A very large and expensive bridge is like an important mountain pass, differing only in that one is the gift of Nature, while the other is wholly the work of man. But because the latter is the work of man, it does not follow that it is not a monopoly. The great bridge across the Mississippi River at St. Louis is owned by a private company which levies tolls for the teams and trains passing over it. These are deemed excessive, as they are sufficient to pay an exorbitant interest on the cost of the bridge. Yet for many years no one has cared to invest money in the erection of a new bridge, for they saw that there was no more traffic than one bridge could readily carry, and they knew that if a new bridge were erected, in the rivalry in tolls which would ensue, the old-established company would probably bankrupt its rival. It is thus plainly seen how an important bridge may become a monopoly, and a most powerful and onerous one. We have still one important monopoly of communication to describe, the telegraph. Viewed from a narrow standpoint it may be thought that there should be no monopoly in the telegraph. A telegraph line is not expensive to erect and maintain, and it gets no monopoly from taking advantage of the most favorable route through difficult country as a railway does. But the economy effected by combination and the effect of sharp competition in bringing about bankruptcy and then consolidation are exactly similar to the case of the railway, which we have just described. In the early history of telegraph companies, many short competing lines struggled and fought for supremacy. In 1859 the Western Union Telegraph Company was formed with the avowed intention of combining these warring companies and making the telegraph business profitable. It has exceeded the most sanguine dreams of its promoters by swallowing up its rivals until the entire system of telegraph communication of the country is practically in its hands. The effects of this consolidation have been of two sorts. On the one hand we have the telegraph service of the country performed with the least possible work; there is nothing wasted in the maintenance of two or more rival offices in small towns where one is sufficient, nor in operating two lines of wire where a single one would serve as well. All expense of "drumming up" business in various ways is avoided, and also the cost of keeping the complicated books necessary when the receipts of a single message must be divided among several companies. On the other hand it is plain that the public is wholly at the mercy of the monopoly in the matter of rates, and must pay for the use of the telegraph exactly what the corporation asks. There is a weak and foolish argument which is often used in an attempt to show that this particular monopoly is not hurtful. It is that the telegraph is a luxury which only wealthy people use, and hence whether its rates are high or low is of little account. The
