This sample of fresh hen manure came from the same party 

 who sent on the dry sample. It was inferior iii quality as 

 compared with the first material ; it contained for the same 

 amount of organic matter about twice as much worthless earthy 

 matter. In a dry state, corresponding with the first sample, 8 

 per cent, of moisture, it would be worth only one-half as much, 

 i. e., about $5 per.ton. 



Ashes of Chestmit Railroad Ties.

Insoluble mineral matter, 77.83 



The material was of a dark brown color, and evidently not 

 the pure ash, for it contained 77.83 per cent, of worthless 

 earthy matter. The ash in the above-described state does not 

 pay carrying any considerable distance ; it is worth much less 

 than leached ashes.

This ash, from a waste product of a tannery, has lost a large 

 percentage of its original potash.
