Feed Control. (P. H. Smith, A. F. Spelman, J. W. Kuzmeski, F. A. McLaughlin, 

 J. T. Howard.) During the fiscal year, 1,641 samples of feeding stuffs were offi- 

 cially collected and examined in the control laboratories. The results show that 

 at least 94 percent of the samples collected varied less than 1 percent from stated 

 guarantees in protein, fat and fiber content. The gross receipts from the regis- 

 tration of feeding stuffs in 1934 (calendar year) were $21,400, derived from 

 1,070 brands at $20 each. 



Seed Control. (P. H. Smith, F. A. McLaughlin, Margaret E. Nagle.) From 

 October 1, 1933, to October 1, 1934, the seed laboratory analyzed 1,627 samples 

 of seed, of which 768 were collected by the State Commissioner of Agriculture, 

 482 sent in by dealers and farmers, 185 received from theRhodelslandCommissioner 

 of Agriculture, and 192 purchased from wholesalers for special tests. Classifica- 

 tion of these analyses is shown by the following summary.

 oratory. 



Field tests to determine trueness to type were again conducted in cooperation 

 with the Department of Vegetable Gardening which tested 192 samples of sweet 

 corn and 187 samples of vegetable seed. 



Dairy Law. (P. H. Smith, J. T. Howard, H. L. Allen.) During the year ending 

 December 1, 1934, 6,227 pieces of Babcock glassware were tested. Condemned 

 glassware consisted of one milk-test bottle and one pipette. One hundred and nine 

 certificates of proficiency were awarded. 



Two hundred and nineteen creameries, milk depots and milk inspectors' lab- 

 oratories were visited in order to check methods and pass upon equipment in 

 use. As a result of this inspection, two machines were condemned, and repairs 

 were ordered on nineteen. Seven plants were re-inspected to approve repairs. 



This act has been amended to give to the Commissioner of Agriculture con- 

 current power in its enforcement. Through an arrangement with his office the 

 experiment station will continue to test glassware, issue certificates of proficiency, 

 and make the annual inspection of machines and apparatus. The Commissioner 

 through his deputies will conduct all check tests where methods or accuracy are 

 in question. 



Advanced Registry Testing. (P. H. Smith.) Advanced registry testing has 

 been supervised by this department since its beginning in 1902. There are now 

 on yearly test 321 cows located on 42 different farms. This does not include 

 the herd tests where all animals in each herd are placed on test. Of these there
