The war brought this development to a stand-still for the time being; but it was afterward resumed with renewed vigor. It is probable that the final effect of the war was to hasten rather than to retard the growth of large systems. In the first place, it familiarized men's minds with national ideas instead of those limited to their own State. It is hard for us to realize that our business ideas were ever thus confined by artificial boundaries; but if we wish proof, we have only to look at the original location of the Erie Railway from Piermont to Dunkirk. Both were unnatural and undesirable terminal points; but people were willing to submit to inconvenience and to actual loss in order that the railroad might run as far as the New York State limits would allow, and not one whit farther. Similar instances can be found in other States. Hard as it is to understand, there seems to have been a positive jealousy of interstate traffic. The war did much to remove this by making the different sections of the country feel their common interest and their mutual dependence. It also had more direct effects. It produced special legislation for the Pacific railroads as a measure of military necessity; and this was but the beginning of a renewal of the land-grant policy, no longer through the medium of the States, but in the Territories and by the direct action of Congress. All the results in the way of extension or consolidation which had been noted in the first land-grant period were more intensely felt in the second. Never was there a time when business foresight and administrative power were more needed or more richly rewarded than in railroad management during the third quarter of the century. [Illustration: J.
