F., while car C,in which salt had been added to the ice, not only cooled theoranges more quickly but reduced the average temperatureof the load to deg. F., a gain of 9 deg. F. as comparedwith car A. The amount of ice placed in the bunkers incar A, including that remaining in them at destination, wasapproximately 23,200 lb. In car B the ice amounted to18,675 lb., a saving of more than two tons. Car C, whichhad been salted, had 22,750 lb., still a little less than car results obtained with car C open up great possibilities. -~ig. 4 in the better distribution of such extremely perishable prod-ucts as strawberries, raspberries and cherries, widely pro-duced under conditions which generally preclude properprecooling before loading into the car. The insulated bulk-head prevented the frosting of the lading next to the bunker,and the floor rack provided a quick runway for the very coldair, which soon lost its temperature of 20 deg. F., or evenless, by the absorption of the heat of the lading and the results with the basket bunker, insulated bulkheadand floor rack, combined, naturally raise the question of therelative value of each of the three factors in producing andmaintaining circulation, and gaining the available refrigera-tion from the ice. Experimentation shows that a rack on thefloor of the car hastens the cooling of the load, and affordsverv decided protection to the lower layer of goods againstboth frost and heat. The floor rack alone, however, is farless effici
