One hundred parts of wool contained washings 



The amount of potash removed from the wool by mere 

 washing is quite large, and imparts to the resulting solution 

 a considerable value for fertilizing purposes. To utilize the 

 water used for the washing of raw wool for the irrigation of 

 meadow land, etc., when practicable, deserves some trial.

I. The source of this ash is not stated ; it is apparently 

 a mixture of coal ashes and wood ashes ; its agricultural 

 value is but one-half that of a good quality of wood ashes. 



II. This material is of a similar quality as No. I. ; the 

 depreciation in commercial value was, in this case, mainly 

 due to the presence of a comparatively large amount of coal.
