Excerpt from Preliminary Report on the Copper-Bearing Rocks of Douglas County, Wisconsin The method followed in the season's field work was to visit all parts of the two areas above mentioned which were known to have rock outcrops, or in which outcrops might be reasonably expected. In. Such parts north and south traverses were made at intervals of one-half mile, or more frequently when occasion demanded. Thus, in the region where outcrops occur fre quently, the north and south section lines, the north and south quarter section lines and some of the east and west section lines were followed. The larger streams, and in fact all the streams which might be expected to cut down to the bed rock, were also followed. The outcrops seen were located carefully by pacing, and the position of each was indicated as so many paces north and so many paces west of the southeast corner of the given section. In this manner of locating paces equals one mile. Rock samples were taken from most of these outcrops. In all about 775 rock numbers and a considerably greater num ber of specimens were collected.

Thus this report is necessarily of the nature of a preliminary rather than. Of a final report. At the same timeit should be stated that the essential facts concern mg the geological structure of the areas examined, the geograph.
