STATE GEOLOGIST. 39 



ery possible way Every specimen or item of information will 

 be thankfully received. Proprietors and managers of important 

 enterprises, have, in some instances, greatly mistaken their true 

 interests, in failing- to furnish the data sought for, even by re- 

 peated applications. No authority is considered more reliable 

 than a State Geological Report, on the value and extent of the 

 mineral resources of a particular locality or district; and the 

 interests of proprietors of mineral locations, require them to 

 see that every evidence of the value and productiveness of their 

 locations is placed in the possession of tlje State Geologist. 

 Moreover, isolated facts or specimens calculated to throw 

 light upon the occurrence of any rock or mineral, in any part 

 of the State, especially those parts not yet explored, will always 

 prove of interest, and, in some cases, may constitute critical 

 data for deciding questions in doubt. 



It will be seen, therefore, that two general classes of infor- 

 mation are desired. 



1. Facts calculated to contribute to our knowledge of the 

 characters and distribution of our rocks, with their included 

 minerals. 



2. Statistics showing the condition of all mining enterprise* 

 and their productiveness. This class of information embrace8 

 every species ef manufacture from the mineral substances of 

 our dtate, as bricks, tiles, pottery, earthenware, pipes, fire- 

 bricks, concrete, moulding sand, glass, fluxes, land plaster, 

 calcined plaster, alabaster ornaments, salt, its impurities, mar- 

 ble, quarry stones, quick-lime, water-lime, grindstones, hones, 

 coal, precious stones, iron, copper, lead and other metals. 



When the geological department is made the common depos- 

 itory of all such information, the way will be opened to such a 

 presentation to the world of our multifarious sources of wealth 

 as will constitute the strongest possible attraction for settle- 

 ment, enterprise and capital.
