The silo, which is the Gurler type, was then started and carried up with the barn. It was built by placing 2 × 4 studs around the circle, one foot on centers, and ceiling inside with 12 × 6-inch lumber. This 12-inch lumber was obtained by re-sawing 1 × 6 yellow pine fencing. Common lath were then put on horizontally in the regular way inside, without furring out, and plastered with rich cement plaster.

The sill of the barn is 6 × 6, made up of 1 × 6s, and built on top of the wall. Building it up in this manner makes a stronger sill than can be obtained in any other way, as it forms a continuous hoop around the barn.

The joists are 2 × 12s notched 6 inches to fit the sill, so that the outer ends rest on both the sill and the brick wall. The outer span of joists is 14 feet and the inner ends of these joists rest on a similar sill built of 1 × 6s on top of the 4 × 4 supports at the stanchions. The inner span of joists, between the stanchions and the silo, is 8 feet, the outer end resting on the sill over the stanchions, and the inner end on a 112 × 6-inch band, made up of three 12 × 6-inch pieces, running around the outside of the silo. These joists are placed 212 feet apart at the outside of the barn, and half as many joists are used in the inner span, making the joists at the silo one foot apart. The number of joists under the driveways are doubled, being only 1 foot and 3 inches apart at the outside of the barn.

The studs, which are 2 × 6s, 20 feet long, were then placed on the sill, about 2 feet 6 inches apart, being as evenly spaced between the windows as possible, and temporarily braced, as shown in [Fig. 13], until the 8-inch ship lap ceiling could be nailed on the outside. This was carried up 5 feet to the second scaffold, and then covered to this height with shingles laid 5 inches to the weather. The scaffolding was then moved up and this process repeated until the siding was completed. The plate, made up of five 1 × 4s, was then built in the notch in the top of the studs shown in [Fig. 13].
