cent of the total cost. " Other costs," inckiding depreciation on the 

 herds, amounted to 30.3 per cent. This shows that calves and ma- 

 nure failed by a small margin to equal the cost of labor and by a 

 wide margin to balance the "other costs," including depreciation 

 on the herds. 



AVERAGE COMPARED WITH BULK-LINE COSTS. 



If the net cost of producing milk on various farms is tabulated in 

 an ascending scale, together with the percentage of the whole quan- 

 tity of milk produced at these separate costs, one or possibly more 

 points will be shown at or below which a large proportion of the 

 milk is produced. The point or line of demarcation selected is called 

 the " bulk " line. It is usually placed where it will include between 

 80 and 90 per cent of the volume of milk produced.
