RAILWAY TRANSPORTATION 513 has been a marked increase in the tonnage of manufactures and mis- cellaneous traffic (in car-lots) since pre-war years. The volume of products of mines and of manufactures loaded during 1925 was greater than in 1924, the latter making a new high record. The other com- modity groups show a decrease, most marked in the case of agricul- tural products.

Source: Interstate Commerce Commission Car Loadings—Surpluses and Shortages. The total number of cars loaded (revenue freight) during 1925 was 51,178,000, greater than in 1924 by 2,644,000, or 5.4 per cent, and the greatest in the history of the railroads (Table 7). During the third quarter of 1925 the car loadings exceeded those of any previous quar- ter, while even the last quarter surpassed the highest quarter in any previous year (third quarter of 1923). In Table 6 average weekly car loadings are shown by quarters, the original statistics being based on weeks rather than months to avoid the effect of varying length of the months. Car shortages were practically nil in 1925 except for the last quarter, during which there was a very slight shortage of certain classes of equipment. Although figures of car surpluses and shortages are not entirely satisfactory as an index to the carriers’ capacity to take care of traffic requirements, they present an approximate picture of the situation. Frequently shippers order more cars than are needed during a shortage period in the hope of thus getting their minimum 1950-——98+—— ©
