The engineers have, indeed, succeeded in forming a real Brotherhood--a "feudal" brotherhood an opposing lawyer once called them--reëstablishing the medieval guild-paternalism so that each member is responsible for every other and all are responsible for each. They therefore merge themselves through self-discipline into a powerful unity for enforcing their demands and fulfilling their obligations. The supreme authority of the Brotherhood is the Convention, which is composed of delegates from the local subdivisions. In the interim between conventions, the authorized leader of the organization is the Grand Chief Engineer, whose decrees are final unless reversed by the Convention. This authority places a heavy responsibility upon him, but the Brotherhood has been singularly fortunate in its choice of chiefs. Since 1873 there have been only two. The first of these was P. M. Arthur, a sturdy Scot, born in 1831 and brought to America in boyhood. He learned the blacksmith and machinist trades but soon took to railroading, in which he rose rapidly from the humblest place to the position of engineer on the New York Central lines. He became one of the charter members of the Brotherhood in 1863 and was active in its affairs from the first. In 1873 the union became involved in a bitter dispute with the Pennsylvania Railroad, and Arthur, whose prompt and energetic action had already designated him as the natural leader of the Brotherhood, was elected to the chieftainship. For thirty years he maintained his prestige and became a national figure in the labor world. He died suddenly at Winnipeg in 1903 while speaking at the dinner which closed the general convention of the Brotherhood. When P. M. Arthur joined the engineers' union, the condition of locomotive engineers was unsatisfactory. Wages were unstable; working conditions were hard and, in the freight service, intolerable. For the first decade of the existence of the Brotherhood, strike after strike took place in the effort to establish the right of organizing and the principle of the collective contract. Arthur became head of the order at the beginning of the period of great financial depression which followed the first Civil War boom and which for six years threatened wages in all trades. But Arthur succeeded, by shrewd and careful bargaining, in keeping the pay of engineers from slipping down and in some instances he even advanced them. Gradually strikes became more and more infrequent; and the railways learned to rely upon his integrity, and the engineers to respect his skill as a negotiator. He proved to the first that he was not a labor agitator and to the others that he was not a visionary.
