PART 1.-GENERAL SURVEY OF THE COPPER MINING AND SMELTING

INDUSTRY.

CHAPTER I.

INTRODUCTION.

Explanation of study—The territory studied Households studied-Members of

households for whom detailed information was secured—Employees for whom information was secured — The preparation of the report—[Text Tables 1 to 6 and General Tables 1 to 3).

EXPLANATION OF STUDY.

The following report is based primarily upon information received for copper-mine workers and may be accepted as representative of conditions in the territory investigated. In its tabulations, however, a small proportion of employees of smelters appear, due to the difficulty of eliminating the information received for these persons because of the close relations existing between the operations of mines and smelters in the copper ore bearing districts. The employees of smelters include only a part of the employees in those smelters located within the copper ore producing territory studied.

THE TERRITORY STUDIED,

In the course of the investigation detailed information was secured for employees of mines and smelters in the copper-mining district of the northern peninsula of Michigan, and from those of the coppermining territory of southeastern Tennessee. Households, the heads of which were employed in the copper mines and smelters, were studied exclusively in the Michigan district.

HOUSEHOLDS STUDIED.

A total of 504 households, the heads of which were employed in copper mines or smelters, were studied. In the table next submitted the number and percentage of households of each race and nativity group is shown.
