confined to local experience. Except on Long Island in connection 

 with the work of the United States Geological Survey and the New 

 York City Board of Water Supply, no systematic boring for the 

 determination of underground water has been carried on. These 

 investigations are of great importance and will soon become of 

 imperative necessity. It is now impossible to advise with local 

 communities seeking artesian water or abundant supplies of 

 pumped water, but the exactions of the State and local boards of 

 health and the demands of the communities will soon require this 

 information from the State. This line of investigation has not yet 

 been taken up by the water supply division of the Conservation 

 Commission, and probably could not be intelligently handled except 

 by a corps of experienced geologists. 



The study of surface water supplies of this State was inaugurated 

 in this office and the first report thereupon, " The Hydrology of 

 New York," published as one of its bulletins. The proposed line 

 of investigation of the subsurface supplies of water might with 

 equal propriety be inaugurated here.

Exhibit at the Panama-Pacific Exposition. In further refer- 

 ence to this exhibit it may be stated that the materials included a 

 comprehensive array of the products of mine and quarry, as well as 

 illustrative matter in the forms of models, charts and maps, and 

 was grouped in an area of about 3500 square feet under the central 

 dome of the building, most accessible to visitors. The exhibit was 

 surrounded by others from states and countries more especially 

 noted for their mineral endowments, but none the less attracted 

 much attention. The variety of products was one of its features 

 that caused much comment. In the distribution of awards it 

 received favorable consideration ; the grand prize was given for 

 the display as a whole, and numerous medals — gold, silver and 

 bronze — were allotted among the individual . exhibits. 



Much of the material will be returned to Albany and used to 

 supplement the State Museum collections. In the list of exhibits 

 to be thus disposed of is the large model of the Silver Springs 

 works of the Worcester Salt Co. This was built recently with a 

 view to its display at the exposition where it was the center of much 

 interest, and no doubt it will be an attractive feature of the 

 economic section of the Museum, in which now, through the 

 generosity of the exhibitor, it will find a permanent place. A
