\cost, including labor, $147. If the brick had been purchased and 

 the labor of excavating for the foundation and laying the brick 

 charged for, the total cost of the silO' would have been approxi- 

 mately $170 without a roof, or $1.13 per ton. 



The staves were rough white pine, 2x4, 14 and 18 feet 

 long, to make the rec[uired height. Four 4x6 uprights were 

 placed on the foundation in the circle, 90 degrees apart, holes 

 having been bored in them to receive the iron hoops, which had 

 threads cut on the ends. The staves were then set in the circle 

 alternating in length, so as to break joints. As each 2x4 was set 

 up it was fastened to the next one by means of six-inch spikes, 

 which were driven through the 2x4's edgewise. Spiking in this 

 way makes the silo much more rigid and it is not so likely to be 

 racked or blown down when empty. When all the staves were in 

 place the silo was tightened by turning up the nuts at the ends of 

 the iron hoops on either side of the 4x6's. The hoops are much 

 closer together at the bottom than at the top, to give the added 

 strength necessary where the pressure is the greatest. 



Four doors 18 inches wide and two feet high were cut in the 

 side, one above the other, about six feet apart. Outside of these 

 was built a chute to prevent the silage from being blown away 

 when thrown down. 



There are several firms who manufacture stave silos and 

 send them out in any size desired, ready to set up. Many of these 

 are made of durable wood and give good satisfaction. One of 

 these silos is illustrated in Cut 33. 



While it is true that a stave silo may be used to advantage in 

 some cases, yet where a permanent silo is desired either the wood 

 silo plastered with cement, or the grout, or brick structure will 

 undoubtedly prove more satisfactory, both on account of greater 

 permanency and the better preservation of the silage.
