. The principles of fruit-growing, with applications to practice. Fruit-culture. 420 The Principles of Fruit-growing. FiQ. 185. Combing ^cklng-house an^ storage-house in the Hood River Valley. A "medium-priced packing- and storage-house" in the Hood River country is illustrated in Fig. 185 (from Lewis and Brown, Ore. Bull. No. 118). It is provided with ventilator and a chute from the upper floors. The Alwood storage cellar, in Virginia, is shown in Fig. 186: The essential features involved in this storage-build- ing are: First, a cellar excavated into a gently sloping hillside, carried into the bank far enough to place the cellar-room entirely below the surface of the earth, and yet give opportunity to enter the cellar easily by an inclined way from the lower side of the slope; secondly, a flue leading out from near the center of the floor of the cellar-room, along the bank of the hillside for a considerable distance, with sufiicient fall to make it act both as a draiu-pipe and a fresh-air flue; thirdly, ventilating flues placed at each end of the cellar-room or elsewhere, as desired, and rising to the height necessary to give a sufficient draft to carry off rapidly the air from the cellar-room whenever ventilation is desired. If the air in the cellar becomes warmer than the air in the under- ground flue, it will rise through the ventilating flues, and the colder air will flow in from the supply flue, as desired. The temperature of the cellar-room can thus be approximately controlled to at least the neighborhood of 65° to 60° F. The two ventilators a a rise through the store-room, and are 6 inches in diameter by 15 feet long, thus insuring good draft. The air-flue b enters under the foundation and discharges fresh air into the cellar-room near the center. This flue is 6 inches in diameter, and theoretically should be extended far enough along the hillside to admit of tempering the air to the tem- perature of the surrounding earth while passing through it
