Tlie value of the fertilizing constituents in case of the fine refuse 

 material amounts to $23.68, and in case of the coarse material to 

 $16.19 per ton at stated rates. The coarse sample contains 5.1 

 per cent, of fat, while the finer part contains only 3.49 })er cent.

The material was collected in connection with the washing of vvool. 



It contained, besides a considerable quantity of earthy and vegetable 



matter, a liberal proportion of a combination of |)otash with fatty 



acids, peculiar to raw wool. The nitrogen in different samples of 



wool-waste varies widely, judging from persona! observation (from 5 



to 10 per cent. ) The above sample show? the lowest amounts yet 



noticed in an article sent on under that name.
