The tirst three samples are rather below a fair average composition 

 of Canada vvood ash, as far as their percentage of potash is considered. 



Sample V. it is stated, was obtained from a smoke-house and had

MECHANICAL ANALYSIS. 



Sample three, consists evidently of bone and meat, and ought to be 

 classed with tankage. The mechanical condition, in which ground 

 bones are offered for sale in our markets, are steadily improving. 

 The finer they are ground, the sooner they act as plant- food. The 

 current valuation recognizes that fact, as will be seen from the previ- 

 ously stated schedule of cost of bones.
