 unite with the alkaline matter, the soda or 

 potash of the burnt vegetable ashes, to form 

 nitrate of potash or soda : the hydrogen, the 

 other constitutent of ammonia, being given 

 off. 



After what has already been said about the 

 utility of these salts as fertilizers, it will be 

 needless to add more here, than earnestly to 

 recommend every agriculturist to adopt these 

 simple means for the production of two ma- 

 nures, which in value to the farmer cannot be 

 surpassed — both for the facility and economy 

 with which they may be prepared, and which 

 would by their fertilizing properties confer a 

 benefit not only on the farmer, but on the com- 

 munity at large. 



It may be urged as an objection, that in 

 many localities, far distant from towns and 

 cities, that this manure could not be obtained 

 in suflJcient quantities to supply the place 

 of other substances more readily obtained. To 

 this objection we would beg to suggest, that 

 if ever a demand for this article exists, means 

 will be taken to secure a supply ; and, that in 

 such a case as above supposed, the fanrer's 

 wagon would be enabled to load back from 

 the towns or market where their produce must 

 eventually be consumed, with this matter. 

 And farther, they may commence with the 

 supply that is always to be had to some ex- 

 tent on their own farms, and thus verify the 

 results here predicted. 



We will only add, that the urine of one 

 man, taken at its lowest calculation, will pro-
