KNSILAGE AND TEMPORARY SILOS. 85 
The silo we have described was of sufficient capacity to 
take as much herbage as could reasonably be cut, carted, 
packed, and finished off during the course of a week upon the 
farm we visited, which was a small one of about 350 acres. 
Should it be desired to make one of these silos upon level 
ground, where the advantage of a sand or gravel sub-soil 
cannot be found, it is necessary to sink cross rows of drain 
pipes a few inches below the surface of the levelled bed, and 
to place over them a quantity of porous soil sufficient to 
exclude all air. It can then be made in the same manner as 
the one we have described. 
That we profited by the visit, is answered by the fact that 
we have had resource to this temporary and inexpensive 
method of ensilage manufacture year after year, to our advan- 
tage and satisfaction.
