EXPERIMENT STATION. 



[Jan. 



All candidates are refused a certificate who fail to show profi- 

 ciency in manipulation or who do not have a good working 

 knowledge of the principles underlying the test. Eight candi- 

 dates passed the examination at the first trial, and 2 certificates 

 were withheld until further proficiency was acquired. The idea 

 has been prevalent that the experiment station gives instruction 

 in Babcock testing. Such is not the case ; all candidates must, 

 before presenting themselves for examination, have acquired a 

 thorough knowledge of the test. 



(2) Examination of Glassware. — During the past year 

 4,047 pieces of glassware were examined, of which 41 pieces, 

 or 1.01 per cent., were inaccurate. This is the lowest percent- 

 age of inaccuracy found during the ten years that the law has 

 been in force. Following is the summary of the work for the 

 entire period : — 



The passage of this law has prevented 1,885 pieces of inac- 

 curately graduated glassware, representing 6.34 per cent, of 

 the entire number tested, from coming into use. 



(3) Inspection of Bahcock Machines. — Since the 1909 in- 

 spection 1 creamery has suspended operations. During the 

 present inspection, recently completed, 28 places were visited, 

 of which 15 were creameries, 12 milk de])ots and 1 a chemical 

 laboratory. Ten of the creameries were co-operative and 5 



' Average.
