(Little Poud at South Braiutree.) 



Sent on by A. Drew, Esq., Boston, Mass. 



Analysis of a fairly dried samples : 



The material in its natural state contains 72 per cent, water ; in its 

 composition it resembles a fibrous peat ; yet it is less humified, and 

 will yield its nitrogen, etc., more readily. One ton of the analyzed 

 material represents a commercial value of from 5 to 6 dollars.
