Valuation per 2,000 lbs., 



This sample of fresh hen manure came from the same party 

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

 compared wdth 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 Avorth only one-half as much, 

 i. e., about $5 per ton.

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.
