The result of many investigations of the mixed matters above 

 detailed, prove them to contain in every hundred pounds rather le?s 

 than half a pound of nitrogen and about two pounds of phosphoric 

 acid. 



The collection, absorption, and association of the liquid with the 

 solid matters, being the most important factor in the manufacture of 

 an efficient product, it is in all cases advisable to use abundant 

 quantities of cereal straws for littering or bedding, in preference to 

 any other material; they having been found to possess the greatest 

 possible capacity for holding moisture, as indicated by the following 

 figures :
