make an areal, economic and structiu-al sur- 

 vey of the crystalline rocks of the Delaware 

 Water Gap, Easton and AUentown quad- 

 rangles, in New Jersey and Pennsylvania. 



A thorough field revision of the areal and 

 economic geology of the Franklin Furnace 

 quadrangle, 'New Jersey, will be made by Dr. 

 A. C. Spencer, who will also prepare a report 

 on the economic geology of the district. Dr. 

 Spencer will cooperate with Professor J. E. 

 Wolff in the preparation of the Franklin 

 Furnace folio. 



New York. — ^Professor E. S. Tarr will com- 

 plete his investigation of the Pleistocene geol- 

 ogy of the Watkins Glen quadrangle, ISTew 

 York, and will prepare the Pleistocene section 

 for the Watkins Glen folio. He will also in- 

 vestigate the Pleistocene geology of the Har- 

 ford-Owego quadrangle, New York, and pre- 

 pare the Harford-Owego folio in cooperation 

 with Professor H. S. Williams. 



Professor Williams, assisted by Dr. E. M. 

 Kindle, will make an areal and economic sur- 

 vey of the quadrangle that embraces the Dry- 

 den, Harford, Owego and Appalachian quad- 

 rangles. New York. 



Professor J. F. Kemp will continue the 

 areal and economic survey of the eastern part 

 of the Adirondack region. 



Nevada. — Mr. J. E. Spurr will visit the 

 Tonopah district, Nevada, some time during 

 the summer, in order to make a final revision 

 of his conclusions before publishing the report 

 on the Tonopah ore deposits on which he has 

 been at work for the last year. 



North Carolina, South Carolina, Tennessee 

 and Georgia. — Mr. Arthur Keith will com- 

 plete areal and economic surveys of the Mount 

 Mitchell, Nantahala, Cowee, Pisgah, Roan 

 Mountain and Morganton quadrangles, in 

 North Carolina, South Carolina and Tennes- 

 see, with a view to the preparation of geologic 

 folios. Assisted by Mr. Hoyt S. Gale, he will 

 make a reconnaissance of the Hickory, Pick- 

 ens, Walhalla and Dahlonega quadrangles. 

 North Carolina and Georgia. Dr. W. Lind- 

 gren, assisted by Mr. L. C. Graton, will make 

 a preliminary investigation of the mineral 

 resources, particularly gold and tin, in several 



counties of the northeastern part of South 

 Carolina. 



Ohio and West Virginia. — A revision of the 

 Cadiz-Steubenville quadrangles in Ohio and 

 West Virginia will be made by Mr. M. E. 

 Campbell, who will prepare the Cadiz-Steu- 

 benville folio in cooperation with Mr. W. T. 

 Griswold. 



Pennsylvania. — Mr. M. E. Campbell will re- 

 vise the mapping of the Slatington quadrangle, 

 Pennsylvania, for the preparation of the 

 Slatington folio. In cooperation with the 

 state of Pennsylvania, he will also survey for 

 folio publication the Amity, Eogersville, Bur- 

 gettstown and Claysville, quadrangles. In this 

 work he will have the assistance of Messrs. 

 W. T. Griswold and F. C. Clapp. 



The Trenton limestones of eastern Pennsyl- 

 vania and their continuation into New Jersey 

 will be mapped by Mr. E. S. Bassler for the 

 purpose of furnishing information to Mr. E. 

 C. Eckel that may be of assistance to him in 

 the preparation of his report on the cement 

 resources of the United States. 



In cooperation with Messrs. N. H. Darton 

 and W. B. Clark, Dr. Florence Bascom will 

 complete the field work and prepare for publi- 

 cation the Philadelphia special folio. 



Texas. — Mr. E. C. Eckel will visit north- 

 eastern Texas, particularly Marion, Cass, 

 Morris, Camp, Harrison and Upshur counties, 

 for the purpose of making a reconnaissance 

 examination of iron-ore deposits and deter- 

 mining the areas in which topographic and 

 geologic work can most advantageously be 

 taken up next year. 



Utah. — Mr. J. M. Boutwell will complete an 

 investigation of the mining geology of the 

 Park City district, Utah. He will also make 

 a reconnaissance of the areal, stratigraphic 

 and structural geology of the western portion 

 of the Uinta Mountains. Mr. Lester H. Wool- 

 sey will assist him. 



Vermont. — Areal and economic surveys will 

 be made in western Vermont by Professor T. 

 Nelson Dale. 



West Virginia. — Dr. George H. Ashley, as- 

 sisted by Mr. W. C. Phalen, will make areal 

 and economic surveys of the Nicolas quad-
