horse manure is thrown out in a loose pile from the stable door. 

 The box was allowed to remain in th.is position until Sept. 30th, 

 when the contents were weighed, thoronghly mixed and duplicate 

 samples sent to the chemist for analysis. 



In order to obtain a sample of manure for analysis to compare 

 with that put in the wooden box, the horse manure for a day was 

 collected in the same manner on the succeeding Sunday. These 

 trials were made on Sunday, becanse on that day the horses were 

 in the stable all day, and the whole amount of excrement could 1)e 

 obtained. The amount obtained in the second trial was as follows : 



Total weight, manure and bedding 496. 



Weight of bedding 30. 



Total weight of excrement, solid and liquid 466. 



A V. excreted per horse per day 58-25 



There were but eight horses this time, one being absent, the oth- 

 ers were the same and were fed the same. It is fair to assume 

 that the composition of the manure was the same, it being very 

 nearly the same in quantity. The manure was run through a 

 .straw cutter to cut up the bedding and then thoroughly mixed and 

 duplicate samples sent to the laboratory. 



Incidentally it is interesting to note the amount of solid and 

 liquid excrement voided in twenty-four hours by a horse. The 

 average for the two trials is a little less than fift3'-six and one third 

 pounds. Two of the horses were light driving horses, the re- 

 mainder were grade Percheron farm horses of from 1 200 to 1400 

 pounds weight and were fed liberally on oats and hay. 



The composition of the fresh manure and the manure after being 

 exposed as described for six months is given below :

The losses therefore were threefold ; first, a considerable loss in 

 the total weight ; second, a gain in the percentage of water ; and 

 third, a loss in the percentage of valuable fertilizing elements.
