to growers in the field and tested out with success. Motion pictures have been 

 very helpful in studying detailed operations in certain tasks and also furnish an 

 effective means of presenting results to growers. 



Live Stock Management, Methods and Costs. (J. A. Foord.) The 

 positive reactors to the blood test for Bangs disease from the college herd have 

 been kept in loose pens for three years, being "tied up" only for milking and grain 

 feeding. The method has shown advantages in reduced hours of labor and amount 

 of equipment needed, although with somewhat higher costs for bedding. Pro- 

 duction has been well maintained, and clean milk of low bacterial count produced. 

 Very little more floor space is needed than in the better type of stable. The method 

 is worthy of consideration by practical dairymen. 



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, G. J. Larsinos, J. W. Kuz- 

 meski, F. A. McLaughlin, J. T. Howard.) During the fiscal year, 1,607 samples 

 of feeding stuffs were officially collected and examined in the control laboratories. 

 The results show that at least 97 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 1932 (calendar year) were 

 $21,200, derived from 1,060 brands at $20 each. 



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

 October 1, 1931, to October 1, 1932, the seed laboratory analyzed 1516 seed 

 samples, 463 of which were collected by the State Department of Agriculture, 

 304 sent in by dealers and farmers and 194 by the Rhode Island Department 

 of Agriculture, 354 purchased from wholesalers for special tests. The remaining 

 201 were accounted for in tests of ingredients of grass seed mi.xtures, some mix- 

 tures containing as many as eight ingredients.
