It was estimated in 1860, on the basis of the census figures, that mechanical production gave employment to 1,100,000 men and 285,000 women, making, if the average number of dependents upon them be reckoned, nearly six million people or about one-sixth of the population of the country sustained from manufactures. "This," runs the official record, "was exclusive of the number engaged in the production of many of the raw materials and of the food for manufacturers; in the distribution of their products, such as merchants, clerks, draymen, mariners, the employees of railroads, expresses, and steamboats; of capitalists, various artistic and professional classes, as well as carpenters, bricklayers, painters, and the members of other mechanical trades not classed as manufactures. It is safe to assume, then, that one-third of the whole population is supported, directly, or indirectly, by manufacturing industry." Taking, however, the number of persons directly supported by manufactures, namely about six millions, reveals the astounding fact that the white laboring population, divorced from the soil, already exceeded the number of slaves on Southern farms and plantations.

Immigration.—The more carefully the rapid growth of the industrial population is examined, the more surprising is the fact that such an immense body of free laborers could be found, particularly when it is recalled to what desperate straits the colonial leaders were put in securing immigrants,—slavery, indentured servitude, and kidnapping being the fruits of their necessities. The answer to the enigma is to be found partly in European conditions and partly in the cheapness of transportation after the opening of the era of steam navigation. Shrewd observers of the course of events had long foreseen that a flood of cheap labor was bound to come when the way was made easy. Some, among them Chief Justice Ellsworth, went so far as to prophesy that white labor would in time be so abundant that slavery would disappear as the more costly of the two labor systems. The processes of nature were aided by the policies of government in England and Germany.

The Coming of the Irish.—The opposition of the Irish people to the English government, ever furious and irrepressible, was increased in the mid forties by an almost total failure of the potato crop, the main support of the peasants. Catholic in religion, they had been compelled to support a Protestant church. Tillers of the soil by necessity, they were forced to pay enormous tributes to absentee landlords in England whose claim to their estates rested upon the title of conquest and confiscation. Intensely loyal to their race, the Irish were subjected in all things to the Parliament at London, in which their small minority of representatives had little influence save in holding a balance of power between the two contending English parties. To the constant political irritation, the potato famine added physical distress beyond description. In cottages and fields and along the highways the victims of starvation lay dead by the hundreds, the relief which charity afforded only bringing misery more sharply to the foreground. Those who were fortunate enough to secure passage money sought escape to America. In 1844 the total immigration into the United States was less than eighty thousand; in 1850 it had risen by leaps and bounds to more than three hundred thousand. Between 1820 and 1860 the immigrants from the United Kingdom numbered 2,750,000, of whom more than one-half were Irish. It has been said with a touch of exaggeration that the American canals and railways of those days were built by the labor of Irishmen.

The German Migration.—To political discontent and economic distress, such as was responsible for the coming of the Irish, may likewise be traced the source of the Germanic migration. The potato blight that fell upon Ireland visited the Rhine Valley and Southern Germany at the same time with results as pitiful, if less extensive. The calamity inflicted by nature was followed shortly by another inflicted by the despotic conduct of German kings and princes. In 1848 there had occurred throughout Europe a popular uprising in behalf of republics and democratic government. For a time it rode on a full tide of success. Kings were overthrown, or compelled to promise constitutional government, and tyrannical ministers fled from their palaces. Then came reaction. Those who had championed the popular cause were imprisoned, shot, or driven out of the land. Men of attainments and distinction, whose sole offense was opposition to the government of kings and princes, sought an asylum in America, carrying with them to the land of their adoption the spirit of liberty and democracy. In 1847 over fifty thousand Germans came to America, the forerunners of a migration that increased, almost steadily, for many years. The record of 1860 showed that in the previous twenty years nearly a million and a half had found homes in the United States. Far and wide they scattered, from the mills and shops of the seacoast towns to the uttermost frontiers of Wisconsin and Minnesota.

The Labor of Women and Children.—If the industries, canals, and railways of the country were largely manned by foreign labor, still important native sources must not be overlooked; above all, the women and children of the New England textile districts. Spinning and weaving, by a tradition that runs far beyond the written records of mankind, belonged to women. Indeed it was the dexterous housewives, spinsters, and boys and girls that laid the foundations of the textile industry in America, foundations upon which the mechanical revolution was built. As the wheel and loom were taken out of the homes to the factories operated by water power or the steam engine, the women and, to use Hamilton's phrase, "the children of tender years," followed as a matter of course. "The cotton manufacture alone employs six thousand persons in Lowell," wrote a French observer in 1836; "of this number nearly five thousand are young women from seventeen to twenty-four years of age, the daughters of farmers from the different New England states." It was not until after the middle of the century that foreign lands proved to be the chief source from which workers were recruited for the factories of New England. It was then that the daughters of the Puritans, outdone by the competition of foreign labor, both of men and women, left the spinning jenny and the loom to other hands.

The Rise of Organized Labor.—The changing conditions of American life, marked by the spreading mill towns of New England, New York, and Pennsylvania and the growth of cities like Buffalo, Cincinnati, Louisville, St. Louis, Detroit, and Chicago in the West, naturally brought changes, as Jefferson had prophesied, in "manners and morals." A few mechanics, smiths, carpenters, and masons, widely scattered through farming regions and rural villages, raise no such problems as tens of thousands of workers collected in one center in daily intercourse, learning the power of coöperation and union.

Even before the coming of steam and machinery, in the "good old days" of handicrafts, laborers in many trades—printers, shoemakers, carpenters, for example—had begun to draw together in the towns for the advancement of their interests in the form of higher wages, shorter days, and milder laws. The shoemakers of Philadelphia, organized in 1794, conducted a strike in 1799 and held together until indicted seven years later for conspiracy. During the twenties and thirties, local labor unions sprang up in all industrial centers and they led almost immediately to city federations of the several crafts.

As the thousands who were dependent upon their daily labor for their livelihood mounted into the millions and industries spread across the continent, the local unions of craftsmen grew into national craft organizations bound together by the newspapers, the telegraph, and the railways. Before 1860 there were several such national trade unions, including the plumbers, printers, mule spinners, iron molders, and stone cutters. All over the North labor leaders arose—men unknown to general history but forceful and resourceful characters who forged links binding scattered and individual workers into a common brotherhood. An attempt was even made in 1834 to federate all the crafts into a permanent national organization; but it perished within three years through lack of support. Half a century had to elapse before the American Federation of Labor was to accomplish this task.

All the manifestations of the modern labor movement had appeared, in germ at least, by the time the mid-century was reached: unions, labor leaders, strikes, a labor press, a labor political program, and a labor political party. In every great city industrial disputes were a common occurrence. The papers recorded about four hundred in two years, 1853-54, local affairs but forecasting economic struggles in a larger field. The labor press seems to have begun with the founding of the Mechanics' Free Press in Philadelphia in 1828 and the establishment of the New York Workingman's Advocate shortly afterward. These semi-political papers were in later years followed by regular trade papers designed to weld together and advance the interests of particular crafts. Edited by able leaders, these little sheets with limited circulation wielded an enormous influence in the ranks of the workers.

Labor and Politics.—As for the political program of labor, the main planks were clear and specific: the abolition of imprisonment for debt, manhood suffrage in states where property qualifications still prevailed, free and universal education, laws protecting the safety and health of workers in mills and factories, abolition of lotteries, repeal of laws requiring militia service, and free land in the West.
