back of this report for the map, and on account of active work in progress in the lower part of the state which it was desirable to incorporate therein, led us to issue in 1892, as Bulletin No. 2, an account of these marls in separate form.

In 1893 appeared Mr. Gibson's report on the Geology and Resources of Murphree's Valley, the publication of which had been delayed on account of the lack of a suitable map for its illustration. His report on the Coal Measures of Blount Mountain has just been published, 1894, and he is at work upon a preliminary report on the Coosa Coal Field.

Dr. Wm. B. Phillips, in 1891, undertook the examination of the gold region, spent part of one summer in the field work, and prepared a partial report thereon, but was unable to complete this work, and it was taken up in 1893 by myself and Mr. W. M. Brewer. It has been conclusively shown that these fields, with suitable methods of extracting the gold, can be worked in many places at a profit. The great activity now prevailing there leads us to think that the mining of gold will soon take an important place among the industries of the state.

Coöperation of the U. S. Geological Survey.Soon after the consolidation of the United States Geological Surveys into one organization in 1879, propositions were made by the director for coöperation with the state surveys, in accordance with which it was agreed that the U. S. Survey should make in Alabama accurately measured sections of our Paleozoic formations at two points selected after full consultation. This plan was afterwards slightly modified, and the results were published in 1892 as Bulletin No. 4 of the State Survey, a Report on the Geology of Northeastern Alabama and the adjacent parts of Georgia, by C. W. Hayes. This region in Alabama had already been pretty closely examined by the state survey, so that the change in the original plan caused some degree of duplication of work, but the mode of treatment of the subject and the map showing the connection with Georgia make this an exceedingly acceptable contribution.

Another result of this coöperation was a trip in 1883 down
