the; pre;si;rvation of he:n manure. 201 



Without anything being added. 



Mixed with 2^ pounds kainit. 



Mixed with 40 pounds plaster. 



Mixed with 24 pounds acid phosphate. 



Mixed with 15 pounds kiln dried pine sawdust. 



Mixed with 15 pounds sawdust and 54 lbs. kainit. 



Mixed with 15 pounds sawdust and 82 lbs. plaster. 



Mixed with 15 pounds sawdust and 47 lbs. acid phosphate. 



These lots were put in barrels and stored in a room in one of 

 the barns from May, 1903, to November, 1903. They were 

 weighed and sampled in November. The following notes on 

 the mechanical condition were taken at the time of sampling. 



Hen manure alone. Mouldy. Ammonia very distinctly com- 

 ing off. Not very lumpy and broke up pretty easily. 



Hen manure and sawdust. About the same as hen manure 

 alone, except a little drier, and broke up a little more readily. 



With kainit alone. Quite moist, somewhat sticky. Much 

 like green dung in its mechanical condition. 



With kainit and sawdust. Quite good mechanical condition. 



With plaster. Quite dry, but lumpy. 



With plaster and sawdust. Dry and hard lumps of plaster. 



With acid phosphate. Rather wet and sticky. 



With acid phosphate and sawdust. Quite good mechanical 

 condition, resembling that mixed with kainit and sawdust. 



The addition of the sawdust improved very decidedly the 

 mechanical condition of the dung, particularly in the lots to 

 which acid phosphate and kainit were added. The tendency of 

 the plaster to lump was not much less with the sawdust than 

 without. None of these lots could be readily fined so as to be 

 used in a fertilizer drill, but any of them, and particularly the 

 lots treated with sawdust and acid phosphate or kainit could 

 be well applied with a machine similar to the Kemp manure 

 spreader. 



The results of the analyses are given in the table which 

 follows.
