dons detaclied cliff cut off by the action of the sea from the 

 mainland, satisfactorily represents that portion of the limestone 

 series to which in northern Gaspe the term Grande Grcve lime- 

 stones has been applied. This mass of reddish and yellowish 

 limestones rising- from the sea with sheer walls and vertical 

 strata is profuse in interesting fossils, of which a large number 

 were obtained, together with interesting series from the lime- 

 stone exposures of earlier age. It is safe to say that the col- 

 lections in the possession of the State Museum, both of the fossils 

 at Perce and of those at Grande Greve, are without equal. In a 

 subsequent part of this report I have added a brief preliminary 

 account of the stratigraphy and paleontology of Perce. 



Areal survey of the Elmira, Watkins, Ithaca and Waverly quad- 

 rangles. As reported last year operations were carried on during 

 the season of 1902 in cooperation with the United States Geo- 

 logical Survey in an areal survey of the Elmira quadrangle. 

 Under this arrangement as carried into practice in the Olean 

 and Salamanca quadrangles stratigraphers were furnished for the 

 field work from the corps of the survey and their expenses were 

 met from the appropriations of this department, and we under- 

 took at the same time to acquire the necessary paleontologic 

 collections for proving the stratigraphic work. The strati- 

 graphic work on the Olean and Salamanca sheets was chiefly 

 done by Prof. L. C. Glenn, a skilful and exact observer, and the 

 paleontologic collections therein were acquired and largely de- 

 termined by Mr Charles Butts, representing this department. 

 In my judgment the work of these two men was carefully exe- 

 cuted, though leading to some divergence of conclusion with 

 regard to classification. 



The basis of this cooperation conceded to us the use for our 

 publications of such maps and reports as the geologists of the 

 United States Geological Survey should prepare, but we have 

 found it impracticable to avail ourselves of this provision, first, 

 for the reason that the scale of the United States Geological 

 Survey folio maps is one we regard unsuited to our practice and, 

 again, that the execution of these maps and reports was to
