GEOLOGICAL SURVEYS IN ALABAMA. 283 



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 Moun- 

 tain has just been published, 1894, and he is at work upon a pre- 

 liminary 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. 



Cooperation of the U. S. Geological Survey. Soon after the con- 

 solidation of the United States Geological Surveys into one organ- 

 ization in 1879, propositions were made by the director for coop- 

 eration 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 ori the Geology of Northeast- 

 ern 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 cooperation was a trip in 1883 down
