THE ROLLER CANARY 49 
The Training Cage shown on page 50, and also the 
Cabinet, can be made with any kind of wood to the 
given sizes, but hard wood, like pitch pine, is preferable, 
and, when varnished, this will have a very neat appear-

moult, place the cocks in the cages, being careful to place 
the ring numbers on the cabinets, for this will enable 
you to find any particular bird by referring to your stock 
book. 
A VALUABLE SUGGESTION 
After placing the birds in the cabinets, leave the doors 
open at first to make sure they find their feeders and 
drinkers, and let the doors remain open for at least two 
days. On the third day close one door, the following 
day partly close the next door, and the succeeding day 
close all up. 
Be sure you have plenty of fresh air in the room in 
which you are going to keep them. Open the cabinets, 
and give fresh food and water the first thing every morn- 
ing, and leave the cabinets open for an hour. Open the 
doors again at noon for half an hour, and then close 
until evening. 
When you hear one or more of your young birds 
singing in the darkness open the doors immediately 
and let them sing their song. Listen very critically 
for any bad faults, and when they are finished close 
the doors. 
The song box I use is a roomy one, with three holes 
at the back about 1% in. in diameter, and the doors are 
so constructed that when closed there is a space of about 
one-eighth of an inch at each side, allowing of the
