As to the size of the tank, it very much depends on the place in which 
one has to put it. These three sizes I have found from experience very- 
useful : 
No. 1, Length, 18 in.; depth, 10£ in; width, 12 in. 
No. 2, Length, 24 in.; depth, 14 in.; width, 14£ in. 
No. 3, Length, 28 in. : depth, 13£ in.; width, 13 in. 
No. 3 is, perhaps, the best size of all, and it is by far the prettiest 
shape. Tanks can be purchased, generally, at the bird or plant stores of 
large cities; the prices range from six dollars upwards. Sometimes a 
stand for the tank is made in connection with it, or of a similar material. 
It is well to remember in selecting a stand, the enormous weight which 
it will have to bear when the tank is filled with stones and water.— To be
