Report of the Director. 11 



soutliern counties are of the age of the Chemung,'^ but, from the great 

 difference in character of the fossils in different localities, it may not 

 be regarded as proven that these beds are all of the same horizon. 

 Thus far, we liave failed to trace the extension of these conglomerate 

 beds to the eastward of Alleghany county.f From some of these 

 localities, I have made large collections during the past year, and 

 Mr. Yandeloo, under my direction, has made still more extensive 

 collections from the same, and from other localities in the southern 

 counties of the State. 



These investigations, in the entire southern part of the State, show 

 the great need of a revision of the Geological Map of the State : 

 indeed, it has long been known that the limits of formations, as laid 

 down on that map, are, in many instances, quite erroneous, and I am 

 sure we could render no more acceptable service to the science, or do 

 anything better adapted to meet the wants of our intelligent teachers 

 and students, than the preparation of a new and more accurate geo- 

 logical map of the State. The work already accomplished is but a 

 beginning, and I would very earnestly recommend that authority be 

 given me to continue these investigations as far as practicable with 

 the means at our command, with a view to the completion of such a 

 map as I have suggested, and one which, when published in a proper 

 form, might find its way into every school, academy and college 

 within the State, and become the source of valuable, practical 

 knowledge. 



General Work of the Museum. 



Heretofore the collections in each of the departments have been 

 indicated only by the label of generic and specific names among 

 the natural history objects, and by the simple names among rocks 

 and minerals. In order to give more general information, and at the 

 same time a view of the classification of the objects in the museum, 

 another series of labels has been added. These are large paper 

 labels, covered with glass to prevent the rapid soiling of exposed 

 paper surfaces. The geological wall-labels have been arranged over 

 the wall cases of the first floor, indicating the geological systems and 



* The relations of some of the outlying conglomerates south of Olean in New York, and the adja- 

 cent parts of Pennsylvania in McKean county, to the Chemung group and Coal measures, have not 

 yet been satisfactorily determined. 



tSome thin interrupted layers of conglomerate are knov?n in the more eastern counties, but it 

 cannot be demonstrated that these beds hold Ihe same relative position as those of Alleghany, Catta- 

 raugus and Chautauqua counties.
