uance of home equipment it would be natural to expect the quality of 

 the curve to reflect the use in any home, whether city or farm, and it 

 is this characteristic use of appliances in this home, together with the 

 absence of refrigeration, which is the principal cause of the failure to 

 develop a peak load in midsummer. 



This suggests that while the building of the load in the farm home 

 may develop the total gross load, it may not develop a quality of load 

 which blends with urban and commercial load curves of the central 

 station to give a greater evenness of current production throughout the 

 year, thereby losing one of the possible qualities of rural electrification. 

 Tf duplicated on other farms, the net benefit to the electrical industry 

 would be an increase of total current generated with qualities similar 

 to the present city load. No evening effect on the total generation 

 curve would result ; in fact the usual late fall, winter and early spring 

 peaks of the plant production curve would be increased and the mid- 

 summer depression more accentuated. 



The curves bear a considerable degree of resemblance with each other 

 in general characteristics and indicate a standard and stabilized rou- 

 tine which is the usual quality to be expected of farms in general. The 

 tendency with this character of load is to run into peaks in March, April 

 or May and in the late fall, with a depression between. 



Twenty-four per cent, of the load has maximum use in cold weather 

 while only 13.5% tends toward a summer peak, so that considerable 

 reason for the midsummer slump is evident (refer to Table 8). 



While this is a wholesale dairy farm, no electrical refrigeration was 

 used for cooling or storing the milk during this period. Neither was 

 electric refrigeration used in the house. The absence of this applica- 

 tion will be immediately observed by comparing the curves with those 

 of the three other dairy farms, Nos. 1, 2, and 4, where it was in use. 



It is also of interest to observe that while only 12.5% of the equip- 

 ment investment was for farm operations proper, this small per cent, 

 consumed 66% or % of the electricity per year and included only the 

 barn lights and milking machine. The latter contributed the bulk of this, 

 or 59%, but since this machine is used daily to the same extent, it pro- 

 duces no effect on the contour of the curve. Its principal value is in 

 developing a large quantity use. This serves to indicate that one good 

 farmstead application, properly applied, may easily surpass the entire 

 household load and that continued emphasis should be placed on the 

 development of applications in the farm work group. 



The failure of this farm to develop the expected annual curve con- 

 tour lies in the negative qualities of the large amount of household 

 equipment plus the same quality in the milking machine, and, lastly, the 

 absence of household and dairy refrigeration. In other words, the 

 equipment employed and methods of use produce negative or erratic 

 qualities, and there is little that reflects the busy summer season. 



Whereas most combination ranges are expected to have the electrical 

 section in greater use in the warm weather, such did not prove to be 

 the case in this instance, due to the particular design of this range, 

 which was provided with an oven heated from the firebox with an ad- 

 ditional electric oven as well. (The average combination, such as the type
