Complete passage: The farmer is up before dawn on shearing-day, driving his flock into pens. By eight o'clock the shearers arrive and, after a hearty breakfast, they take their places on long benches that the farmer has improvised in the pens. Shears are taken from leather cases and sharpened with whetstones; a fire is lighted to heat pitch for the marking; and the work begins. Soon the shearers fall into their routine. A lad seizes a sheep from the pen and ties its feet-not with a cord, because that might injure it, but with a strip of sacking. The sheep is carried to the benches, and the shearer begins to slice off the wool. First he shears the coarse wool from the sheep's belly, then lays the animal on its side on the bench between his legs while he snips at the curly wool round the neck. He works to and fro along the ribs, peeling the wool back until it hangs like a cloak doubled back over the animal. Then he turns the sheep over and begins on the unclipped side. In a few moments the whole fleece falls away in one piece, looking like a dirty grey rug. A few more snips from the shears and the wool is cut from either side of the sheep's tail, leaving the animal white and naked. The shearer pushes the sheep to the ground and immediately calls for another animal. Meanwhile the lad daubs the farmer's mark in pitch on the newly shorn sheep, unties her legs, and drives her out of the shearing pens. A second lad-the farmer's son-seizes the fleece as it is tossed aside, rolls it up, tucking the tail-wool in first, and secures the bundle by knotting the neck. Any loose clippings are gathered separately. The work continues till one o'clock, when the farmer's wife summons the men to dinner. Each man finishes the sheep that is beside him, then the whole party goes back to the farm house. The men troop into the farm kitchen, leaving their dogs to scuffle in the yard. After the shortest of dinner-breaks-for there is much to be done-the shearing continues, and the pile of fleeces mounts. Question: 'The sheep is carried to the benches.' It is an example of
