We lijive bought during the past years, creamery butter milk con- 

 taiuiug from 7 to 8 per cent, of solids at 1.37 cents per gallon. (See 

 third annual report, page 42.) Our own skim milk, with 9.5 per 

 cent, of solids would represent on that basis, a value of 1.75 cents 

 per gallon, or .44 cents per quart.
