Of the 247 brands analyzed 32 were accompanied by guaranties of 

 definite amounts of eacli of tlie fertilizing- constituents, wbile in case 

 of 215 brands the inaxinium and minimum amounts were guaranteed. 



"In the 32 samples in wMcli a definite amount of each constituent was guaranteed 

 the average quantity guaranteed and found was as follows:

" Or an excess of 13.9 per cent of nitrogen, of 9.4 of available phosphoric acid, and 

 of 6.7 of iiotash over the guaranteed amonnt. . . .

Fertilizer inspection and analysis in Vermont, J. L. Hills and 

 B. O. White {Vermont Sta.BiU.41, pp.16). — This includes the sched- 

 ule of trade values of fertilizing ingredients for 1893 and 1894; notes on 

 valuation; tabulated analyses and valuations of 79 samples of fertiliz- 

 ing materials, including various factory-mixed fertilizers, wood ashes, 

 muck, and tankage; a comparison of the values of fertilizers licensed 

 in 1893 and 1894, and a review of 10 years of fertilizer insi^ection in 

 Vermont. 



" The comparison of the average composition of the fertilizers sold in the State this 

 year with those of the past 10 years shows that the 1894 goods are of poorer quality 

 than any sold during this time. The average selling price is lower than ever before, 

 being 85 cts. less than last year, but the average valuation is $1.62 less than in 1893, 

 based on the same (1894) trade values. . 



" Since 1885 over 90 different brands of fertilizers have been sold in Vermont. Sell- 

 ing prices have dropped 17 per cent and valuations 20. The percentage of cost over 

 valuation was least in 1889 and is most now. Owing to the lower prices of nitro-
