MULTURE 133 tween the monks of St Albans and their tenants (graphically retold in Froude's Short Studies, "Annals of an English Abbey "), when the Abbot had successfully carried off the hand-mills, he used the stones from them to pave the floor of his private parlour.1 The lord took his profit in kind from all those coming to the mills. Every one had to contribute a certain proportion of his grain which was known as "multure". No clear figure can be given to express this proportion: it varied very considerably, and the Statuta Pistorum* (thirteenth century) assessed it at the twentieth or twenty-fourth part of the grain, but the details given in accounts and other documents show it to have averaged some- thing more like a sixteenth part.3 Now it must be remembered that the price of corn varied very considerably during these cen- turies, so that the value of this multure also varied very con- siderably. The serf, therefore, was not charged a fixed price for the mill's service, but found himself forced to yield up something considerably more precious in times of shortage than after a good harvest. Hence, no doubt, many of the charges of extortion so commonly levelled against the miller. Added to this was the galling knowledge that the lord paid no multure, neither did the parish priest, despite their comparative wealth.4 Then again, the amount of multure taken varied as between free men and serfs: on Durham manors we find the free paying only one twenty- fourth, while the serf gave one thirteenth5—all incidents em- phasising the differences between class and class, and inevitably leading to friction and bad blood. The mill standing by the river bank was fed by water diverted along a watercourse and into a mill-pond. This was banked up with clay and turves, and the water was regulated by flood gates, and by sluices which allowed the miller to control his head of water. A very full account of the structure of the medieval Welsh mill may well serve to describe the innumerable water- mills throughout England at this period. 1 Gesta Abbatum (R.S.), i, 4ioff; n, i4Qff. 2 Statutes of the Realm, I, 203-3. 3 Ouisborough Cart.
