or five weeks, and tlie expense attending it was in excess of the 

 estimate, so that, when excavation became possible, our means 

 did not enable us to carry this to completion. The area of 

 about one third of the pond bottom was carefully dug over, and 

 additional evidences of the mastodon skeleton were found; but, 

 as we had reached the limit of our appropriation and were in 

 danger of passing beyond it and incurring an expense which 

 could not well be borne, and as I was unable to obtain additional 

 assistance from any private source, it became necessary for us 

 to end the work with the excavations incomplete. Hunting 

 mastodon skeletons carries with it a large element of uncer- 

 tainty, as such skeletons are very rarely complete. The fluidity 

 of the soil in which they have become mired disjoints and scat- 

 ters the bones, with the result that the finding of one part or 

 a considerable portion of a skeleton does not guarantee the 

 presence of all the bones. The parts we have obtained have 

 features of considerable interest, specially the lower incisors 

 to which reference has been made, and the possibility of re- 

 claiming the remainder of the bones is still about as good as 

 it was at the beginning of the enterprise. 



Cooperative work with the U. S. geological survey on the Sala- 

 manca quadrangle. In the season of 1900 the work which had 

 been undertaken on the areal geology of the Olean topographic 

 sheet was brought to completion, and the results carefully 

 worked out both here and by the representative of the U. S. geo- 

 logical survey, Prof. L. C. Glenn. This work and report thereon 

 will be published during the coming year. With the opening of 

 the present season the work was continued to the adjoining 

 quadrangle on the west (Salamanca), in which Prof. Glenn was 

 associated with Myron L. Fuller of the IT. S. geological survey. 

 Charles Butts, who had during the previous season been the 

 representative of this department in that work and who had 

 prosecuted the stratigraphic and paleontologic determinations 

 in the office during the winter, had in the meantime received 

 an appointment as assistant geologist on the U. S. geological 

 survey, but by the concession of M. R. Campbell, geologist in
