The Slavs, too, wedge into the most surprising spaces. Their colonies and settlements are to be found in considerable numbers in every part of the Union except the far South. They are on the cut-over timber lands of Michigan, Wisconsin, and Minnesota, usually engaged in dairying or raising vegetables for canning. On the great prairies in Iowa, Nebraska, Kansas, and the Dakotas, the Bohemians and the Poles have learned to raise wheat and corn, and in Texas, Oklahoma, and Arkansas, they have shown themselves skillful in cotton raising. Wherever fruit is grown on the Pacific slope, there are Bohemians, Slavonians, and Dalmatians. In New England, Ohio, Illinois, Indiana, and Maryland, the Poles have become pioneers in the neglected corners of the land. For instance in Orange County, New York, a thriving settlement from old Poland now flourishes where a quarter of a century ago there was only a mosquito breeding swamp. The drained area produces the most surprising crops of onions, lettuce, and celery. Many of these immigrants own their little farms. Others work on shares in anticipation of ownership, and still others labor merely for the season, transients who spend the winter either in American factories or flit back to their native land.

In Pennsylvania it is the mining towns which furnished recruits for this landward movement. In some of the counties an exchange of population has been taking place for a decade or more. The land dwelling Americans are moving into the towns and cities. The farms are offered for sale. Enterprising Slavic real estate dealers are not slow in persuading their fellow countrymen to invest their savings in land.

The Slavonic infiltration has been most marked in New England, especially in the Connecticut Valley. From manufacturing centers like Chicopee, Worcester, Ware, Westfield, and Fitchburg, areas of Polish settlements radiate in every direction, alien spokes from American hubs. Here are little farming villages ready made in attractive settings whose vacant houses invite the alien peasant. A Polish family moves into a sedate colonial house; often a second family shares the place, sometimes a third or a fourth, each with a brood of children and often a boarder or two. The American families left in the neighborhood are scandalized by this promiscuity, by the bare feet and bare heads, by the unspeakable fare, the superstition and credulity, and illiteracy and disregard for sanitary measures, and by the ant-like industry from starlight to starlight. Old Hadley has become a prototype of what may become general if this racial infiltration is not soon checked. In 1906 the Poles numbered one-fifth of the population in that town, owned one-twentieth of the land, and produced two-thirds of the babies. Dignified old streets that formerly echoed with the tread of patriots now resound to the din of Polish weddings and christenings, and the town that sheltered William Goffe, one of the judges before whom Charles I was tried, now houses Polish transients at twenty-five cents a bed weekly.

The transient usually returns to Europe, but the landowner remains. His kind is increasing yearly. It is even probable that in a generation he will be the chief landowner of the Connecticut Valley. It will take more than an association of old families, determined on keeping the ancient homes in their own hands, to check this transformation.

The process of racial replacement is most rapid in the smaller manufacturing towns. In the New England mills the Yankee gave way to the Irish, the Irish gave way to the French Canadian, and the French Canadian has been largely superseded by the Slav and the Italian. Every one of the older industrial towns has been encrusted in layer upon layer of foreign accretions, until it is difficult to discover the American core. Everywhere are the physiognomy, the chatter, and the aroma of the modern steerage. Lawrence, Massachusetts, is typical of this change. In 1848 it had 5923 inhabitants, of whom 63.3 per cent were Americans, 36 per cent were Irish, and about forty white persons belonged to other nationalities. In 1910 the same city had 85,000 inhabitants, of whom only about 14 per cent were Americans, and the rest foreigners, two-thirds of the old and one-third of the new immigration.

A like transformation has taken place in the manufacturing towns of New York, New Jersey, and Delaware and in the iron and steel towns of Pennsylvania, West Virginia, and the Middle West. For forty years after the establishment of the first iron furnace in Johnstown, Pennsylvania, in 1842, the mills were manned exclusively by Americans, English, Welsh, Irish, and Germans. In 1880 Slavic names began to appear on the pay rolls. Soon thereafter Italians and Syrians were brought into the town, and today sixty per cent of the population is of foreign birth, largely from southeastern Europe. The native Americans and Welsh live in two wards, and clustered around them are settlements of Italians, Slovaks, and Croatians.

The new manufacturing towns which are dependent upon some single industry are almost wholly composed of recent immigrants. Gary, Indiana, built by the United States Steel Corporation, and Whiting, Indiana, established by the Standard Oil Company for its refining industry, are examples of new American towns of exotic populations. At a glass factory built in 1890 in the village of Charleroi, Pennsylvania, over ten thousand Belgians, French, Slavs, and Italians now labor. An example of lightning-like displacement of population is afforded by the steel and iron center at Granite City and Madison, Illinois. The two towns are practically one industrial community, although they have separate municipal organizations. A steel mill was erected in 1892 upon the open prairies, and in it American, Welsh, Irish, English, German, and Polish workmen were employed. In 1900 Slovaks were brought in, and two years later there came large numbers of Magyars, followed by Croatians. In 1905 Bulgarians began to arrive, and within two years over eight thousand had assembled. Armenians, Servians, Greeks, Magyars, every ethnic faction found in the racial welter of southeastern Europe, is represented among the twenty thousand inhabitants that dwell in this new industrial town. In "Hungary Hollow" these race fragments isolate themselves, effectively insulated against the currents of American influence.

The mining communities reveal this relative displacement of races in its most disheartening form. As early as 1820 coal was taken from the anthracite veins of northeastern Pennsylvania, but until 1880 the industry was dominated by Americans and north Europeans. In 1870 out of 108,000 foreign born in this region, 105,000 or over ninety-seven per cent came from England, Wales, Scotland, Ireland, and Germany. In 1880 a change began and continued until in 1910 less than one-third of the 267,000 foreign born were of northern European extraction. In 1870 there were only 306 Slavs and Italians in the entire region; in 1890 there were 43,000; in 1909 there were 89,000; and in 1910 the number increased to 178,000.

Today these immigrants from the south of Europe have virtually displaced the miner from the north. They have rooted out the decencies and comforts of the earlier operatives and have supplanted them with the promiscuity, the filth, and the low economic standards of the medieval peasant. There are no more desolate and distressing places in America than the miserable mining "patches" clinging like lichens to the steep hill sides or secluded in the valleys of Pennsylvania In the bituminous fields conditions are no better. In the town of Windber in western Pennsylvania, for example, some two thousand experienced English and American miners were engaged in opening the veins in 1897. No sooner were the mines in operation than the south European began to drift in. Today he outnumbers and underbids the American and the north European. He lives in isolated sections, reeking with everything that keeps him a "foreigner" in the heart of America. The coal regions of Virginia, West Virginia, Ohio, Indiana, and Illinois and the ore regions of northern Michigan and Minnesota are rapidly passing under the same influence.

Every mining and manufacturing community is thus an ethnic pool, whence little streams of foreigners trickle over the land. These isolated miners and tillers of the soil are more immune to American ideals than are their city dwelling brethren. They are not jostled and shaken by other races; no mental contagion of democracy reaches them.
