30 Farmyard Manure. 



Plenty of litter having been supplied to the animals, the 

 fresh manure appeared to me drier than usual, and as the ex- 

 perimental heap under shed necessarily must lose a good deal 

 of moisture on keeping, I thought it desirable to pour water 

 upon it, just sufficient to make it as moist as fresh dung 

 generally appears. This addition of water, which was not re- 

 peated, explains that the manure under shed contained a little 

 more moisture in February, 1855, than when first put up in 

 November, 1854. 



The following Table exhibits the composition of this manure 

 in its natural state :
