It is only with the help of the railways that the provisioning of such vast collections of humanity as are to be found in London, Manchester, Liverpool, Birmingham, Glasgow and other centres is rendered possible. As compared with the earlier conditions of life, when households were mainly self-supporting, each providing for its own needs from its own fields, pasture or garden, the average urban family to-day is dependent on the trader for practically all domestic necessaries, and the same is mostly the case in suburban or even in country districts except, it may be, in regard to vegetables, eggs and table poultry. It is doubtful if London or any other of these great centres ever has more than, at the outside, a fortnight's supplies on hand. The complete stoppage of the railway system for any such period would thus be a national disaster. Food might still come to the ports in the same quantities as before; but without the railways there would be no adequate means for its distribution, and the large inland towns would more especially be at a disadvantage. The mere possibility of such an eventuality may help one to realise the extent of our dependence to-day on rail transport from the point of view, not alone of trade, industry and commerce, but of our daily life and sustenance.

While it is true that many rural centres suffered a decline in population when the railways led indirectly to so many agricultural workers leaving the fields for the attractions and the supposed advantages of urban life, it is no less true that the expansion of the towns gave to those who remained in the rural centres greater markets for the sale there of such produce—and especially for such market-garden produce, eggs and poultry—as they could supply to advantage. The railways may not have annihilated distance, but they were engaged in curtailing distances; and such curtailment became still more effective when the achievements of the locomotive were followed by the adoption of the sliding-scale principle under which the rates per ton per mile decreased in proportion as consignments were sent for a greater distance than twenty miles.

The towns and the industrial centres expanded further as rail transport afforded increased facilities for the conveyance of raw materials to works which, thanks to the steam-engine, could be set up in any part of the country, regardless of the once indispensable water power; and the procuring of these raw materials not only gave a further great expansion to national wealth, but led to the opening up to industrial activity of many a district previously isolated and undeveloped.

Increased congestion in the towns was thus none the less supplemented by a widespread development of the interior resources of the country; and in this respect the railways accomplished results that could not have been attained by the most complete system either of canals or of turnpike roads. There certainly were losses, besides those in the rural districts, and this was notably the case in some of the county, market, or smaller towns which no longer command the same distinction in the social and economic world as before; but the balance as between gains and losses was in favour of an industrial expansion, a commercial development, and an unexampled increase in general prosperity.

On the general trade of the country the railway was to produce results no less striking than those that related to individual industries.

When the facilities for distributing domestic and other necessaries throughout the inland districts, and even in the most remote parts of the country, were so greatly increased, the reason for the fairs which had for many centuries played so all-important a part in English trade and commerce no longer existed, and the country hastened to deserve Napoleon's sarcasm by becoming "a nation of shopkeepers."

To the country trader the railway gave new opportunities. There was no longer any need either for his going to one of the periodical fairs or for his awaiting a call from a travelling middleman with his troop of packhorses in order to obtain supplies. Nor was it now necessary for him to purchase comparatively substantial quantities of wares at a time. Thanks to the railway, he could generally have goods sent to him direct from the manufacturer or the warehouseman in London, Manchester, Sheffield, Glasgow or elsewhere, and those goods, sent for one day and delivered the next, could be ordered by him in exactly such quantities as would suit his immediate requirements. In this way he was enabled to keep smaller stocks of a greater variety of articles, trade with less, or with better distributed, capital and anticipate a much larger turnover. The advantage of these facilities became greater still in proportion as the post, the telegraph and the telephone gave the retailer greater opportunities for communicating his wants to the wholesale trader who supplied them.

In these circumstances village stores are to be found to-day in rural districts where shops had been non-existent down to the Railway Age, while the conditions of retail trade in probably every country town have no less changed, and have altered to a proportionate extent the conditions, also, of wholesale trade.

On the other hand, the same transport facilities which gave these opportunities to the small trader are now, to a certain extent, operating to his disadvantage, since there is an increasing tendency for retail trade to be done by the large houses which are to-day more and more dealing direct with the public, consigning to retail customers either by rail or by parcel post. In this way many of the small traders are sharing the fate of the small masters who had already been suppressed by the factory system.

The movement here in question is, of course, only a development of the dual tendency now prevalent throughout the commercial world for (1) the substitution of large or associated undertakings for numerous small and independent ones; and (2) the abolition of middlemen; yet such a movement could hardly have been carried out to its present actual extent but for the opportunities offered by the railway for the regular, speedy and economical transport of commodities under just such conditions as will alone allow of this further transition in trade being brought about.
