Dairy farming : being the theory, practice, and methods of dairying dairyfarmingbein00shel Year: 1880 modate a farm nf 1,000 acres, or say 150 feet in diameter. The plates jxirform the office of the bottom choixl, and the liip rafters of the top choi-d, in a truss. The strain on the plates is an endwise pull, and if they are strong enough to stand the strain of the push at the foot of the rafters, the bottom of the roof cannot spread, and the rafters, being properly bridged from the middle to the top, cannot crash, and the whole roof must remain rigldlij in place. Its external form being that of an octagonal cone, each side bears equally upon every other side, and it has great strength without any cross ties or beams, re- quiring no more material or labour than the ordinary roof. ' It will be seen by Fig. iJS that there is a drive-way 15 feet wide through the centre of the prin- cipal storey from north to south. There is a line of ' big beams' on either side of this drive-way, 13 feet high, across which a scaffold may be thrown to enable us to occupy the high space over this floor. The posts being 28 feet high and roof rising ll\ feet, the cupola floor is 50 feet above the drive-way floor below. The space above these ' big beams' is quite clear of any obstruction, and a horse pitching-fork may be run at pleasure to any part. The bay for hay on the left side of this floor is SO feet long and has an area of 2,0.'50 square feet, and is capable of hold- ing, when filled to the roof, 160 tons of hay. This bay, extending along the floor 80 feet, may Ite divided into as many parts as required for different qualities of hay, and each part may be quite con- venient for filling and taking out.
