In the West we prefer a bag or sack which is made into a pouch by tying the bag-string to one corner of the bottom. Pliny mentions that it is important for the action of the hand and feet to keep time, to secure an even spread of the seed. It is just so with us. A right-handed man will dip his hand into the bag for seed just as his left foot touches the ground. Some sow with both hands. Under the Romans, the amount of seed t<

ver-seed harvester. Grain-hull′er. A machine for taking the cortex or skin from grain, making hulled wheat, pearl barley, hominy, as the case may he. Known also as a decorticator, debranning-machine, hominy-machine, etc. Grain-huller. Wheat is slightly scalded with steam and then fed between roughened surfaces in motion, or it is rubbed between stones or disks which are set at such a distance apart as not to grind it. In the example, inclined serrated plates are attached to the ca axis as the position of the radial bars changes. The fine flour which passes through the cloth is conducted to a bin; the pollard and bran are conducted to a dressing-machine. The average quantity of wheat ground per week is 20,000 bushels. Wheat can be ground and dressed in fifteen minutes, during which time it passes three times from the top to the bottom of the mill by means of screws and elevators. But few hands are employed, the work of the mill being mostly performed by steam-drive

e hole. Frequently, it has cutting-edges on its cylindrical portion, and acts to dress off irregularities and make a perfectly cylindrical opening. Reaming-bits are used in drilling metal; also in dressing to roundness and enlarging the size of holes bored by rock-drills. See reamer. Ream′ing-i′ron. （Calking.) A blunt chisel used for opening the seams between the planking of a ship preparatory to calking them with oakum. Reap′er. A machine for cutting grain in the field. Wheat and barley were commonly cultivated in ancient Egypt. The former was cut in five months after sowing, the latter in four. The wheat was bearded, and generally cut below the ear, as in the annexed figure. It was cut with a smooth-edged or a toothed sickle. Both are represented in the tombs, and illustrations are given in this work under the caption sickle. The whole series of harvesting and thrashing operations are shown in the accompanying illustration, which is from a tomb at Thebe
