temperature by one degree over the outside air temperature. 



The average difference between outside and inside temperatures was 

 found to be approximatelv 18° in 1926 on Farm No. 2; 20" on Farm 

 No. 4 and 19" on Farm No. 1. 



Current Consumption per 100 qts. of Milk and per Cow. The current 

 consumption per 100 cjuarts of milk is figured in Table 8 on the total 

 estimated milk produced in twelve months, and on the milk liandled 

 during the period that artificial refrigeration was necessary. 



Accurate records of the quantity of milk placed in cold storage were 

 not attempted on Farm No. 2, and the daily average quantity of 300 

 quarts has been used. The milk route takes an average of 280 quarts 

 per day, and 20 quarts extra was carried for emergencies. All of this 

 300 ciuarts is carried in cold storage, the greater part for 20 hours and 

 the rest for 12 hours. The delivery truck leaves at -4: 00 A. M. so that 

 morning's milk (milked at 5:30 A. M.) must be held over.' On this 

 basis the farm handles at least 110,000 quarts of milk a year. 



Likewise no record of the variations in the number of cows milked 

 from day to day has been kept, and the milking herd as a whole has 

 been considered. Inasmuch as this farm keeps the milking string up 

 by buying fresh cows, rather than raising young stock, this figure should 

 be reasonably accurate.
