To begin with, it will be well to take note of an estimate, made after a careful study of the figures, that fully eighty-five per cent of the fatalities that occur on our railroads can be directly traced to the negligence of employees. Regardless of the accuracy of this estimate, it certainly points to a very serious state of affairs. In studying the nature of these accidents and the conditions under which they take place, one cannot help being impressed with the fact that almost every possible way in which trouble can occur on a railroad is foreseen and provided for by some rule or safety device. So carefully has the ground been studied and worked over, that in every case of preventable accident it can almost be taken for granted that an employee is to blame. That is to say, the management of a railroad is always found to be impregnably protected by the rules and regulations from any direct responsibility. But, after all, this is only one side of the shield, for clearly the moral responsibility of a railroad manager cannot be said to cease with the printing of a batch of rules or the erection of a system of signals. It is not only necessary that rules should be plain and sufficient in themselves to prevent accidents, it is also equally essential that reasonable and systematic efforts should be exerted to enforce them. On a railroad, as elsewhere, the means employed for the supervision of personal conduct and for the enforcement of necessary rules are all included in the term discipline. Without some organized and effective system of discipline no industrial establishment of any kind can be successfully administered. On railroads in particular, the department of discipline is intimately related to the interests of the traveling public. Let us then examine in a practical manner the nature and methods of the discipline that is in force at the present day on what may be considered the most important railroad in New England. A little personal experience will throw the necessary light on the subject. [Illustration: A YARD WRECK]
