The cens et rentes made up the only payment which the seigneur received each year, but there was another which became due at intervals. This was the payment known as the lods et ventes, a mutation fine which the seigneur had the right to demand whenever a farm changed hands by sale or by descent, except to direct heirs. One-twelfth of the value was the seigneur's share, but it was his custom to rebate one-third of this amount. Lands changed hands rather infrequently, and in any case the seigneur's fine was very small. From this source he received but little revenue and it came irregularly. Only in the days after the conquest, when land rose in value and transfers became more frequent, could the lods et ventes be counted among real sources of seigneurial income. Then there were the so-termed banalites. In France their name was legion; no one but a seigneur could own a grist-mill, wine-press, slaughter-house, or even a dovecot. The peasant, when he wanted his grain made into flour or his grapes made into wine, was required to use his seigneur's mill, or press, and to pay the toll demanded. This toll was often exorbitant and the service poor. In Canada, however, there was only one droit de banalite--the grist-mill right. The Canadian seigneur had the exclusive milling privilege; his habitants were bound by their title-deed to bring their grist to his mill, and his legal toll was one-fourteenth of their grain. This obligation did not bear heavily on the people of the seigneuries; most of the complaints concerning it came rather from the seigneurs, who claimed that the toll was too small and did not suffice, in the average seigneury, to pay the wages of the miller. Many seigneurs declined to build mills until the royal authorities stepped in with a decree commanding that those who did not do so should lose their banal right for all time. Then they bestirred themselves.
