COLD STORAGE WAREHOUSES (VENTILATION OF) Fruit and vegetables are alive until they begin to decay and if they . j to remain alive and well they must be given an ample supply of air d favorable humidity conditions. Conclusive demonstration has been ide of the necessity of controlled ventilation for rooms in which fruit d vegetables are stored, even though the temperature in such rooms ay be kept very low. It is possible to obtain well developed proprietary stems of ventilation for cold storage warehouses, and as the volume air to be changed may be comparatively small, the cost for extra frigeration due to ventilation is trifling, and often is more than comsnsated for by the improved interior air circulation and the elimination f Waiar-rsethroautisfiecsaftoiornf.ruit storage where no refrigeration is employed should ave many doors and windows, which may be opened during the night `L`" --A 'icwseH during the day.
