604 THE ICE AGE IN NORTH AMERICA. 



ington county, Pa., a log of wood was also reported to me 

 as found in a situation similar to that described by Professor 

 White, buried thirty feet in the sand of a corresponding 

 high-level terrace some miles back from the present bed of 

 the Monongahela. Wood was also reported to me as found 

 in a similar situation in terraces two hundred and fifty feet 

 above the Alleghany River at Parker, Pa. The terraces 

 there are many miles outside the glacial limit, but by their 

 granite pebbles are unmistakably connected with the Glacial 

 period. The wood was reported as dug from quicksand in 

 a well two miles east of the river, and two hundred and fifty 

 feet above it. 



Another instance of wood which has been preserved in a 

 deposit of the Glacial age is worthy of more minute descrip- 

 tion. In this case I have the advantage of having found it 

 myself. The locality is that of Teazes valley, Putnam county, 

 W. Va. This valley runs from the Kanawha River a little 

 below Charleston to the Ohio at the mouth of the Guyan- 

 dotte near Huntington. The valley, as already described,* is 

 clearly enough a remnant of early erosion, when the water 

 of the upper Kanawha took that course to join the Ohio. 

 The valley is very clearly marked, being about a mile wide, 

 and from two hundred to three hundred feet lower than the 

 hills on either side, and having a remarkably level floor 

 throughout the greater part of its course. The bottom of 

 the valley is filled throughout with a deposit of river-pebbles 

 covered many feet with a mixture of sand and clayey loam. 

 In some places this loam is from thirty to forty feet deep, 

 extending for several miles without interruption, as at Long 

 Level, about the middle of the valley.f Here a section about 

 half a mile long and twenty-five feet deep shows at the top 

 a stiff stratum of clay containing wood at a depth of seven 

 feet. Immediately below is sand containing much iron, and 

 cemented together by the infiltrations of the ore. The stra- 

 tum above, containing the wood, had never been disturbed,
