The modern corn crib should be planned and constructed with the conveniences to conserve labor. Handling corn in ear or shelled will be no more the burden of the farm if properly planned.

In the construction of this building you can locate, stake, find grade, level and square the building as described and illustrated in this book and with the rules for the use of the square, you can make any cut. (See rules covering same.) The dimensions of the crib is 28'x40'. The walls are 8" thick and 12" above the driveway floor. Concave the top of the wall to anchor the floor slab. The footings and wall to extend in the ground 18", and at both ends of the driveway put footings 18" deep to prevent rats from burrowing under the floors. (See fig. 54.) The floor slab for the cribs are 6" thick, crowned in the center 2" and extend over the wall 1" for drip. Place iron sockets in the concrete slab, when poured, 2' on center lined and leveled for the support of the studdings. The cement floor for the driveway is 5" thick and should be mixed. Five shovels of sand to 1 shovel of cement for solid floor. The dimension lumber for building, outside studs, 2"x6"xl4'. Inside studs 2"x8"xl4', double plate, with same dimension; 2"x8" ties under the plates every 4'. Nailed to the studs and plates. Cross joists for bin 2"x8" every 2', ties under bin

2"x8" every 2'. Ties and cross ties in crib l"x8". The studs above the inside plates 2"x6". Perline plates 2"x6". Rafters 2"x6". 16' bin at both ends, leaving 8' opening above between the bins in center for elevator. Board the bottom and side of the bin with matched flooring. Sheet and shingle (see rule for same). Use bats and drop siding for the outside wall. Matched flooring for doors. Board off a space 6' wide the width of crib and 7' high for engine room. Put slides along the length of the crib to let the corn out for shelling. Set sheller by the elevator, to elevate the corn to the bins from the sheller. Begin in the fore part of this book and demonstrate every rule and diagram. This will enable you to make any cut required for this building. (Fig. 54.)
