PROSSER — THE GENESEE SECTION. 



7' 



Although the first stratum of rock salt is about 2400' in depth, 

 some 600' deeper than m the \Varsaw wells, still it has been worked 

 and Mr. Bush informs me that several thousand barrels of salt have 

 been manufactured. 



At Silver Springs, two miles northwest of Castile, are the salt 

 works of the Duncan Salt Co., who have drilled five wells at this 

 place.

(1.) Fifih ann. Rept. State Geologist [of New York] for 1S85, p. 25. Dr. Engelhardt mentions three 

 wells at this place, and states that there are " two salt veins of twenty and sixty feet thickness in each, 

 separated by thirty-five to forty feet shale" (Ann. Rept. Supt. Onondaga Salt Springs, for 1888, p. 

 19). But on Chart II Engelhardt copies Professor Bishop's section without change and the data on 

 Chart III also agree with Bishop. 



(2.) October 29th, 1891, Mr. J. W. Duncan, President of the Duncan Salt Co., wrote me that the 

 above well was about 1500' south of the N. V., L. E. & W. R. R. station at Silver Springs and about 

 15' below the level of the railroad.
