All reasons, therefore, combined to direct the first movement of the United States upon Cuba, and upon Cuba alone, leaving Spain in undisputed possession of such advantages as Puerto Rico might give. But Cuba and Puerto Rico, points for attack, were not, unluckily, the only two considerations forced upon the attention of the United States. We have a very long coast-line, and it was notorious that the defences were not so far advanced, judged by modern standards, as to inspire perfect confidence, either in professional men or in the inhabitants. By some of the latter, indeed, were displayed evidences of panic unworthy of men, unmeasured, irreflective, and therefore irrational; due largely, it is to be feared, to that false gospel of peace which preaches it for the physical comfort and ease of mind attendant, and in its argument against war strives to smother righteous indignation or noble ideals by appealing to the fear of loss,--casting the pearls of peace before the swine of self-interest. But a popular outcry, whether well or ill founded, cannot be wholly disregarded by a representative Government; and, outside of the dangers to the coast,--which, in the case of the larger cities at least, were probably exaggerated,--there was certainly an opportunity for an enterprising enemy to embarrass seriously the great coasting trade carried on under our own flag. There was much idle talk, in Spain and elsewhere, about the injury that could be done to United States commerce by scattered cruisers, commerce-destroyers. It was overlooked that our commerce under our own flag is inconsiderable: there were very few American ships abroad to be captured. But the coasting trade, being wholly under our own flag, was, and remains, an extremely vulnerable interest, one the protection of which will make heavy demands upon us in any maritime war. Nor can it be urged that that interest alone will suffer by its own interruption. The bulky cargoes carried by it cannot be transferred to the coastwise railroads without overtaxing the capacities of the latter; all of which means, ultimately, increase of cost and consequent suffering to the consumer, together with serious injury to all related industries dependent upon this traffic.
