The natural growth of classification in a rapidly developing country like the United States, has manifested itself in three distinct ways: there has been a steady increase in the number of items of freight separately enumerated; a growing distinction in rates between carload and less-than-carload shipments; and a steadily enlarging volume of the most elaborate special rules and descriptions. As for the mere increase in distinct commodities enumerated, in the East in 1886 there had come to be about 1,000. The first Official Classification in the following year increased to 2,800 items; and by 1893, in the eleventh issue, there were twice that number. The latest Official Classification, No. 34 in 1909, contained approximately 6,000 separate enumerations--not many more, in fact, than fifteen years earlier. The point of saturation, or else the limit of human ingenuity, seems to have been about reached some years ago. The same thing was true of the Western Classification. In 1893 this contained 3,658 items, representing an increase of about 2,000 over the number of commodities classified by name in 1886. By 1909, as the above figures show, it comprehended 5,729, almost as many separate items, in fact, for less-than-carload lots as were recognized in trunk line territory. Only in carload ratings is the Western Classification less extensive. The Southern Classification reflected somewhat simpler trade conditions prevalent south of the Ohio river, by the relatively smaller number of articles enumerated; but it should be added that the number of exceptions--filling no less than 160 pages in the latest issue--is indicative throughout of a lesser degree of standardization than is found elsewhere. Perhaps the most striking feature of the southern system is the very small proportion of carload rates. But it should be noted in this connection that the basing point system afforded preference to market towns in any event; so that jobbers in such places did not need wholesale rates to the same degree. This phase of the matter will be elsewhere discussed.[326]
