all the world outside. Thus, for instance, Southern Classification territory is subdivided into local units, known, respectively, as the Southeastern Mississippi Valley Association, the Southeastern Freight Association, and the Associated Railways of Virginia and the Carolinas.[320] But for all practical purposes, so far as the larger problems of classification are concerned, our attention may be concentrated upon the three principal committees above mentioned. Some impression of the wide differences between these three main classifications in different parts of the country may be derived from the set of excerpts at the head of this chapter. In three parallel columns the alpha and omega of each are reproduced, together with bits of one of the most complicated schedules, viz., that dealing with agricultural implements. Even where the same commodities occur in each classification, the diversity in description, mode of packing, carload and other requirements, renders any direct comparison almost impossible. The mere fact that the class assignment, as shown at the right in each column, happens to be the same, as in the case of acetic acid in barrels or drums which moves both in Official and Southern Classification territory, third class in less-than-carload lots (_L. C. L._) and fifth class in carloads (_C. L._), shows nothing at all as far as equality of charges is concerned. For, as has been said, this is only half the statement of the rate. The spread between charges for different classes yet remains to be determined. The actual relativity between third-class and fifth-class rates, moreover, may be very different in the two places. In the New York Board of Trade case[321] this point was well exemplified. Comparative conditions as to rates in the three main sections of the country, as they then existed, were as follows: RATES IN CENTS PER HUNDREDWEIGHT Canned Class goods ------ ----------- Miles I. IV. L.C.L. C.L. New York to Chicago (Official class'n) 912 75 35 65 30 Chicago to Omaha (West'n class'n) 490 75 30 28.5 25 Louisville to Selma (South'n class'n) 490 98 63 63 52 On the trunk lines fourth-class rates were thus less than half those charged for the first class; in the West they were even lower, relatively; while in the South fourth-class rates were about two-thirds as high as the first-class rates. These differences in the spread between classes, as will be seen, interlocking as they do with a multitude of other considerations, are a serious bar to any partial modification in the direction of uniformity for the United States as a whole. Only by consideration of every factor entering into any given rate may comparisons safely be entertained.
