and destroying the flow of artesian wells. The water in these shallow 

 wells sometimes rises nearly or quite to the surface, but the most of the 

 artesian wells rise from a gravel bed that lies on the rock. They have 

 a depth of 30 to 35 feet. This water-bearing stratum may also be the 

 real source of the artesian flow of some of the shallow wells, since the 

 first bed of sand containing water is known to not infrequently be con- 

 nected with it so closely as to destroy the flow of the deeper wells. The 

 general slope of the surface here is to the south-east. The hard-pan 

 Drift-sheet is the confining stratum. The water finds access to the deep- 

 seated gravel bed by passing through connected beds of water-bearing 

 gravel and sand, in some region at a higher level, tpward the north-west. 

 The rock in Carryall township is generally 35 to 40 feet below the sur- 

 face, yet it was positively asserted by Mr. McCormick that two wells 

 about on the section line between 4 and 9 went down 70 to 80 feet with- 

 out striking the rock. A deposit of yellow lake sand was met at Paul- 

 ding Center, on Joseph Morrow's land. It does not rise much above the 

 surface. There is considerable sand of the same kind on the land of 

 L. Baldwin, north of Emerald, near the Maumee, and in Emerald town- 

 ship, between Six Mile Creek and the canal. Glacial marks were observed 

 on the Corniferous, section 30, Auglaize, S., 40° W., and on section 31, 

 Auglaize, S., 48° W. ; on the Onondaga at Charloe, S., 35° W. 



The following list of statistics, obtained in reference to wells in Paul- 

 ding county, will be of importance in this connection :
