afford quick and frequent service to several growing cities. 

 Neither of these electric lines follows the shore ridges, although 

 they are within convenient distance, one north and the other 

 south. The numerous muck areas, noted especially along the 

 Maumee and Whittlesey shorelines, are adapted to market 

 gardening.

To some extent these former water bodies have been factors 

 in making the Berea sandstone more accessible. The principal 

 quarry areas now being worked are (1) near Bsrlin Heights, and 

 (2) southeast of Brownhelm; the latter is generally known as the 

 ''Amherst" quarry. Near Berlin Heights the quarry is located 

 in a cliff of the Whittlesey level ; this is the older of the two quar- 

 ries, but the stone does not appear to be as satisfactory as that 

 from the Amherst area. The first Berea sandstone quarry in 

 this part of the state was opened south of Brownhelm station; a 

 crack from the Lake Shore and Michigan Southern Railway 

 afforded good shipping facilities ; later, stone of better quality was 

 found elsewhere and this quarry was abandoned. Perhaps the 

 most extensive quarries now being worked in the Berea sand- 

 stone are those at Amherst ; at no other place in Ohio has such a 

 thickness of the Berea been operated. The structural conditions 

 of this rock horizon are here best suited for quarrying. 



The abundant gravel and sand of these shorelines will lead to 

 an increasing local use of cement in making building and other 

 structural blocks, as lumber becomes higher in price. Already 

 one notes the beginning of this use. 



The north-south highways, within easy reach of the old beaches, 

 for decades have been coated with the gravel from the shore 

 ridges. At two points, one near Berlin Heights, the other near 

 Ogontz, railroads have removed many acres of beach gravel for 

 ballast.
