the system of construction is very similar, but pre- 

 cautions have been taken which are of a considerable 

 importance. In the first place on each side we have a 

 gutter to carry off the water that has fallen from the 

 roof of silo. In the above case the water frequently 

 filters throngh and gains the mass by the lower portion. 

 The plan of ventilation consists in having at the bottom 

 a certain number of sticks ; perpendicular to these, 

 others are placed, which enable the gases to make their 

 escape between the same. But there is no possibility 

 of renewing the air. A precaution taken here, worthy 

 of notice, is to have a gutter at the bottom where the 

 water resulting from the evaporation can collect. 



In Saxony we are told that their silos hold several 

 hundred tons of beets. (See fig. 58.) These, as can be

 be costly to the farmer; it consists in the digging of 

 two ditches, the lengths of which are variable, two feet
