cost of $26,003. This would mean an annual saving of .000487 per quart, 

 and $14,658 per year.

Only a small number of the companies in Rochester operate an engine 

 room and boiler, and a still smaller number operate a refrigeration plant. 

 These charges have been combined for the purpose of determining the 

 total expense for the operation of all of these plants in Table No. 62.

The total number of quarts of milk in Rochester which is distributed 

 by companies operating engine rooms and by companies operating refrig-

 at a cost of .001009 per quart. The yearly cost of operating these plants 

 under present conditions is $20,319.55. 



An inspection of the figures in Table No. 62 shows great variation in 

 the cost per quart and in the number of quarts per man hour. Factories 

 Nos. 1 and 8 had a large ice cream business in addition to their milk,

 of operating the entire plant are therefore larger than they would be for 

 milk alone. Plants Nos. 3, 5 and 6 are comparatively small, and are 

 equipped with power machinery and refrigerating machinery which be- 

 cause of its small size cannot give the economies that would be obtained 

 from machinery large enough to furnish power and refrigeration for the
