charge of the work throughout this region and northern Penn- 

 sylvania, Mr Butts has been allowed to represent us in the ac- 

 quisition of material necessary for paleontologic determinations 

 from localities in the Salamanca area. 



The work in the field as originally planned when the appro- 

 priation was made has now been brought to completion, and 

 there remains but the summarization of the results acquired 

 and the detailed representation of the stratigraphy on the topo- 

 graphic sheets. This will be the work during the coming winter 

 of Prof. L. C. Glenn, and the completed map will be communi-

 work on the Olean sheet.

 Prof. James Hall, have now been brought to a conclusion and
