HISTORY OF THE AMERICAN MENHADEN. 497 



In Peruvian guanos tbo same rates are adopted as for the superphos- 

 phates, the additional ingredient potash being rated at 8. 



The prices are those at which the articles have been sold, or offered 

 to farmers during the year at the pkices of sale ; the lower rates in 

 large quantities, lots of a ton or more, for cash ; the higher one for 

 smaller lots, or on time. 



In addition to the analyses and valuations given in the text of the 

 report, the following are presented as indications of the actual condi- 

 tion of the fertilizer market in respect to three most important classes 

 of commercial fertilizers — nitrogenous superphosphates, Peruvian gua- 

 nos, and fish manures. The prices given are those which prevailed in 

 1875-76, and are in some cases a trifle higher than now rule.
