BOARD OF AGRICULTURE. 



Some reduction in prices is to bo expected for the coming 

 season, on account of a decided decline in some of the lead- 

 inor articles of the crude stock of fertilizers. A statement of 

 the late wholesale prices in the Boston and New York mark- 

 ets accompanies these pages. An addition of twenty per 

 cent, to the wholesale price approximates the customary 

 retail charges. A late attempt to introduce ground 

 leather refuse as a nitrogen source into ammoniated super- 

 phosphates deserves the serious attention of the Board. 

 Whilst it remains very desirable that all suitable nitrogen- 

 containing refuse material from our various industries should 

 be economized for manurial purposes, it remains not less 

 justifiable to restrict manufacturers in the use of articles of 

 doubtful merits without ffivino; due notice of the fact.
