Fig. 30 shows a ground plan, and Fig. 31 :i cross section, of a plain style brooder house very commonly used. It is 13 ft. wide, and any length desired. The walk is excavated to a depth of iS inches, thus giving a passage along the north side of a house only 4i ft. high at the The walk is 3J ft. wide; the brooder 30 in. wide. Each pen is 5 X 7^ ft. The partitions between the pens is of board i ft., wire netting 2 ft., making the total height 3 ft. The partition between the pens and the walk is at the inner edge of the brooder. This brooder is really a long box containing, generally, four pipes — two flow and two return — connecting with hot water heater, placed in a pit several feet below the level of the floor, at one end of the house. (In verv long houses the heater is sometimes placed in the middle). At the end near the heater the pipes are about 4 in. from the floor. They rise gradually until, at the further end, they are 8 in. from the floor. They pass through holes bored at the proper height in each cross partition of the brooder, (the partitions of the brooder correspond to the pen partitions), and require no other supports. The top, or cover, of each section of the brooder i.« of matched boards held together with cleats, and lined on the under side with building paper. These covers are sometimes hinged ; sometimes rest on cleats nailed to the sides of the brooder. The side of the brooder next the %valk is a solid board. The side communicating with the pens is of woolen cloth with slits at short intervals to permit the chicks passing in and out. The pens nearest the heater, where the pipes are lowest, are used for the smallest chicks. As each hatch comes off" the whole lot of chicks is advanced one or more pens, being driven through small doors in the partitions betwe
