= 1160 pence. The wool will yield 50 per cent., and there are 

 9 Ib. of top to every i Ib. of noil, therefore

per lb. = 80 pence 



The cost of combing the 45 lb. of top at 2\ pence per lb. 

 is 101-25 pence. The money we get for the 5 lb. of noil 

 underpays the combing charges 21*25 



101-25 pence = Combing charges 

 80-00 = Value of 5 Ib. of noil 



21-25 pence ; 



therefore this amount has to be added to the cost of the greasy 

 wool. Sometimes when combing tender and shabby wools, the 

 percentage of noil is high, and overpays the combing charges ; 

 in this case the amount in excess of combing charges would be 

 subtracted from the cost of the greasy wool.
