volume is the fruit had its origin in the preparation of a few notes for an anticipated location, and has since gradually expanded into a single magazine article, a short series of papers, and at last into a volume. Even the latter has been expanded far beyond the writer's original intention by the close and, it is to be feared, tedious attention to detail which he found continually more needful ; and it is kept within its present dimensions only by excluding considerable matter and superficially considering or neglecting altogether a number of subjects which thy writer deems of real importance for the correct conduct of location. In the improbable event that the sale of this volume should justify a thorough revision at some future day, he hopes to produce one more in keeping with the professional interest and importance of the subject, by rectifying the faults of omission and commission which he clearly perceives.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.13em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eThe writer does not intend to imply, however, that he has fallen into unacknowledged errors of fact or theory. All known errors have been frankly corrected as soon as discovered. For such others as may probably exist the writer can only hope that they will be regarded with that leniency which an exploration of a neglected field of labor may fairly ask. For such the present volume is, with all its imperfections. A recognition of the value of previous discussions of the same subjects would be a more welcome duty; but the writer deems it but simple justice to himself and his readers to declare frankly that, so far as his knowledge extends and he is competent to judge, all of the few existing discussions of the various leading topics of this volume are so superficial or so imperfect in method as to have little or no value as a guide for location. Some of them express correct views, and some of them will sometimes give correct results; but none of them are trustworthy, and several of those which are given under distinguished names are incredibly defective. The various problems of location, in fact, have been discussed or neglected by technical writers with an airy lightness which would convince an unskillful reader that they were either too simple, or too unimportant, or too well understood, for any careful analysis. And yet there is no field of professional labor in which a limited amount of modest incompetency, at $150 per month, can set so many picks and shovels and locomotives at work to no purpose whatever.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Calibri;font-size:1.13em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eAs a natural consequence of this general negligence, all our railways are uneconomically located, most of them in respect to their general route and system of gradients, and all of them in respect to the minor details of alignment, and in many cases these errors are shockingly evident. . . . In the care taken in this respect we are not advancing beyond, but rather falling below, the standard set up forty years ago, when the art of designing railways started out in this country with such brilliant promise. The works of Latrobe and Jervis and Thomson and Whistler show a truly remarkable ability, considering their early day, and bear the clearest marks of original and self-reliant thought : but the great men of that earlier day have no successors; for we have done nothing but copy them ill ever since, and a copyist is not a successor. We copy their errors, but we do not copy that admirable habit of personal investigation and far-sighted intellectual courage which created precedents, and has made the work of their hands-in despite of many faults-the high-water mark of American locating skill.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:left\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\n\u003cdiv style=\"text-align:left\"\u003e\u003cspan style=\"font-family:Arial;font-size:1.0em;color:#000000;font-weight:normal;font-style:normal;text-decoration:none;\"\u003eAll pictures are of the actual item.  There may be reflection from the lights in some photos.   We try to take photos of any damage.    If this is a railroad item, this material is obsolete and no longer in use by the railroad.  Please email with questions.
