field of work. Numerous analyses of marls, peats, and commercial 

 fertilizers were made, and directions looking to the extension and 

 use of these were widely disseminated. Many analyses of soils were 

 made, and the people of the State were informed as to the methods 

 of soil improvement. 



From 1872 to 1877 the survey doubtless saved to the people of the 

 eastern and middle regions of the State many thousands of dollars 

 through its inspection of the commercial fertilizers sold and used in 

 these regions; and in 1877 the State geologist was largely instru- 

 mental in the establishment and organization of the " department of 

 agriculture, immigration, etc.," and the agricultural experiment sta- 

 tion, which since that time has been of great value to the people of 

 the State in regulating the manufacture and sale of commercial fer- 

 tilizers, and in other ways. 



Again, the survey has been of benefit to the people by advertising 

 the 7iatural resources of the State in this and in other countries. 

 This has been done by making exhibits of specimens of minerals, 

 ores, woods, etc., illustrative of the resources of the State, and 

 through the published reports of the survey and official correspond- 

 ence of the geologist with persons in our own and other countries. 

 Such exhibits as referred to were made by the survey at the Vienna 

 exhibition (1874), Philadelphia (1876), and Atlanta (1881). 



The survey inaugurated the movement of a few years later looking 

 to the increase in supply of food fishes in the streams of the State; 

 and (as mentioned already) established and kept in existence for a 

 time a series of meteorological stations in different portions of the 

 State. It revived the silk-raising movement in North Carolina — a 

 result of the visit of the geologist to the Vienna exposition. It 

 measured the water power of all the important rivers of the State. 

 It has left the public a fairly good knowledge of the physical fea- 

 tures and climatology of North Carolina. 



The educational feature should be kept in mind even when con- 

 sidering the material benefits resulting from the work of the survey. 

 Through occasional public lectures by the State geologist at places 

 in different portions of the State, through published reports, arti- 

 cles in newspapers, and private correspondence, the people of the 

 different sections were informed, as far as was practica^ble under the 

 circumstances, concerning the natural resources of their respective 

 regions. Such inform.ation is of material benefit in that, on the one 

 hand, it encourages investments in cases where there is reasonable 

 ground for expecting success; and, on the other hand, where there 

 is no such ground, the attention of persons interested is turned to 

 some other undertaking, and loss of both time and capital is pre 

 ^T-nted.
