PART III. 



The Upper Coal Measures. < 



The Upper Coal Measures of Lancashire occupy a limited 

 surface area, to the south of the richer middle series. They 

 occur in small patches in the Wigan area, and in the neigh- 

 bourhood of Leigh, Worsley and Pendleton on the west of 

 Manchester. The main development is, however, on the east 

 and north of Manchester itself. The basement strata of the 

 series in the Ardwick district contain several seams of coal 

 which were worked over thirty years ago. It is to these 

 productive measures of the upper series that the term 

 *' Manchester Coalfield " has been applied. 



The uppermost beds of the series were very little known 

 until the construction of the railway line from Fallowfield 

 to Levenshulme and Longsight. 



Prior to this, our knowledge of the upper beds was mainly 

 limited to the published papers by Binney and others upon 

 the Collyhurst section, which was opened in 1861 when the 

 British Association visited Manchester. 



The sections exposed in the railway cutting from Fallow- 

 field to Levenshulme were worked over in the greatest detail
