248 AMERICAN DAIRYING. 



It first shows the defects of the old gauge 

 system, which I have already written about. 

 The apparatus for weighing and sampling the 

 cream is illustrated, and consists of a pail 

 eight inches in diameter and twenty-two inches 

 deep, a spring balance, a sampling tube, collect- 

 ing bottles for the driver to bring samj^les of 

 each patron's cream at each trip, and the com- 

 posite sample bottle, which may be a half-pint 

 jar. Instructions for sampling and weighing 

 are given. Bichromate of potash is recom- 

 mended as a preservative of the composite 

 samples. An 18 c. c. pipette is used to meas- 

 ure the cream for testing. The test bottle used 

 is graduated from to 30, having a large neck, 

 it being made to test cream. The acid, the 

 acid measure and the centrifugal machine are 

 the same as used in testing milk, and the work 

 of testing is practically the same as in testing 

 milk. 



The bulletin contains six very interesting 

 and instructive tables showing the variations 

 in cream from different patrons, besides much 

 valuable information for persons operating 

 gathered-cream creameries, and they should 

 secure a copy of it if possible.
