2. Notes on Wood Ashes. 



This subject has engaged our attention for past seasons 

 and has been discussed at length in previous reports. 



During the past year (1899) 24.4 per cent, of the mate- 

 rials sent on for analysis consisted of wood ashes, as against 

 40.1 per cent, the previous year (1898). 



The wood ashes sold for manurial purposes in our State 

 are subject to official inspection, and the dealers in this com- 

 modity must secure a license to sell before they can legally 

 advertise their article. The goods must be sold on a guar- 

 anteed analysis, stating their percentages of potash and of 

 phosphoric acid present, and this analysis must be fastened 

 to each package or car that contains them. As the dealer is 

 obliged only to guarantee the amount of potash and of phos- 

 phoric acid present in the ashes, no objection can be raised 

 regarding the amount of moisture, so long as the specified 

 amount of those two elements is present. Wood ashes
