The object in obtaining these data was to secure, as nearly as pos- 

 sible, a complete, practical record of the operating characteristics of a 

 standard cold room of the dry air type. Much credit is due the co- 

 operating farmer for the diligence and care in making the readings. 



Data on four principal factors were obtained; namely (1) outside air 

 temperature; (2) cold room interior temperature, taken at a mid-point 

 in its height; (3) current consumption in kilowatt-hours; and (4) the 

 quarts of milk and cream stored. The average temperature referred to 

 in the chart is the average of the day's readings. 



On account of practical difficulties in making the observations, no 

 data were taken on the moisture content of tlie air which also has 

 an importance in the results obtained. 



April. The equipment was installed and placed in operation the 

 first of April, 1926, as indicated in the curves for that month. Up to 

 the twentieth of the month the outside temperature was quite variable, 

 ranging from 25° to 47°. During the same period the cold room or 

 refrigerator temperature remained between 30° and 35° after the first
