tanks for aquaria. I can recommend either of these 
houses with the greatest confidence. 
Construction of Tanks.—As this work may reach 
many remote districts, where an aquarian would find it 
difficult to get a tank properly made, a few hints on the 
proper mode of construction may be acceptable. 
It must be borne in mind, then, that when a tank is 
filled, its weight is enormous, and hence it is difficult, 
sometimes impossible, to move it without first removing 
the whole or greater portion of its contents. Strength in 
the joints to resist pressure from within, and strength in 
the table or other support on which the tank is placed, is 
of the first importance, The bottom of such a tank as we
