conscientiously performing tlieir duties. The result of the 

 year's work may be sunmiarized as follows : — 



(«) Testing of Glassware. — Each piece of glassware found 

 to be correct has the words "Mass. Ex. Sta." etched on. 

 There were examined 3,082 pieces, of which 204, or 6.62 per 

 cent., were condemned. 



[h) Examination of Candidates. — Twenty-one candidates 

 were examined during the year 1907. Most of those present- 

 ing themselves for examination had a fair understanding of the 

 process, although it was freqnently necessary to refuse certifi- 

 cates, insist on further preparation and a second examination. 

 It is believed that the station would 1)e false to its trust if it 

 allowed candidates to pass who did not have a satisfactory 

 theoretical and practical understanding of the method of pro- 

 cedure. 



(c) Inspection of Bahcock Machines. — The annual inspec- 

 tion of Babcock machines was made in November of 1907. Of 

 the 36 places visited, 22 were creameries, 11 milk depots, 2 

 city milk inspectors and 1 a chemical laboratory. Sixteen of 

 the creameries were co-operative and 5 were proprietary or 

 managed by stock companies. The 11 milk depots in opera- 

 tion were in every case proprietary. 



Thirty-seven machines were inspected, of Avhich 2 were con- 

 demned and 1 was found needing additional heat. The machines 

 in use are 14 Facile, 9 Agos, 6 Wizard, 5 Electrical and 2 

 Stoddard. 



The glassware as a whole was clean, but a few still use very 

 dirty bottles and 3 were found using untested glassware. Fol- 

 lowing is a list of creameries and milk depots now in operation 

 that pay by the Babcock test : — 



Creameries.
