Although rainfall stations are not numerous on the hills of north 

 Derbyshire, Dr Mill {vide Linton, 1903 : 3) thinks that " average 

 falls exceeding fifty inches (127 cm.) in the year occur at several 

 points in the high ground ; but it is unlikely that so great a 

 rainfall as sixty inches (152 cm.) is reached."

Smoke 



The district, lying as it does between the great coalfields 

 and manufacturing districts of south Lancashire, and south-west 

 Yorkshire, possesses an atmosphere which is frequently vitiated 

 by smoke. The greasy soot settles on the leaves and stems of 

 plants, and gives them a permanently dirty appearance. A clean 

 expanse of white snow on the hills is often palpably blackened 

 in two or three hours' time. Mr A. Wilson (1900) has stated 

 that "the great smoke drift from south and east Lancashire 

 could be seen crossing the Pennine Range of moorlands, and 



^ 10 inches = 25-4 centimetres.
