In 36 samples of cotton-hull ashes the highest percentage of water- 

 soluble potash found was 30.94, the lowest 11.1, and the average 22.62. 

 ""Allowing 4i, 1, and 2 cts. per pound, respective!}', for water-soluble, 

 citrate-soluble, and insoluble phosphoric acid, the water-soluble pot- 

 ash cost from 4.2 cts. to 7.3 cts. per pound, or 6.7 cts. per pound on the 

 average — a little less than in the previous j-ear (7.1)." 



The total and water-soluble potash were determined in 7 samples of 

 cotton-hull ashes, with the following results: 



Water-soluble and total j)Otasli in cotton-hull ashes. 



Eleven samples of unleached ashes and 1 sample of leached ashes 

 were examined. The unleached ashes included 8 samples of '' Canada 

 ashes " in which the average per cent of water-soluble potash was 4.63, 

 of phosphoric acid 1.54, and lime 33.57.

Commercial fertilizers, 'SI. A. Scovell, A. M. Peter, and H. E. Curtis {Kentucky 

 Sta. Bui. 8.5, jip. 79-129).— A brief account is given of the inspection of fertilizers in 

 Kentucky during the year 1899, with a list of fertilizer dealers complying with the 

 law, and analyses and valuations of 406 samples of fertilizers. 



"The results of the analyses show that of the 406 samples analyzed, 94, represent- 

 ing 56 brands and 24 firms, fell so far below the guaranteed analyses of the manu- 

 facturers in phosphoric acid, nitrogen, or potash, or any two or all three of these 

 constituents, as to be unaeeounted for ))y variations in sampling or analysis."
