Cages and Cage-making. 45 



The space between the stay and bar is wired with stout 

 wires, set lin. apart; this is where the birds feed through. 

 Above this is a piece of glass extending from the cross-bar 

 to the lid of the hopper, and this forms the front of it, 

 and enables you to see when a further supply of seed is 

 required. Inside of the hopper is fixed a piece of thin wood 

 the entire length of the front; it extends from the cross-bar, 

 which supports the glass, to within fin. of the back, and is 

 placed at an acute angle, and l^in. from the bottom of the 

 hopper or feeding-box. This forms the aperture for the seed 

 to fall through ; and so long as there is a supply of seed

in the upper portion or box the lower portion or feeding- 

 trough is kept constantly supplied by this contrivance. A 

 small hole should be made in that portion of the back which 

 projects above the lid, to hang it up by. The lid is made of 

 wood and secured with two pieces of wire, which act like 

 hinges. The illustration fully explains anything further that 

 is required to be known. The hopper should be made of wood 

 from in. to fin. in thickness when dressed ready for use. 



Figs. 30 and 31 are made of wood with glass cover or 

 front, arranged to slide in and out of grooves made at each 

 side with a stout hand-saw. They are so constructed as to 

 fit close to the cage front, with the object of preventing mice
