ing the pit may be made with sloping sides, smallest at the 

 bottom. 



In using such a silo, especially when filling it, care should 

 be observed in going into it when there is a possibility that 

 carbonic acid has accumulated to a dangerous extent. There 

 need be no danger in using such a silo if caution is observed 

 as stated on page 427. 



525. Weight of Silage per Cubic Foot The weight of 

 corn silage increases with the depth below the surface, with 

 the amount of water in the silage, and with the diameter of 

 the dlo. In silos of small diameters the amount of surface 

 in the wall is so much greater in proportion to the silage 

 contained that the friction on the sides has more influence 

 in preventing the settling of the silage. In the following 

 table will be found the weights of silage per cubic foot in 

 round silos given for different depths and the mean weight 

 of silage above the given depth : 



Table showing the computed weight of well matured corn sil* 

 age at different distances below the surface, and the com- 

 puted mean weight for silos of different depths, two days 

 after filling. 



526. Capacity of Silos The amount of silage which may 

 be stored in a silo increases in a higher ratio than the depth
