Nearly every dairy farmer has a mowing machine anyway, and in cases where 

 the silage corn acreage is not sufficient to justify the purchase of a binder, the 

 mower may prove to be the most economical method of harvesting. 



FEED CONTROL SERVICE 



Philip H. Smith in Charge 



The Feed Control Service comprises not only feed inspection, but several other 

 activities, as listed below: 



Feed Control (General Laws, 1920, Chapter 94) 

 Seed Control (General Laws, 1927, Chapter 94) 

 Dairy Law (General Laws, 1920, Chapter 94) 

 Advanced Registry Testing 

 Miscellaneous Work 



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

 lin, J. T. Howard.) During the fiscal jear, 1,649 samples of feeding stuffs were 

 officially collected and examined in the control laboratories. The results show 

 that at least 97.7 per cent of the samples collected varied less than 1 per cent 

 from stated guarantees in protein, fat and fiber content. The gross receipts 

 from the registration of feeding stuffs in 1933 (calendar year) were $20,860, 

 derived from 1,043 brands at $20 each. 



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

 October 1, 1932, to October 1, 1933, the Seed Testing Laboratory analyzed 1188 

 seed samples, 507 of which were collected by the State Department of Agriculture, 

 180 submitted by dealers and farmers and 191 by the Rhode Island Department 

 of Agriculture, 266 purchased from wholesalers for special tests, and the re- 

 maining 44 accounted for by germination tests of ingredients of grass seed mixtures.

*266 field tests are duplications of laboratory tests, portions of the same samples being used. 



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

 with the Department of Vegetable Gardening, which tested 266 samples of 

 sweet corn.
