. Better fruit. Fruit-culture. o^fiTFORM SKETCHED â /frv/5ro plfin or D fly 15 EVAPORATOR ruci. pl irrof^M tunnel cars to transfer car, and vice versa. Depth about 2 inches. 5. Tunnel floor and ceiling slope ^4 inch per foot from fan toward furnace end of tunnel to facilitate moving loaded cars forward. 6. One side sliding door at side of tunnel 10 inches from fan end and a similar door at side of tunnel 6 inches from end of tunnel. Doors to be 7 feet 1 inch high and 6V2 feet wide and of double thickness T. & G. flooring. 7. Air return flue 6V2 feet wide by 1 foot high and 33 feet long above tunnel. Ceiling of tunnel forms floor of this flue. Walls and ceil- ing of flue of T. & G. flooring over 2x4 S-2-S Oregon pine. Fan end of flue connected to air outlet of top vertical discharge fan by sheet metal housing fitted with adjustable sliding door. Opposite or furnace end fitted with adjustable folding door. 8. Fan. Outlet end of tunnel connected to a stop vertical discharge multivane exhaust fan of such size that its catalog rating is about 18,000 cubic feet of air at 300 and 'A-inch static pressure, corresponds to a No. 6 Sirocco fan or No. 9 Sturtevant multivane ex- haust fan. 9. Motor. A 71 motor or engine is needed to operate the fan, which should be fitted with such size pulley as to give about 300 to fan. A 23-inch pulley on fan and 6-inch pulley on a motor operating at 1180 will give about the desired speed. 10. Tracks. Transfer tracks through each tunnel door of 8 pounds per yard dry yard rails set in concrete on 4x4-inch ties. Rails 42 inches apart. One set 20 feet long and other set 31 feet long, latter connecting with sulphur house. Tracks in tunnel extending between the two sets of transfer tracks of 8 pounds per yard rails set 24 inches apart inside in con- crete on 4xl-inch ties and are 27 inches from walls inside of rails. Rails extend to edge of transfer car pits at each end of tunnel and are 20 feet 10 inches long.
