Immigration, another constant factor in American development, underwent important changes during the twenty-five years from 1865 to 1890. Greater in prosperous years and smaller during years of depression, the inward tide reached its climax in 1882, when 789,000 aliens reached the new world. That year, in several respects, was a turning point in the history of immigration into the United States. It was in this year that the Chinese were excluded; that immigration from Italy, Austria-Hungary, and Russia became of sufficient size to be impressive; and that the first inclusive federal immigration act was passed. The immigration law of 1882 defined, in general, the policy which the nation has pursued ever since. It placed a tax of fifty cents on all incomers to be paid by the ship companies; it forbade the landing of objectionable persons, such as convicts and lunatics; and it placed on the owners of vessels the expense of returning immigrants not permitted to land. All these provisions were amended or developed in later laws, like that of 1885 forbidding persons or corporations to prepay the transportation of laborers or to encourage immigration under contract to perform work. The greater part of the foreign population settled in the manufacturing and urban North. Put into simplest terms, the census of 1890 showed that of every hundred aliens who had come to the United States between 1870 and 1890, thirty-seven were to be found in the states from Maine to Pennsylvania, four from Delaware to Texas, forty-seven from Ohio to Kansas and twelve in the Far West (for the most part Chinese). Of the great economic interests of the United States, the most widespread was agriculture. In the Northeast, to be sure, the amount of improved farm land had been growing steadily less since 1850 and the people had been turning their energies into other activities. In the South, on the other hand, agriculture formed the main economic resource and the twenty-five years following the war were, for the most part, consumed in recovering from that struggle. Although conditions varied from place to place, the situation in many portions of the South was little short of pitiable. Not only were factories, public buildings and railroads, houses and barns, tools and seeds destroyed, capital and credit gone, mining at a standstill and banks ruined, but bands of thieves infested many districts, federal officers were frequently dishonest and defrauded the people, and the entire labor system was wiped out at a stroke. The negroes had not been ideal workmen as slaves; now, as freedmen, they found difficulty in adjusting themselves to the economic obligations of their new status, and evinced a tendency to rove about restlessly, instead of settling down to the stern task of helping to rebuild the shattered South.
