TABLE 2.-Increase in the average number of employees in glass manufacturing in the United States, 1870-1905, and in the principal glass-manufacturing States, 1880-1905. [Compiled from United States Census, Special Report on Manufactures, Part III, 1905, Table 2, pp. 840-841.]

For the purpose of determining the racial composition of the operating forces of the industry and to ascertain how far the growth of the industry had been dependent upon or affected by recent immigration, a study was made of the glassworkers and the members of their households in the States where the industry had been established and where it had had its greatest development during recent years, or in other words, in the States of Missouri, Illinois, Indiana, Ohio, Pennsylvania, West Virginia, New York, and New Jersey. The map submitted shows the geographical scope of the investigation and the location of the establishments of which the employees and the members of their households were studied in detail.

A total of 660 households, the heads of which were engaged in various forms of glass manufacturing, were studied in detail. These households were selected so as to represent the different divisions of the industry, and geographically distributed so as to be representative of conditions prevailing in the different glass-manufacturing areas, The following table shows the households studied, according to general nativity and race of head of household.

The above table shows that of the 660 households studied in this industry, 80.5 per cent are households the heads of which are foreignborn, 2.1 per cent are households the heads of which are native-born of foreign father, and 17.4 per cent are households the heads of which are native-born of native father. Among those whose heads are foreign-born a slightly larger number of Slovak than of Polish house holds were studied-the number of these households combined con stituting 45.8 per cent of the total number of households studied After the Polish households, it will be seen that the number of Germa households constitute a considerably larger proportion of the tota number of households studied than do the Flemish, and a very muc larger proportion than do the North Italian, Magyar, South Italia or French households, in the order named.
