be considered as more than an approximate representation of 

 the areas of geological formations in the State. An accurate 

 geological map of the State is still a desideratum. 



In this connection I beg to make a few suggestions for some 

 of the most important work that the State ought to undertake 

 as a continuation of its Geological Survey. In part these sug- 

 gestions are the same as those I had the honor to make in 

 my report to your Excellency and the Board of Trustees 

 of the State Museum, in January, 1889. They were also used 

 as the substance of two bills introduced in the last Assembly of 

 the State Legislature, but, although seemingly meeting the apt 

 proval of the Legislature, were "tabled" at the third reading. 

 I would suggest: 



1. That a continued collection be made of logs of all borings, 

 shafts, etc., in the State. Owing to the imperfect character of 

 the records of such undertakings, as usually made, each locality 

 where a boring or sinking of a shaft is in progress should be 

 visited, or, at least, arrangements should be made with those 

 in charge of the work, for the proper preservation and identi- 

 fication of samples of the strata. 



2. That a detailed topographic, or at least hypsometric survey 

 of the State be made on a plan conforming to similar surveys 

 already made, either wholly or in part, by New Jersey, New 

 York, Massachusetts, Wisconsin and Michigan, and now in pro- 

 gress in Pennsylvania and Minnesota. 



Thus would be furnished the necessary data for elucidat- 

 ing many problems of the greatest economical import- 

 ance to such industrial pursuits as require a correct insight into 

 the geological structure of the State. I would therefore suggest:
