gn 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 t
