When railroads are built where they are needed, at the time they are wanted, in a country able to support them, by permanent investors, and not by speculators, and are well made by good engineers, and well managed by competent men, whose interest is really connected with the success of the enterprise, then they will pay, and be railroads indeed. But so long as money is obtained on false pretences, to be played for by State and Wall Street gamblers on the one hand, and ravenous contractors on the other hand, they will be what they are,--worthless monuments of extravagance and folly. "Experience keeps a dear school," says poor Richard, "but fools will learn in no other." Let not the reader think for a single moment that we have no appreciation of the labors of a De Witt Clinton, or of a Livingston, --that we at all underrate the services of the Eastern capitalists who render available the public-land grants of the West, whether to build ship-canals or railroads. We have the highest respect for that talent without which our Western lands would still be left to the buffalo and the deer, and the gold and silver of Europe would remain on the other side of the Atlantic. These capitalists are the mainsprings of the system; but we should no more apply their energy and skill to the detailed operation of so mechanical a structure as a railroad, than we should attach the mainspring of a watch to the hands directly, without the intermediate connecting chains and wheels. Not less incompetent for the construction of railways, than are the directors for the management of the completed roads, are at least one half of the so-called engineers in America. Obliged to complete no course of education, to pass no examination, they are at once let loose upon the country whenever they feel like it, to build what go by the names of railroads and bridges, but are in reality traps in which to lose both life and money. Indeed, any man (in the United States) who has carried a rod or chain is called an engineer; while the correct definition is, a man who has, first, a thorough knowledge of mechanics, mathematics, and chemistry,--second, the knowledge necessary for applying these sciences to the arts,--and last, the knowledge requisite to the correct adaptation of such arts to the wants of man, but more than all, that experience which is got only from continual practice. We have such a class of engineers, and to them we owe what of fame we have in the engineering world. Second, comes another grade, men who, commencing as subordinates, without any preparatory knowledge, but with natural genius, and an intuitive knowledge of mechanics, need only to have their ideas generalized to see the bearing of their special knowledge upon the whole, in order to rank high in the profession. Third, a class who lack both natural and acquired knowledge, and whose only recommendation is that they are always for sale to the highest bidder, whether he be president,
