CLEVELAND MORAINE. 643 



noted, but they do not present features much different from those ah-eady 

 mentioned. Commonly, they show horizontal bedding, though it is often 

 slightly wavy. Near the border of a knoll the well-defined beds usually 

 give place to poorly assorted material with ill-defined bedding planes. 



The well sections have thrown considerable light upon the depth and 

 structure of the drift both on the uplands and in the valleys. A few of 

 these will be next considei'ed. 



On the portion of the moraine lying west of the Cuyahoga the wells 

 usually penetrate a typical till, such as appears in plains to the west. They 

 have in some cases reached rock at 20 to 25 feet, but in other cases have 

 penetrated to a much greater depth without reaching the bottom of the 

 drift, the supply of water being from thin beds of sand associated with 

 the till. 



At Randall, east of the Cuyahoga, a well 96 feet deep, on Chris. 

 Emery's farm, struck stone at bottom thought to be bed rock. It was 

 through ordinary blue till nearly the whole depth. A prospect boring for 

 coal was attempted near Randall some years ago by Otis Forer, which 

 penetrated fully 100 feet of drift. 



Gas borings in the Chagrin Valley, near Gates Mills, Orange, and 

 Wilsons Mills, pass through from 120 to over 200 feet of drift. The lower 

 portion of the drift is a fine silt or blue clay, but the upper portion is 

 rather stony. 



In the valley of East Chagrin River, near the Chardon and Cleveland 

 road, a farmhouse well penetrated 161 feet of drift. For 100 feet the drift 

 is mainly till, below which it is a fine sand. 



At Wallace Weaver's, 2 miles west of Chardon, there is a flowing well 

 which obtains its water from the sandstone, but it penetrated 30 feet of 

 drift before entering rock. 



In Hampden Center the drift is mainl}' till, and several wells strike 

 rock as follows: William Cutt's, at 35 feet; E. Thayer's, at 36 feet; 0. R. 

 Chamberlin's, at 35 feet; post-office well, at about 60 feet. 



In Grand River Basin the wells usually penetrate a large amount of 

 blue clay which is reported to carry but few pebbles. Much of it may be 

 water-laid silt, deposited in a lake outside the ice sheet, iDut tlie surface 

 portion as deep down as the base of the moraine seems to be ordinary till. 

 The wells, as shown in the table below, have in some cases penetrated
