My Aviary and Its Inmates. 101 
is hi^'h in summer it is not too hot inside. The south side is glass 
for about seven feet from the ground, so that a sun parlour is 
available in winter. 
Inside the house is a passage way about four feet witle 
which runs straight through from end to end. From this the 
flights— and there are ten of them— are divided off by ordinary § 
wire. The flights resemble stalls, each being 5 ft. x 8 ft. x 12 ft. 
high. They are dividetl with wood up to a height of about seven 
feet, and from there to the roof the f wire is used. The wood is 
set in a slot like the door of a coal bin, so that two flights can be 
easily made into one if it should be found desirable. 
I used 1 wire so that mice cannot get through it and they 
can through ^-inch wire. In each flight there is a door. It is pur- 
posely made low — about \t, feet in height — and at the side of the 
door is a box jutting out about eight inches into the passage way. 
It is 2 ft. () in. high by 4 ft. G in. long, divided by a l)oard in the 
middle, so that the same box runs from one flight to the one ad- 
joining. The cover is hinged and divided in two, and by raising 
these covers the food can be placed in the flights without opening 
the doors. 
I have found this arrangement very satisfactory. If I had 
it to do over again the only improvement I could suggest would 
be to make a metal tray, like the tray of a bird cage, at the l)ottom 
of each box. 
There is a one-inch water-pipe running lengthwise through 
the middle of the flights, and in the centre of each flight is a tee 
from which a one-half-inch pipe comes up through the floor to a 
height of about four inches. The toj) of this short half-inch con- 
nection is threaded, and after it had l)een slit with a hack saw, I 
screwed on each one an ordinary half-inch cap. I found that I 
could adjust the flow of water by the distance I screwed the cap 
down, and that the spray was forced directlj downward. 
Another hole was made through the floor, close to the inlet, 
and a one-inch coupling set flush with the Ijottom of the basin. 
In this a short piece of pii)e al)out two and a half inches long is 
screwed loosely. If it is removed all the water washes away, and 
if left in it will not rise above its level. 
My basins are made of concrete. I had a plumber make 
two galvanized iron hoops for a mould — the larger about 1 foot 8 
inches in diameter by 5 inches high, and the smaller 1 foot G
