Water mills used for grinding corn are said to have been invented by Belisarius, the General of Justinian while besieged in Rome by the Goths, 555. The ancients parched their corn and ground it in mortars. Afterwards mills were invented which were turned by men and beasts with great labour, yet Pliny mentioned wheels turned by water. _See Telo-dynamic Transmitter._ The simplest mill for bruising grain was nothing more than two stones between which it was broken. Such was often seen in the country of the Niger by Richard and John Lander on their expedition to Africa. The manna which God gave to the children of Israel in the desert "the people went about and gathered it, and ground it in mills or beat it in a mortar," _Numbers xi._ 8. From mills and mortars thus rudely constructed there must have been obtained at first only a kind of peeled grain which Dr. Eadie says may be compared to the German _graupe_, the English _groats_, and the American _grits_ or _hominy_. Fine flour was laboriously obtained from household mills like our coffee mills. The oldest mention of flour is in Gen. xviii. 6; but bread which is made of flour or meal is named in Gen. iii. 19. In order to reduce the flour to a proper degree of fineness it was necessary sometimes to have it ground over again and cleared by a sieve. Samson when a prisoner to the Philistines was condemned to the mill-stone to grind with his hand in the prison-house, Judges xvi. 21. In England prisoners are sent to the treadmill as a punishment. The Talmudists have a story that the Chaldeans made the young men of the captivity carry mill-stones with them to Babylon where there seems to have been a scarcity at that time. They have also a proverbial expression of a man with a mill-stone about his neck which they use to express a man under the severest weight of affliction. Windmills are of great antiquity and stated to be of Roman or Saracen invention, they are said to have been originally introduced into Europe by the Knights of St. John, who took the hint from what they had seen in the crusades (_Baker_). Windmills were first known in Spain, France and Germany in 1299 (_Anderson_). Wind saw-mills were invented by a Dutchman in 1633, when one was erected near the Strand in London. Acorns was the coarse fare of the old inhabitants of Britain, when wild Britons painted their skin to make themselves appear more fierce, and native tribes in a still more barbarous condition, half naked or clad in the skins of beasts, not cultivators of the soil, subsisted on the flesh of their cattle or on the precarious produce of the chase. Packs of hungry, growling, cruel wolves[1] prowled in the woods and forests, and Druidical Priests exercised an entire control over the unlettered people they governed, and human captives seized on Britannia's shores were offered as victims in sacrifice, a holocaust to the divinities and false gods which ancient Britons worshipped!
