106 JOURNAL OF THE 



duel ion to Lieber^s Fourth Aunual Report, thus giving liis ovvu 

 statement o( the opinions which guided him in the prosecution 

 of the survey. He says:"*" 



The object of a survey of this description appears lo me U> be endowed 

 with various and entirely distinct features. The priniary cause of its institu- 

 tion is unquestionably the development of our natural resources; and this 

 intention of its originators should always continue to retain its prominent 

 position. But yet this commendable object by no means comprises all that 

 should be embraced within the duties of a State Geologist, T think he should 

 not merely endeavor to discover more occurrences of useful minerals and, 

 here and there, labor to repress and prevent expenditure of private means in 

 the search for such gifts of nature, where there is really no promise of suffi- 

 cient importance to warrant it. Attentive as he ought to be to these mc)re 

 practical duties, whether of a [)ositive or negative character, if interested in 

 his own studies, he should not rest satisfied with them alone. His office em- 

 powers him with the means of extending a knowledge of the current progress 

 of his science, and of aiding, often in no inconsiderable degree, in that field 

 of research and exploration of nature, to which he has more particularly 

 devoted his attention. For this purpose he must endeavor to obtain correct 

 information of the latest deveiopn)ents in his department of science, and of 

 the newest results of contemporary explorations of a cognate character. 



Impressed with the conviction that the objects of a geognostic survey should 

 be thus diversified, I have endeavored to explore and define our natural 

 resources, to contribute jis much as j)ossible to the enlargement of knowledge 

 in the particular department of science concerned, and to enable these 

 Reports lo become the vehicles for the distribution of that information on 

 connected subjects, both technological and scientific, which is cradually 

 accumulating elsewhere. * ♦ * * 



The only subject, apart from running notes on petrology, which I have 

 deemed it expedient to enlarge upon more fully, on account of its immediate 

 technological bearings, and the absence of its notice in almost all American 

 and English books on geology, is the study of veins; and in this particular 

 branch, I believe, indeed, that at least the general outlines have been pre- 

 sented in the different Reports. 



The special character assumed hy the survey was the resultant 

 of the foHowiug conditions:

 country" more especially. Mr. Tuomey^s work extended in a 

 general way over the entire State, but a large share of his atten-
