180 AMERICAN DAIRYING. 



vania Experiment Station made power tests of 

 separators at their dairy school in 1894. 



Value of station work. — I consider the tests 

 of separators at our dairy schools of great value. 

 There is no more reliable source of information. 

 It is right in the line of work that they were 

 created to perform- and they are doing us good 

 service that is sure to be appreciated more and 

 more as the years go by and they develop as 

 they are sure to do. I have just received "Bul- 

 letin No. 22" of the Iowa Station, in which 

 Prof. Henry C. Wallace gives the results of 

 work done with separators during the six 

 months ending June 10, 1894. The work done 

 by four separators is reported. The per cent of 

 fat- in the skim-milk was as follows: 



One separator with 61 trials showed an aver- 

 age fat in skim-milk of .06. 



One with 52 trials showed an average fat. in 

 skim-milk of .07. 



One with 22 trials showed an average fat in 

 skim-milk of .22. 



One with 54 trials showed an average fat in 

 skim-milk of .08. 



Prof. Wallace says: "It should be remem- 

 bered that the tests were made by dairy stu- 

 dents during the course of their instruction and 

 consequently do not represent the best work 

 that can be done with these machines, although 

 perhaps fairly representing the work done in
