The Milk Room
To economize space, the milk room, 12 × 16 feet, is located under the north driveway. The brick walls under the drive form the sides of this room, and the floor of the drive, which is made of 2 × 6s grooved on both edges, forms the roof. The grooves in the flooring were filled with white lead, and a wooden strip, fitted to fill the grooves of both planks, was driven in, forming a water-tight floor. This floor was covered with hot tar and sand 1⁄2 inch thick. The milk room is plastered on the inside, the plaster being applied directly to the brick walls, excepting in the case of the ceiling, which is lathed. The floor and cooling tank are of cement. The passage from the barn to the milk room is thru a small hallway, which is open to the outside, thus preventing the stable air getting into the milk room.
Fig. 22. Feed alley, showing combined hay chute and ventilator. A door on the side which is hinged at the bottom, 3 feet from the floor, is let in toward the silo, sliding the hay onto the floor. In hot weather this opening takes the heat out of the barn; During the winter this door is kept closed and the ventilation is regulated by raising the slide, as shown in the cut.
