Summaries "'^ study of the tal)le showing a summary of resuUs of 

 inspection of complete fertiHzers reveals the fact that 

 out of the 282 distinct brands analyzed, iio or about 39 per cent of 

 the whole number fell below the manufacturer's guarantee in one or 

 more elements. Ninety-eight brands were deficient in one, 10 in 

 two and 2 in all three elements. Twenty-nine brands were defi- 

 cient in nitrogen, 57 in potash and 38 in phosphoric acid. The 

 deficiencies in many of these brands were made up by an excess of 

 some of the other elements so that only 17 out of the 284 brands 

 analyzed showed a commercial shortage. This shortage ranged from 

 a few cents to $3.36 cents per ton ; only eight brands showed a com- 

 mercial shortage of over $1.00 per ton. ^This certainly shows a 

 much better condition than existed during the previous year. 



Out of the 34 samples of ground bone, tankage, and dry ground 

 fish analyzed, 5 showed a deficiency in nitrogen and 6 in phos- 

 phoric acid ; only one of these brands, however, showed a commer- 

 cial shortage. 



The average retail cash price, valuation, and percentage of dif- 

 ference of the ground bone, dissolved bone, tankage and dry ground 

 fish are as follows : 



Average retail 

 cash price. 



Ground bone, $30.08 



Dissolved bone, 29.33 



Tankage, -7-5° 



Dry ground fish. 39-oo 



* In excess of selling price. 



In the chemicals and raw materials furnishing nitrogen, only one 

 sample of cottonseed meal failed to meet the guarantee. Three 

 samples of dissolved bone black and two samples of acid phos- 

 phate failed to meet the guarantee in available phosphoric acid. 

 Among the potash compounds one sample of high grade sulphate, 

 five of muriate and one of carbonate failed to meet the potash 

 guarantee. 



The various agricultural chemicals and raw materials as sold at 

 retail in our local markets, have furnished nitrogen, phosphoric acid 

 and potash to the consumer at the following prices :
