The prevalence in ancient Russia of the same rude and elementary mode of farming is established by numerous charters and contracts, some of which are as late as the end of the seventeenth century, whilst others go back to the beginning of the sixteenth. It would appear that previous to that date such contracts were not put into writing, apparently on account of the small diffusion of knowledge. We are therefore reduced to the necessity of presuming the existence of these contracts solely because the intrinsic causes which brought them into existence in the sixteenth century had been in operation for hundreds of years before. The peasant, on entering into such a contract, took upon himself the obligation of paying back in the course of time the money which had been lent to him -- the "serebro," silver, according to the expression used in contemporary documents. From the name of the capital intrusted to them (the serebro) arose the surname of serebrenik, which may be translated silver-men, under which peasants settled on a manor were generally known; their other being polovnik, or men paying half of their yearly produce to the lord, although as a rule their payments did not amount to more than a quarter. So long as his debt remained unpaid the metayer was obliged to remunerate the landlord by villein service performed on the demesne lands of the manor. According to the German writer Herberstein, who visited Russia in the seventeenth century, the agricultural labour which the serebrenik performed for the lord very often amounted each week to a sixdays' service, at any rate in summer. Contracts still preserved also speak of other obligations of the serebrenik, very like those of the medieval English socman. Such, for instance, were the obligations of cutting wood and of forwarding it on their own carts to the manor-house, and of paying certain dues on the occasion of the marriage of the peasant's daughter. I need not insist on the similarity which this last custom presents to the medieval English and French maritagium, or formariage, so evident is the likeness between them. Custom also required the peasant to make certain presents to his lord at Christmas and Easter, or at some other yearly festival, such for instance as that of the Assumption of the Blessed Virgin.
The peasant who chose to settle on the land of a manorial lord got the grant of a homestead in addition to that of land, and this was the origin of a sort of house-rent called the projivnoe, which as a rule amounted yearly to the fourth part of the value of the homestead.
As to the land ceded by the landlord to the settler who wished to live on his manor, its use became the origin of another special payment, the obrok, which represented a definite amount of agricultural produce. The obrok was often replied by the obligation of doing certain fixed agricultural labour on the demesne land of the manor.
As soon as the peasant had repaid the money borrowed from the manorial lord, and had discharged all the payments required from him for the use of his land and homestead, he was authorised by custom to remove wherever he liked, of course giving up to the squire his house and his share in the open fields of the manor.
At first this right of removal could be exercised at any period of the year, but this being found prejudicial to the agricultural interests of the country certain fixed periods were soon established, at which alone such a removal was allowed. Usually the end of harvest was fixed as the time when new arrangements could be entered into with regard to future agricultural labour without causing any loss to the interests of the landlord. Not only in autumn, however, but also in spring, soon after Easter, manorial lords were in the habit of permitting the establishment of new settlers on their estates, and the withdrawal of those peasants who expressed a desire to leave.
The first Soudebnik, the legal code published by Ivan III in 1497, speaks of the festival of Saint George, which according to the Russian calendar falls on the 26th of November, as a period at which all removals ought to take place. Those peasants who had not been fortunate enough to free themselves from all obligations to the manor by this period were obliged to remain another year on its lands. He who, was unable to repay the lord the sum borrowed was reduced to the same condition as that of the insolvent farmers of the Roman ager publicus, who, according to Fustel de Coulanges, saw their arrears of debt changed into a perpetual rent called the canon, and their liberty of migration superseded by a state of continual bondage to the land they cultivated. No Russian historian has shown the analogy existing between the origin of the Roman colonatus and that of Russian serfdom so clearly as Mr Kluchevsky, the eminent professor of Russian history in the University of Moscow. It is to him that we are indebted for the discovery of the fact that centuries before the legal and general abolition of the right of free migration a considerable number of peasants had thus ceased to enjoy that liberty. Such was the case of those so-called "silver-men from the oldest times," viz., starinnii serebrenniki, who during the sixteenth century were already deprived of the right of free removal from no other cause but the want of money, so that the only condition on which they could withdraw from the manor on which they were was that of finding some other landlord willing to pay the money they owed, and thereby acquiring the right to remove them to his own manor.
