In 1900, with the cotton seed meal ration, the average 

 amount of excrement, free from sawdust, dropped per 

 cow in 24 hours was 59.4 pounds; tlie average amount 

 collected durinj: tlie 10 hours of 8tal)lin<r was onlv 30.2 

 piMinds. 



Apparently about one-half the manure was dropped 

 in the barn and about one-half in the lots. 



This statement is important because the manure 

 droi)ped on the lots or pastures usually suffers greater 

 losses, and hence is worth less than that collected while 

 the cows are in the stable. However, the high value 

 of manure from grain fed cows should prompt every 

 dairyman to gather and protect the manure from the 

 lot as well as that from the barn. 



In conclusion let us note that the manure from the 

 cotton seed meal ration was greater in amount and much 

 richer in nitrogen than that from the cotton seed ration. 

 Taking the average amounts of manure in all cases 

 where the co^^ s were confined for the whole dav and 

 using the analysis of the samples collected in the last 

 periof of 28 days in 1901, we find that the daily excre- 

 tion of liquid and solid excrement (including bedding) 

 contained plant food as follows: 



Lbs. 

 nitrogen. 



60.9 lbs. manure from cotton seed ration 306 



84.2 lbs. manure from cotton seed meal ration TOO 



With the cotton seed meal ration the daily output of 

 nitrogen in the manure was more than twice as great, 

 and the amounts of phosphoric acid and potash consid- 

 erabh' larger than with the ration made up largely of 

 cotton seed.
