Note 646 — VIII CONCLUSION

"The process is in practice worked out as follows. First comes classification. The whole of the commodities known to commerce are entered on a list divided into classes, eight in number here, six in France, and about ten in number in the United States. To each class belongs a normal scale of rates, ranging, let us say, from ¾d. per mile in the lowest to 4d. per mile in the highest. The classification undoubtedly takes account of greater or less cost of carriage to the companies, arising out of the differences of packing, liability to theft or damage, proportion of space occupied to weight, etc. But it is safe to say that its main principle is, the more valuable the commodity, the higher the rate it can afford to pay."—Ibid., p. 325.
