Analyses of commercial fertilizers, M. A. Scovell and H. E. Curtis {Ken- 

 tuck ij Sta. Bui. 109, pp. 117-191). — "There were 331 different brands of commercial 

 fertilizers registered from January 1 to August 22, 1903. Of these different brands 

 192 were complete fertilizers, or fertilizers containing all three of the essential ingre- 

 dients, namely, phosphoric acid, nitrogen, and jiotash; 33 were acid phosphates, or 

 superphosphates; 10 contained a mixture of acid phosphates and nitrogen com- 

 pounds only; 44, acid phosphate and potash salts only; and 52 were classed as bones 

 or tankage. 



"Two hundred and sixty-seven samples were collected by deputy inspectors, or 

 were sent by farmers from various parts of the State. Three hundred and thirty-one 

 samples were those sent in by firms as official samples. Of these samples 519 were 

 analyzed by the station. 



"The results of the analyses show that of the 519 samples analyzed, 89, represent- 

 ing 79 brands and 29 firms, fell so far below the guaranteed analyses in jihosphoric 

 acid, nitrogen, or potash, or any two, or all three of these ingredients, that the defi- 

 ciencies could not be accounted for by variations in sampling or analj'sis. It is 

 probable that in most cases variations can be accounted for by hurried or careless 

 mixing at the factories, or gross mistakes in shipping one brand for another, but in 

 one or two instances the results show a desire on the part of the manufacturer to 

 guarantee a higher percentage of the essential ingredients than the goods contain." 



Analyses of commercial fertilizers and manurial substances, C A. Goess- 

 MANN {Massuchaaiits Sta. Bui. 92, pp. 36). — A report of analyses of 324 samples of fer-
