Quotation from: The Beginner's American HistoryWritten by: D.H. Montgomery |

He said to himself, If I fasten some upright pieces of wire in a board, and have the wires set very close together, like the teeth of a comb, and then pull the cotton wool through the wires with my fingers, the seeds, being too large to come through, will be torn off and left behind. He tried it, and found that the cotton wool came through without any seeds on it. Now, said he, if I should make a wheel, and cover it with short steel teeth, shaped like hooks, those teeth would pull the cotton wool through the wires better than my fingers do, and very much faster.
