Feed Inspection. 



Three hundred and forty-nine samples of commercial feeding stuffs were 

 analyzed for the State Department of Agriculture in connection with the en- 

 forcement of the state law regulating the sale of these materials. The results of 

 this inspection are reported in Bulletin No. 213. The relative number of feeds 

 in the respective classes is similar to that of the past two seasons, except that 

 the relative number of cotton seed meals and poultry feeds is slightly higher. 

 More feeds were deficient in protein and in fat than in any of the preceding four 

 years. The compounded feeds, cotton seed meals, dairy feeds and poultry 

 feeds show the largest number of deficiencies. The cotton seed meals were 

 decidedly inferior in quality. 



Inspection of Commercial Fertilizers. 



One hundred and fifteen samples of commercial fertiliz'ers were analyzed 

 for the State Department of Agriculture. The results of this work are reported 

 in Bulletin No. 214. There was a slightly higher proportion of high analysis 

 fertilizers than last year, but the number of deficiencies in guaranteed analysis 

 was slightly greater. 



Seed Testing. 



A new seed laboratory was fitted up in the spring of 1924. An air blast 

 machine for separating Ught seeds was purchased, together with new micro- 

 scopes, balances, tables, and other equipment. A large new germinating 

 chamber equipped for alternating temperatures was also constructed. While 

 the laboratory is small, it is now well equipped for careful and accurate work. 



During the season 510 samples of seeds were handled by the laboratory, 

 about half of which were ofl[icial inspection samples taken by the State Depart- 

 ment of Agriculture. The remainder were from farmers, county agents, and 

 seed dealers.
