favor on this department by uotiljiug 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 would be greatly appreciated. In all cases of failure to find a 

 brand on the market, the analyses were made on the manufacturer's 

 sample as indicated in the tables of analyses. 



RESULTS OF INSPECTION. 



A study of the tables of analyses following shows that of the 177 

 samples analyzed, representing 145 brands, 77 (44%) as below guaran- 

 tee* in one or more constituents. Fifty-one (29%) are below guarantee 

 in nitrogen, 14 (21%) in available phosphoric acid and 40 (23%) in 

 potash. Twenty -one (12%) are below guarantee in nitrogen and potash. 

 12 (7%) in nitrogen and available phosphoric acid, 9 (5%) in potash 

 and available phosphoric acid and 7 (4%) in nitrogen, available phos- 

 phoric acid and potash. 



Nineteen brands (13%) fail to furnish a commercial equivalent of the 

 constituents guaranteed. Of these, nine are sold by the Buffalo Fertil- 

 izer Company and three by the Chicago Fertilizer Co. The other seven 

 brands failing to furnish a commercial equivalent are distributed among 

 six companies. The facts revealed by the analyses of the goods of the 

 Bufi'alo Fertilizer Co., and the Chicago Fertilizer Co., demand that 

 special attention be called to them. 



Buffalo Fertilizer Co.: It is a significant fact that the only brand 

 sold by this company which furnished a commercial equivalent was 

 Muriate of Potash a material not manufactured by the company. 



Ammoniated Bone Black. Three samples of this brand were drawn 

 from difl'erent localities all of which were quite similar in appearance. 

 Sample 1340 is below guarantee in nitrogen and above in available 

 phosphoric acid and potash. Sample 1485 furnishes a little more than 

 one-half of the nitrogen, a little better than three-fourths of the available 

 phosphoric acid and a trifle more than the potash guaranteed. Sample 

 1503 furnishes three-fourths of the nitrogen guaranteed and is hardly 

 up to the requirements for available phosphoric acid and potash. 



Bone Meal. Only one sample of this brand was found on the markets. 

 It is more than one per cent below guarantee in nitrogen and just meets 

 the guarantee for phosphoric acid. It fails to furnish a commercial 

 equivalent. 



Celery and Potato Special. Four samples of this brand were drawn 

 from different localities, no two of which are alike either in physical 

 appearance or chemical analyses. Sample 1398 furnishes a trifle more 

 than two-thirds of the nitrogen, a little better than three-fourths of the 

 available phosphoric acid and a little more than four-fifths of the potash 

 guaranteed. Sample 1480 furnishes less than one-half of the nitrogen, 

 a little more than five-eighths of the available phosphoric acid and a 

 trifle more than one-half of the potash guaranteed. Sample 1487 fur- 

 nishes seven-tenths of the potash guaranteed and is above in available 

 phosphoric acid. Sample 1488 furnishes a little more than two-thirds 



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

 phoric add or pota.sh is considerefi below guarantee.
