238 rts of the Warrior Field together with an attempt at correhiting 

 the same. The report contained also many details of the occur- 

 rence and composition of iron ores and limestones of this district. 

 The report for 1876 continued the examination of the valley re- 

 gions, and contained a paper on the Alabama fresh water shells 

 by Dr. James Lewis, contributed by Mr, Aldrich. 



In 1877-78 attention was turned to the Warrior coal field, till 

 then comparatively unknown, and maps were published of Walker. 

 Fayette, Marion, and Winston counties, vvhich Avere practically un- 

 derlaid with coal measures. Notv\"ithstanding the fact that no coal 

 was mined at tliat time in all this region, and it was not possible with 

 the means at the disposal of the sur\H^y to open the seams so as to 

 show their true value, the publication, especially of the maps, turned 

 the attention of investors to these counties, and the next few years 

 witnessed great developments. 



In 1878-79 a movement was set on foot to secure an appropri- 

 ation from Congress for the purpose of making navigable the Up- 

 per Warrior Elver to develop the coal seams along its course, and 

 Doctor Smith, with Henry McCalley and Josepli Squire, ran a line 

 of levels from the forks of the Warrior down to Tuscaloosa, and made 

 special reexamination of the coal seams within available distances 

 from the river. The expense of this surve}' was borne chiefly by the 

 War Department, but the map and report were published by the sur- 

 \ey. In tliis document the details of the coal seams were given with 

 a much greater degree of fullness than heretofore, togethei* with numy 

 facts bearing upon their stratigraphical relations. There was also 

 given by Mr. McCalley a continuation of the description of the Ten- 

 nessee Valley, begun tlie year before, togetlier with the analyses of 

 some 50 coals from the Warrior field. 



Ex-penses.- — The cost of printing the repoits of the survey was 

 paid out of the general printing fund of the State. This amounted 

 to $6,760, which, added to the $8,000 appropriated, gives a total of 

 $14,750 for the 10 years' work, or an average of $1,475 a year. 



As w^ill be noted, the survey had no official connection willi any 

 other organization, though in 1880 Doctor Smith prepared for the 

 Tenth Census a report on cotton culture in Alabama and Florida, 

 the results of which, so far as Alabama was concerned, were published 

 in the survey report for 1881-82. In addition to the special descrip- 

 tive matter, this report contained a general discussion of the com- 

 position, mode of formation, and properties of the soil, and the 

 changes produced by cultivation. The maps were prepared for the 

 census work, but the survey was given the privilege of using the 

 plates. The other illustrations were prepared by the survey.
