conscientiously performing their duties. The result of the 

 year's work may be summarized as follows : — 



(a) 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.(32 per 

 cent., were condemned. 



(b) 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 frequently necessary to refuse certifi- 

 cates, insist on further preparation and a second examination. 

 It is believed that the station would be 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 Babcoch 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 which 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 : —
