In Belgium and in Switzerland one may buy the equivalent of a card-pass upon an American railroad, good for a week or a fortnight or a month, according to the price paid. During the extent of its life it is good for unlimited travel by the person whose photograph it bears. The French have an even better system. For a matter of five or six hundred francs one purchases a similar card which for the ensuing twelvemonth gives the right, not for unlimited travel, but for the purchase of an unlimited number of tickets at one-half the regular prices; after which, for the holder of the card, the game inevitably becomes one of buying enough separate tickets to beat the first prices put down for the card. Transportation salesmanship? Properly played it is one of the most subtle games in the world, and one of the most fascinating--and for the railroad, one of the most profitable. * * * * * We have seen a good deal in the public prints in the last few years about the prime necessity of nationalizing the railroad in the United States in a far more thorough fashion than has ever before been even attempted. One of the potential dangers which forever faces a land as physically great as ours is the inherent possibility of its falling apart through its sheer size and weight. Under certain circumstances it might not be particularly difficult for us to disintegrate as a nation into groups of separate States, in fact if not in name--groups of States not particularly sympathetic or cooperative. We have had in our history already one very tragic instance of this very sort. In order that this ever-present potential tendency may be overcome it is highly important that every possible measure be utilized toward binding the country more and more closely together. Transportation--railroad transportation in particular--forms an ideal binder. Utilized to its fullest degree it means that New England will know California better, and California New England. And each, knowing the other better, will understand better, sympathize better, cooperate better. If Minnesota goes to Louisiana and Georgia to Montana, each becomes more understanding, more tolerant, more closely bound, in almost every conceivable fashion. Passenger traffic, brought to a high degree of development, will make such understanding possible. Little else can do it even half so well. Freight traffic will not do it--not at least to any particularly large degree. A better circulation of national periodicals will help; this ever-present problem of encompassing our perplexing problem of nationalization, of making a group of forty-eight separate States, separate in climate, in soil, and even to a perceptible degree in racial and language characteristics, into a more coherent and closely-knit state, was one of the most potent arguments advanced against the introduction of the postal zone system in this country.
