New YorkK AGRICULTURAL EXPERIMENT STATION. 13 
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, 6.2 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. 
The mspection of conmercial 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 1900 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 
etock keeper if he continues to buy cattle foods freely, These 
mixtures are inferior in quality in most instances and are sold at 
prices relatively too high. 
Inspection of Paris green and other insecticides.—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 58.10 per
