 Soft Alaple and Swamp Ash with an undergrowth of Willow 

 and Poison Sumac. The drove well at Air. Brown's harn shows 

 seventeen feet of ]jeat, three feet of yellow' clay, then hard pan

 water. Impatiens stems were found in the muck at a dei)th of 

 three feet. 



The till plain hordering Buckeye Lake on the west has an 

 elevation of 890 feet close to the lake, wliile the lake surface 

 is 892 feet above sea level. 



The eastern portion of Buckeye Lake is surrounded by 

 moraines in which large boulders are cjuite frequent. The land 

 has a distinctly hill and valley topography, however, the highest 

 elevation within 5 miles of the lake is I,I00 feet, no higher than 

 the crest of the water shed to the west; but the surface is more 

 deeply dissectefl and the drift cover is thinner, hence the greater 

 prominence and ruggedness of tlie hills. 



Just east of the southeastern extremity of the lake, the rim 

 of hills is dissected by a valley a mile and one-half wide. Just 

 east of Thornville Station a morainal loop crosses the valley 

 and completely blocks it except for a narrow cut, which is now- 

 occupied by the parallel tracks of the Shawnee branch of the 

 Zanesvillc aufl Western railroad from the south, and the Balti- 

 more and Ohio from the north. The cut wdiose present surface 

 is 900 feet above sea level, is partially filled with overflow clays 

 and gravel. 



Jonathan Creek has its source in the hills immediately south 

 of the cut and here the present valley of Jonathan Creek is two 

 miles wide. The cut above mentioned is very evidcnti}- an over- 

 flow channel for the lake. The latter from its shape, position 

 with reference to the valley of Jonathan Creek and the morainal 

 loop must be regarded as a finger lake, formed in the ui)per por- 

 tion of the old valley of Jonathan Creek by the morainal loop 

 at Thornville Station.-' The waters of the lake cut thru the 

 moraine at Thornville Station,'"' then later found a lower out-
