 comes to the water level at a brook of some size, 

 where the overlying sandstone contains lenticular

 behind a narrow point, there is another brook, at 

 which again the dark shale is at water-level, but a 

 short distance further it is reiplaced by pebbly 

 sandstone, the whole cliff probably two hundred 

 feet in height, being composed of pebbly sandstone
