A third restriction that has fettered the exchange has been the geographical limitation imposed by many organizations. Many receive no consignments from outside the state, some New England exchanges limit consignments to that section, a few restrict consignments to residents of the city, and others, while having consigners in all parts of the country, congratulate themselves, as does one association, that “two thirds of the proportion of money paid out goes to the ladies of this city.” Still another exchange, on the Pacific coast, complains bitterly of the fact that articles have been sent to it by persons outside the state, and not dependent on their own labors for support, “but who would speculate upon the charitable spirit of the public,” and its president’s report recommends that it “prohibit exhibits from the East altogether.” This restriction undoubtedly grows out of the idea that the exchange is a dispenser of charity and should therefore aid first its own friends and neighbors. It is a spirit akin to that which in mediæval and even in modern times has resented the entrance of new workers into any occupation or community. But it must again be insisted that while the exchange is theoretically only a benevolent association, it is practically a business house, and as such must be judged by business principles. The most successful business firm that should adopt the policy of purchasing its supplies only within the state or city would soon find its trade decreasing, while for a new house to adopt the policy would be suicidal. Even the present high protective tariff is not so absolutely prohibitory as is this provision of many of the exchanges. Aside from other disadvantages, the plan prevents the infusion of new ideas so necessary to healthy growth, and it renders almost impossible that market criticism which secures the best industrial results. It is in distinct violation of that principle of commercial comity between states which led the framers of the Constitution to prohibit both import and export duties on all goods exchanged between the states, and to that extent is out of harmony with the recognized policy of the country regarding interstate exchange of commodities.
