An analysis of the foregoing tables reveals the following 

 facts : — 



1. Sixty-nine per cent of the total tonnage sold was made 

 up of mixed goods, and 31 per cent of chemicals and unmixed 

 fertilizer by-products. 



2. Of the 37,579 tons of mixed goods sold, 93 per cent were 

 complete fertilizers and 7 per cent were ammoniated super- 

 phosphates and superphosphates with potash. 



3. Of the 35,007 tons of mixed complete fertilizers, about 

 73 per cent were high analysis (14 per cent or over of available 

 plant food) and 27 per cent low analysis fertilizers (less than 

 14 per cent of available plant food). 



4. The 25,462 tons of high analysis complete fertilizers were, 

 with the exception of 233 tons, furnished by thirty-five grades 

 of fertilizer, that is, formulas having their plant food present 

 in various proportions. About 88 per cent of the total tonnage 

 of the high analysis mixtures was furnished by eleven grades of 

 fertilizer, and about 79 per cent of the balance was furnished 

 by thirteen other grades; or, expressed in another way over 97 

 per cent of the total tonnage of high analysis fertilizers was 

 furnished by twenty-four grades. 



5. The 9,445 tons of low analysis fertilizers were, with the 

 exception of 120 tons, furnished by eighteen grades of fertilizer, 

 and over 94 per cent of this tonnage was furnished by ten 

 grades of fertilizer. 



G. In case of the ammoniated superphosphates, of the 2,278 

 tons sold, over 86 per cent were low analysis goods. The 

 tonnage of high analysis ammoniated superphosphates was 

 furnished by one grade, and 87 per cent of the tonnage of the 

 low analysis was furnished by seven grades. 



7. Thirty-six per cent of the total tonnage of mixed fertilizer 

 was derived from grades recommended for the East by the soil 

 improvement committee of the National Fertilizer Association; 

 and over 64 per cent of the total tonnage deviated by 1 per 

 cent only, in nitrogen, phosphoric acid, or potash, as the case 

 might be, from grades thus recommended. 



8. With reference to chemicals and crude stock materials, 

 the distribution of the tonnage was as follows: about 57 per 

 cent of the total tonnage was nitrogen products; about 26
