moraines stood above the sea. The broad sand plains, so character- 

 istic of broad areas of Long Island, are attributed to the sub- 

 mergence in the ocean as the ice sheet melted. 



The Winooski valley in Vermont, opening at Burlington and 

 heading east of Montpelier, is a replica of the Connecticut valley. 

 It was deeply flooded by the Champlain sea-level water and exhibits 

 well-formed high deltas. The history of its terraces is the same as 

 for the Connecticut. 



It is planned to publish as a bulletin of the State Museum the 

 proofs of the marine submergence of the Hudson-Champlain valley 

 and description of the phenomena. In this connection it will 

 be necessary to make comparison with the corresponding features 

 in New England. 



The study of the surficial geology of the Saratoga quadrangle 

 was completed by Professor Stoller and the final report, with map, 

 submitted. Beginning was also made by him in the study of the 

 glacial geology of the Cohoes quadrangle. 



INDUSTRIAL GEOLOGY 



The collections relating to the economic mineral materials of the 

 State have been so largely augmented during the past season as 

 to constitute practically an entirely new addition to the Museum. 

 The materials have been assembled by solicitation among the repre- 

 sentative industries and in part by personal canvass in the field. 

 Although fairly complete exhibits of the kind have been prepared 

 at different times by the Museum for the expositions at Chicago, St 

 Louis, Portland and Buffalo, there has never been any attempt 

 hitherto to incorporate a series of the products of our mineral in- 

 dustry as a permanent feature of the Museum itself. As a con- 

 sequence, the collections previously made were largely scattered after 

 they had served their purpose of temporary display, and much of 

 the remnant returned to Albany has suffered damage from re- 

 peated removals from one storage place to another. A list of the 

 new collections is included with the Museum accessions for the year. 



It is proper to state that the plan of assembling such an exhibit 

 has met with hearty cooperation on the part of the mining and 

 quarry enterprises concerned, and that many have gone to consid- 

 erable inconvenience and expense in preparing the necessary ma- 

 terials. Acknowledgment may be made in this place for the general 

 support that has thus been received, without which the labor would
