Cages. On this head we need scarcely trouble our readers with many special directions. Canary cages may be made of every conceivable variety of shape; and, provided the comforts of the little inmates are properly cared for, as highly ornamented as taste or fancy may dictate. Either mahogany, or some hard, close-grained wood, should be used in their construction - the former is best; fir should never be tolerated, nor anything of a soft and porous nature, which might afford a harbour for insects. Bell-shaped cages, chiefly of wire, have been a good deal used; they are light and pretty, and easily kept clean. Perforated zinc has lately come into use as a material for cages; some good examples of its application to this purpose were shown in the Zollverein department of the Great Exhibition. Very elegant effects might be produced with this metal in combination with glass. Of this latter material, or of porcelain, food and water vessels should always be made; and their proper place is on the outside of the cage, the interior space of which ought to be at least a foot in height, eight inches in length, and about the same in breadth - that is, for one bird. Every cage should have at least two perches, at different heights, and these should not be placed one under the other. Breeding cages we have already spoken of.
