in the county, and a salt manufacturing company is established 

 in Susquehanna county, at a salt spring on the dividing line 

 with Bradford county. No rock salt has been found, neither 

 have any wells been yet dug in this last county for brine. At 

 Rome, eight miles north-east of Towanda, is a fine mineral 

 spring, impregnated with sulphur, iron, &c. Inflammable gas 

 rises in large bubbles from the bottom. The medicinal proper- 

 ties of this spring have been found very efficacious in cutaneous 

 diseases. No natural caves have as yet been discovered in this 

 county, nor any osteological remains, except an elephant's tooth. 

 An exploring expedition, for the purpose of making geological 

 examinations of the most interesting parts of the county of Brad- 

 ford, is now preparing ; it is intended to communicate the re- 

 sults to the Geological Society of Pennsylvania. 



A communication on the geology of Wayne county, Pennsylva- 

 nia, accompanied with a map and section, from Jacob P. Davis, 

 Esq. and dated Bethany, Pennsylvania, was read. The follow- 

 ing is an extract from it : — 



" The principal features of the county of Wayne are, a contin- 

 uous upland, occupying by far the largest portion of surface, the 

 long narrow valleys by which this upland is indented, and a few 

 incidental eminences to which the distinction of mountains is ap- 

 plied. The general average elevation of the upland is estimated 

 at about thirteen hundred feet above tide water. 



" Moosic mountain, near the western line of the country, rises 

 above the upland about six hundred feet ; having a total eleva- 

 tion at Rix's Gap, on the route of the Rail road, of nineteen hun- 

 dred and ten feet above tide water. The term " gap," as ap- 

 plied to the passes of this mountain, does not signify a cleft or 

 opening ; the top of the mountain being continuous : it merely 

 signifies a convenient slope. Beyond the northern extremity of 

 the Moosic rises Mount Arrarat, which is about the same height 

 as the Moosic. Besides these there are a few eminences of but 

 minor note. 



" The upland, with its appurtenant valleys, appears to afford 

 the most interesting variety, the features of which are particu- 

 larly defined by the course of the waters. All the larger 

 streams have their sources at or near the summit of the upland, 

 increasing in their passage by the confluent springs and rivulets ;
