet above the ground, 

 on an incline of one in twenty-four, and to be sur- 

 rounded with ornamental rock-work, and x)rovided 

 with a drain to carry off the refuse water Avhich 

 escapes from the lower of the two orifices ; it tlien 

 only remains to fix another trough on the top of tha 

 summer-house, and to connect the two tanks by a
