I his undoubtedly is due to the goodcirculation obtained in the car. Comparative tests with theend ice box cars have shown that the Moore cars consumefrom 50 to 60 per cent less ice under the same Fig. 1. Moore Type Car There is no opportunity for the water from the melted iceto cause rotting and corrosion. The accompanying table, which is a report of a test madeon one of these cars, illustrates the even temperature main-tained throughout the car while under refrigeration.

By this means itis possible to carry from 20 to 25 per cent more freight in aMoore car than in an end ice box car of the same dimen-sions. The rigid construction of the ice box also provides avaluable reinforcement to the superstructure of the car. Apossible obje
