[Footnote: The principal political questions which agitated the country during this campaign were, (1) the Southern policy of the government, and (2) the civil service reform. It was held on one side that negroes and republicans at the South were intimidated by force and prevented from voting, and that the presence of the United States troops was necessary to the preservation of the rights of the citizens, free discussion, a free ballot, and an enforcement of the laws. It was asserted, on the other side, that the use of the troops for such purposes was unconstitutional; that the intimidation was only imaginary, or could be readily controlled by the local authorities; and that the presence of the military provoked violence and was a constant insult and menace to the States. President Jackson, as we have seen (p. 175), introduced into our politics the principle of "rotation in office." This policy steadily gained favor until Marcy's maxim, "To the victors belong the spoils," became the commonly-accepted view; and after every important election, the successful party was accustomed to fill even the menial offices of government with its favorites. Under such a system, the qualification of the applicant was of much less importance than the service he had done the party. Hayes promised to make "no dismissal except for cause, and no promotion except for merit."] HAYES'S ADMINISTRATION. (NINETEENTH PRESIDENT: 1877-1881.) DOMESTIC AFFAIRS.--_U. S. Troops at the South Withdrawn_. --President Hayes's Southern policy was one of conciliation. The troops which had hitherto sustained the republican State governments in South Carolina and Louisiana were withdrawn, and democratic officials at once took control of the local affairs. _A Railroad Strike_ was inaugurated by workmen on the Baltimore and Ohio Railroad in the summer of 1877. The cause was a reduction of wages by the managers of the different roads in the country. Seventy trains were stopped near Martinsburg, W. Va., and the blockade was raised only by the arrival of regular troops. The strike, however, rapidly extended to nearly all the principal railroads in the Northern States. Travel was suspended, and business came to a standstill. A tumult occurred in Baltimore, which was suppressed with some bloodshed. There was a terrible riot at Pittsburg, Pa., and cars, buildings, and an immense amount of property were destroyed, the loss of the Pennsylvania Railroad being estimated at $3,000,000. The troops at last quelled the disturbance, but at the cost of about one hundred lives. There were alarming riots also at Hornellsville, N. Y., at Chicago, Ill., at Louisville, Ky., and at Reading, Pa. These were suppressed, in part, by regular troops, but the militia generally proved reliable, and the citizen soldiery in this perilous crisis merited the gratitude of the republic. Quiet was finally restored, but the coal regions of Pennsylvania remained for a long time in disorder.
