Notes on the Use of the Home Separator. 987 



This is a sample of the loss which is taking place on the above 

 dairy farms yearly. Assmning thnt the average excess of fat in the 

 skim milk is '1 per cent., and that the quantity of milk put through 

 the private separator is 7,728,000 gallons yearly the actual loss of fat 

 would be 73,329 lbs. It will be seen by the above that there is a 

 serious leakage of the dairymen's profit in this direction, and very 

 often this discrepancy is attributed to the factory manager who treats 

 the cream, and not to its proper source — the separator. 



I have a few special lots here which I did not include in the 

 above average, but which I will give you for your own information. 



No. 1 tested ... ... ... 1-4 % 



No. 2 „ 2-6% 



No. 3 „ ... ... ... -8 % 



Factory managers might do a lot to obviate that loss by encourag- 

 ing their suppliers to send in samples of skim milk frequently to be 

 tested. Variations of the butter fat contents of the cream would be 

 often traceable to this source, and if it could be clearly proved to the 

 suppliers that this was the case much more pleasant relations would 

 exist between factory managers and cream suppliers.
