The same law also required that the miller’s “toll-fat” (or dish) and “sceppum” (or scoop) used to measure grain be accurate. The manorial seal on a measure testified that it had been compared with the standard measure and found exact. But millers in all lands and times (the present excepted, of course) have been adept at finding ways to outwit law and customer at the same time. A method popular among some millers was to build square housings for the millstones, thus providing four innocent corners in which quite a bit of meal could collect. The more artful members of the craft built a concealed spout that carried a small proportion of the meal to a private bin while the visible spout delivered the bulk of it to the customer’s container. Other stratagems, too varied and too numerous to list here, testify to the craftiness of many millers. The lengths to which the law went in trying to keep up can be seen in an English statute of 1648. This law, closing one loophole through which a miller could levy a hidden toll, allowed him to keep no hogs, ducks, or geese in the neighborhood of the mill, and no more than three hens and a cock. All of this ingenuity, most of the popular suspicions of the milling craft, and some of the legal restrictions consequent upon both, crossed the Atlantic along with the millers and millwrights who came to the colonies. More details of this in a moment; meantime, what of the mill that belonged to the man that owned the name of rascal? [Illustration: _Some simple grist mills: (A) stone mortar and pestle; (B) saddlestone and metate; (C) sappling-and-stump type of mortar and pestle, often used by early colonists; (D) Roman quern._] _THE OLD MILL STREAM OF HISTORY_ For uncounted generations in every pre-mechanical civilization grain has been ground in a variety of one-woman-power devices. Pounding with mortar and pestle was one of the earliest and is still the crudest of these devices. The saddlestone-metate device, still to be seen in some areas of Central and South America, substituted a rolling, sliding motion to the upper stone that rubbed and sheared the grain. Finally, the Roman quern, rotating continually in the same direction and shearing the kernels between grooved faces of matched stones, opened the door to the use of natural instead of muscle power. History does not record the name of the man, probably a Greek, who first harnessed natural power to grind grain between opposing stones. Possibly it happened when his wife handed him the family quern with the command, “Here, you do it!”—in Greek, of course. What he did, instead of earning his bread by the sweat of his brow, was to apply brain power. He fixed a water wheel to the lower end of a vertical shaft and attached the upper end to the upper stone of his handmill. And then, no doubt, he went fishing in the millstream while the flowing water did his work.
