BULLETIN No. 143 



[February, 



Siding, 8-inch drop siding, put on horizontally, nailed with iod 

 nails. Ends holding well. 



\Yindows, 12 light, 10x12 glass; one window every six feet. 

 This gives an abundance of light in the center of the barn. 



Doors, built on circle; (not satisfactory). 



Silo, round ; diameter, 24 feet over all ; height, 53 feet, ex- 

 clusive of 12-foot space for water tank on top; capacity, 500 tons. 



FIG. 32. INTERIOR OF BARN NO. 4, SHOWING STAINS AND FEED AU,EY. 



Studs of silo, jx4s placed 12 inches on center. Ceiled inside of 

 studs with two thicknesses of half-inch lumber with paper between. 



Remarks : Considering its size, the construction of this barn is 

 apparently too light to be substantial, as the joists and studs are 

 too small and too far apart, yet it has stood for nine years with 

 no more evidence of wear than is common with any barn. 



\Yere the owner to build again he would place the studs only 

 2% feet apart and use 2x12 joists, 2 l / 2 feet apart at the outside 

 wall. He would also use cement plaster on inside of silo.
