Silos and Silage in Colorado.

only difference between this and the pit silo would be that a con¬ 
tinuous door and chute are built which connect with the barn below. 
The freezing is overcome and the necessary equipment for filling is 
less expensive because elevating is not necessary. The cut shows 
a bank silo on the farm of Mrs. Ed Dwyre of Monument, Colo. 
This silo has now been filled three years with uncut corn. The 
corn is short, and a sample taken from the silo this spring was a 
perfect specimen of good silage. The silo is 16x24 feet with a 
6-inch wall. This silo should give splendid results for an indefinite 
period of years. This silo, with a rated capacity of ninety tons, 
cost $263.05, the cost being divided into the following items: 
Cost of forms.$ 21.36 
Cost of material... 120.39 
Cost of labor. 121.30 
$263.05

These figures include the cost of material for roofing, but not 
the cost of labor for roofing. The cost per ton capacity with this 
silo would therefore be approximately $3.00. 
Trench Silo .—A trench can be easily built in a side hill or 
even on level ground very cheaply, with a team and slip-scraper. 
The walls should be trimmed smooth. Any sized trench can be 
dug. This trench filled with green forage and well packed, covered 
over with a foot of straw, and weighted down with about two feet 
of dirt, should give good results. The German method of siloing 
beet leaves and tops in alternate layers of five to six inches with 
straw in a trench silo built in this way, is a practice which could be 
very economically adopted by Colorado farmers for the preserva¬ 
tion of their tops and leaves as well as forage crops.
