464 MR. BINNEY ON DRIFT-DEPOSITS NEAR MANCHESTER. 



facts, which he intended to publish when he had completed 

 his collection ; but these did not show one bed of clay or 

 marl which could be called Upper Boulder-clay, but several ; 

 in fact, there were numerous intercalations of it in the sand 

 and gravel, one of which he had seen occurring at Kersall 

 Moor, entirely surrounded by sand. To show the com- 

 plexity of these deposits, and the difl&culty of reducing 

 them to two beds of Till or Boulder-clay, he gave two sec- 

 tions, one near Hyde and the other at Outwood*, where 

 the following were met with > —

From the position of the Outwood section, in a slight 

 depression, and the higher grounds adjoining being capped 

 with a bed of clay containing pebbles, 8 or 10 feet in 

 thickness, another deposit of clay should be placed on the 

 top. Thus in one case there are 6 beds of Boulder-clay, 

 and in the other only 3. These are two of the many in- 

 stances which could be adduced, and suggest caution in 

 attempting to classify these deposits without collecting 

 and consulting numerous sections.

 win, mining engineer, Hyde and Haughton Collieries.
