A study of the preceding table, showing a summary of the 

 results of the inspection of complete fertilizers, reveals the fact 

 that out of the 282 distinct brands analyzed, 110, or about 39 

 per cent, of the whole number, fell below the manufacturers' 

 guarantee in one or more elements. Ninety-eight were deficient 

 in one, 10 in two and 2 in all three elements. Twenty-nine 

 brands were deficient in nitrogen, 57 in potash and 38 in phos- 

 phoric 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 282 brands analyzed showed a commercial shortage.
