The retail selling? price of complete fertilizers averages |25.71 

 a ton, while the retail cost of the separate ingredients, unmixed, 

 averages |19.81, or |5.90 a ton less than the selling price. The 

 average cost of one pound of plant-food in mixed fertilizers to 

 consumers is as follows: nitrogen, 20.8 cents; available phos- 

 phoric acid, 6.3 cents; potash, 5.9 cents. 



In 1901, 82 manufacturers paid license fees on 550 different 

 brands of fertilizers. The requirement of a license fee has 

 reduced the number of brands offered for sale from 2,268 to 550. 



Tlic inspection of commercial feeding- stuffs. — The outcome of 

 the inspection of feeding stuffs is given in Bulletin No. 198. 

 It is shown that 92 manufacturers complied with the law by 

 registering the guaranteed composition of 126 brands, and pay- 

 ing the required license therefor. * Sixty-six of these brands were 

 standard feeding stuffs having more or less fixed or definite char- 

 acteristics, while 60 were feeds compounded from various manu- 

 facturing offals, the majority of which contained some inferior 

 ingredient. 



The analyses of 297 samples taken by representatives of the 

 Station are reported, representing 98 brands inspected in the 

 fall of 1,900 and 101 brands found in the winter of 1901. 



The unmixed or standard goods were found to be of fairly 

 uniform quality and practically as good as the guarantees, 

 except in a single instance. The discrepancies occurred with the 

 mixed goods, many of which contained oat hulls, as shown by 

 the percentage of crude fibre present. 



Adulteration of corn meal and other grain products appears to 

 be practiced. On the whole, it can be said with good reason 

 that the compounding of feeds and the use of inferior materials 

 for adulteration is a serious menace to the prosperity of the 

 Ktock keeper if he continues to buy cuttle foods freely. These 

 mixtures are inferior in quality in most instances and are sold at 

 prices relatively too high. 



Inspection of Paris green and otlicr insocticides. — In forty sam- 

 ples of Paris green examined, the amount of arsenious oxide 

 varied from 56.13 to 62.87 per ct., with an average of 58.1U per
