ground, and yet is surrounded by earth, banked up against its stone walls. It is banked on three sides, leaving one side unbanked for entrance door and a window. The incubator room need not be large, so the labor of banking it in this way will not be great. Many are not able to secure a suitable place underground for a cellar, and for such the above plan will prove advantageous.

A Successful Incubator House, illustrated in Figure 65, is in use by an extensive woman poultry farmer, Mrs J. Fairbank, Oregon. It is a combination incubator cellar, water tank and windmill tower. The two

story building is fourteen by sixteen feet, with a one thousand-chick capacity hatching cellar, a tank in the second story which holds the water supply for the whole farm, and a windmill on the roof to perform all the pumping.

A double brooder house is shown in Figure 66, with walk in the center and pens on either side, and with heater at the end. Many prefer this plan to the single brooder house, as the care and attention required for the youngsters is much less and the cost of heating is reduced, one heater being sufficient for both lines of pipes. Then, again, this latter plan shortens the length

of the building by one-half and makes the work more concentrated.

Combined Brooder and Growing House-Figure 67 shows a successful plan for a combination building. The rows of brooder pens are at the right, while the large pens and yards are at the left. In a duck plant the right half of the buildings is used for the ducklings.

as soon as they are old enough to endure a lower temperature than that of the brooders. In a broiler plant, the use of the buildings may be similar, or the large pens may be used for laying stock.

The heater and feed room are between the two parts of the building, the heater being in a pit beneath the feed room. Pipes run into both parts of the build

ing, as shown by the dotted lines. The pipes in the right half of the building are raised two or three feet. from the floor, and a lower temperature is maintained. as compared with the brooders.

The brooder box (Figure 68) is next to the passageway, or walk, on each side, and runs the entire length of the building. This box is thirty inches wide and eight inches high; the sides are seven inches high and nailed securely; the top of the cover is nailed across with cleats to make it substantial, and the cover has an

inch strip nailed underneath in front and back to keep it in position. These strips rest against the seven-inch sides and make the brooder snug and tight when closed. The heating pipes are directly beneath the cover and are two-inch pipes, flow and return. Some prefer one-inch pipes, using two flows and two returns. When three pipes are used they should be about eight inches apart from center to center. These pipes rest on the partition boards of the pens. The front of the brooder, leading into the pens, is cut out in the center about four inches

deep and four feet long, while the ends and the other side are solid, being seven inches high. The construction of the brooder is clearly shown in b with cover removed, while c shows cover. The heater is located at the end of building.

A pipe brooder house, well liked at one of the eastern experiment stations, is shown in the combination drawing (Figure 69), in which dimensions and. interior construction are indicated. The hot water system is used, but the small lamp brooders may be used

if preferred. The heating pipes extend the length of the building under the covers, b b b. Through exit, c, the chicks reach a twenty-foot run inclosed with twofoot board and netting above. One of these houses will accommodate about five hundred chicks while small.

Houses for Single Brooders-These little buildings, described by C. E. Matteson of Wisconsin, are scattered over his place one hundred and fifty feet apart, so that one colony will not interfere with the other at feeding time, and each flock will go to its own house at night.
