"A flail," said Mr. Blake, "is what the farmers used to use before threshing machines were invented. And I had Mr. Henderson bring this one from his farm to thresh out your beans, Mab, as we haven't enough to need a machine, even if we could get one."
"What does thresh mean?" asked Hal.
"It means to beat, or pound out," his father explained. "You see wheat, oats, barley, rye and other grains, when they grow on the stalks in the field, are shut up in a sort of envelope, or husk, just as a letter is sealed in an envelope. To get out the letter we have to tear or break the envelope. To get at the good part of grain—the part that is good to eat—we have to break the outer husk. It is the same way with peas or beans.
"When they are green we break the pods by hand and get out the peas or beans, but when they are dried it is easier to put a pile of pods on a wooden floor and beat them with a stick. This breaks the envelopes, or pods and the dried peas or beans rattle out. They fall to the bottom, and when the husks and vines are lifted off, and the dirt sifted out, there are our beans or peas, ready to eat after being cooked.
"The stick with which the beating is done is called a flail. One part is the handle, and the other part, which is fastened to the handle by a leather string, is called a swingle, or swiple, because it swings through the air, and beats down on the bean or pea pods.
"In the olden days wheat, rye and oats were threshed this way on a barn floor, and in the Bible you may read how sometimes oxen were driven around on the piles of grain on the threshing floor, so that they might tread out the good kernels from the husks, or envelopes that are not good to eat. But I'll tell you more about that when we get on the farm."
"When are we going to beat out my beans?" asked Mab.
"In a week or so, as soon as they get dried well, and are ripe enough so that they are hard, we will flail, or thresh them," answered Daddy Blake. "I am going to thresh some peas, too, to have them dried for this Winter."
Farmer Henderson left the flail which he had made for Daddy Blake, and Hal and Mab looked at it. They could whirl it around their heads, but their father told them to be careful not to hurt one another.
"I'm going to thresh some peas!" cried Hal.
