202 STATE BOARD OF AGRICULTURE. 



and consequently it is only by chance that samples of such goods are 

 obtained. If persons ordering goods in this way wish to have them in- 

 spected they will protect themselves and at the same time confer a 

 favor on this department by notifying us, and upon the arrival of the 

 goods an inspector will be sent to draw samples. 



It is the desire of this department to make the inspection as complete 

 as possible, and any information to further this end, from dealer or con- 

 sumer, will be greatly appreciated. In all cases of failure to find a 

 brand on the market, the analysis was made on the manufacturer's 

 sample as indicated in the tables of analj'ses. 



RESULTS OF INSPECTION. 



A study of the tables of analyses shows that, of the 249 samples 

 analyzed, representing 230 brands, 26 (10%) are below guarantee* in 

 one or more constituents. Fourteen (5.G%) are below guarantee in nitro- 

 gen, 4 (1.6%) are below guarantee in available phosphoric acid, 2 (0.8%;) 

 are below guarantee in total phosphoric acid and 15 (6%) are below 

 guarantee in potash. Six (2.4) are below guarantee in nitrogen and 

 potash, 1 (0.5%) in nitrogen and available phosphoric acid. 



While there are, as stated above, 34 samples falling below guarantee 

 in one or more constituents, there are, however, only 3 (1.2%) that are 

 more than 75 cents per ton below their guaranteed commercial value. 

 That is, the shortage in one constituent is compensated by an excess 

 of the guarantees in the other constituents. This is a very satisfactory 

 showing. 



SCHEDULE OF TRADE VALUES. 



In accordance with the custom adopted and followed in previous 

 years, the following schedule of prices for determining the commercial 

 valuation of a fertilizer is published : 



Nitrogen 16y2C per pound 



Potash soluble in water 4y2C " " 



Available phosphoric acid 5c " " 



Total phosphoric acid in bone 4c " " 



Insoluble phosphoric acid in fertilizers 



containing nitrogen 2c " " 



In fertilizers containing no nitrogen no value is given to insoluble 

 phosphoric acid. The valuation of a fertilizer is determined as follows: 

 The percentage or pounds per hundred of each ingredient (nitrogen, 

 available phosphoric acid, insoluble phosphoric acid and potash) is mul- 

 tiplied by 20, giving the number of pounds of each ingredient in a ton. 

 These figures are then multiplied by their respective pound prices. 



In the last column of the table of analyses headed ''Valuation" is 

 given the commercial valuation of the samples, as guaranteed and as 

 found, based upon the prices quoted above. 



*A shortage of more than 0.10 per cent of nitrogen of more than 0.20 per cent of available phos- 

 phoric acid or potash is considered oelow guarantee.
