Returning to the Cheshire side of the river Tame the drift covers 

 the edges of the middle series, the dip of which is west at an angle 

 varying from 18° to 42°, and along the line of Chapel Hill, where it 

 covers the lower seams of the middle series. The following is a section at 

 Victoria Colliery : —

The boulders distributed over this area, extending from the river 

 Tame at Dukinfield Hall to Lyne Edge, varying in size from a few 

 hundredweight to three tons, are found mostly resting upon the marl at 

 the base of the gravel beds, and consist of felsites, hornblendic granites, 

 andesite, and andesitic ash, some raicro-granites and Eskdale granites. 

 They are mostly rounded, sub-angular, and in some cases striated. 



Beyond Lyne Edge to the base of Harrop Edge, where the millstone 

 grit appears, are strong marls, with sand and gravel beds beneath. In the 

 marl a few feet below the soil are boulders, smooth and well rounded, con- 

 sisting of andesitic ash, rhyolitic breccia, Eskdale granite, vein rock, 

 and crushed altered ash. 



Along the base of Shaw Moor the boulder clay is upwards of 

 30 ft. thick, containing a variety of small boulders, pieces of gannister, 

 &c. One large boulder, a felsite from the Lake district, is upwards of 

 seven tons in weight ; another is rather smaller in size, a felsite with 

 epidote, also from the Lake district ; another is about thirty hundred- 

 weight, and is a Criffel granite from the S.W. of Scotland. 



The boulder clay from the river Tame to the base of the hills, from 

 Millbottom to Micklehui'st, consists of boulder clay resting upon sand, 

 and gravel, from which a good supply of water can bo readily obtained. 



The clay contains a large number of small boulders, often intermixed 

 with thin bands of sand and small gravel, and occasionally larger boul- 

 ders of the Eskdale series : andesitic ash (crushed), felsites, syenite, 

 vein rock, and hornblendic granite from Buttermere. These are 

 rounded, smooth, the softer portions showing slight striations.
