however, and just the thing for labora- 
tories, schools, kindergartens, ete. The 
exterior of such a tank can easily be 
ornamented with wooden moulding to 
suit one’s fancy. One of our illustra- 
tions shows one, of a large pattern in 
this case, that is decorated with fluted 
pillars and otherwise trimmed to form 
a design somewhat Greek in appear- 
ance. The wood is stained a dull black, 
to represent antique and the 
smaller borders are kept in a shiny, 
iron, 
creamy white, to represent old ivory. 
The effect of the whole is very pleasing. 
The American Angler 
window with hooks. Over the tops of 
both is a wire-cloth screen, to prevent 
books or lunch remnants from coming 
in contact with the water. 
The 21 inch size is a good shape for 
a breeding tank. When one wishes to 
raise some young Paradise or gold fish, 
or for breeding sticklebacks, its length 
permits dividing it in two or more 
apartments by simply placing one or 
more panes of glass between the sides. 
The window sill aquarium, repre- 
sented in another illustration, it will be 
observed, -is rather long compared with 

Twin Aquaria. 
The stand on which it rests forms an 
antique oaken cabinet. 
Two of the above mentioned smaller 
sized tanks might be used on one win- 
dow-sill; they would then form a twin 
aquaria. (See illustration.) The ad- 
vantages of such a screened twin aqua- 
ria are very important, especially in 
kindergartens. Each tank can be stocked 
with different objects; each one can be 
changed and rearranged without molest- 
ing the other; both are protected by 
an ornamented front, which hangs on 
hinges below, and is fastened to the 
its width and height; it is designed 
for an ordinary window sill. The di- 
mensions, 30 inches in length, 12 inches 
in height, and ro inches in width, ex- 
perience has taught us to be the correct 
ones for the welfare of the collection 
and convenience of study, as well as 
for ornament. 
In the tank represented, each end is 
formed of one solid plate of cast iron; 
against these the upper and lower bars 
that form the front and rear of the tank 
are fastened. These ends are lined 
with ordinary glass. The bottom con-
