 Miscellaneous Work 



Feed ControL (P. H. Smith, A. F. Spelman, G. J. Larsinos, F. A. Mc- 

 Laughlin, J. T. Howard). During the fiscal year, 1,591 samples of feeding stuffs 

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

 show that at least 96 per cent of the samples collected varied less than one per 

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

 from the registration of feeding stuffs in 1931 (calendar year) were $21,320, 

 derived from 1,066 brands at $20 each. 



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

 October 1, 1930, to October 1, 1931, the seed laboratory analyzed 1,135 samples 

 of seed, of which 469 were collected by the State Commissioner of Agriculture, 

 216 sent in by dealers and farmers, 212 received from the Rhode Island Com- 

 mission of Agriculture, and 238 purchased from wholesalers for special tests. 

 Classification of these analyses is shown by the following summary.
