'Item--Ut unicuique æcclesiæ vel una mausa integra absque alio servitio adtribuatur, et presbiteri in eis constituti non de decimis, neque de oblationibus fidelium, nec de domibus, neque de atriis vel ortis juxta æcclesiam positis, neque de præscripta mansa, aliquod servitium faciant præter æcclesiasticum; et si aliquid amplius habuerint, inde senioribus suis secundum patriæ morem, debitum servitium impendant.'

(_Venedotian Code._) XXIV. _Of Co-tillage this treats._ 1. Whoever shall engage in co-tillage with another, it is right for them to give surety for performance, and mutually join hands; and, after they have done that, to keep it until the tye be completed: the tye is twelve erws. 2. The measure of the erw, has it not been before set forth? 3. The first erw belongs to the ploughman; the second to the irons; the third to the exterior sod ox; the fourth to the exterior sward ox, lest the yoke should be broken; and the fifth to the driver: and so the erws are appropriated, from best to best, to the oxen, thence onward, unless the yoke be stopped between them, unto the last; and after that the plough erw, which is called the plough-bote cyvar; and that once in the year * * * * * 10. Every one is to bring his requisites to the ploughing, whether ox, or irons, or other things pertaining to him; and after everything is brought to them, the ploughman and the driver are to keep the whole safely, and use them as well as they would their own. The driver is to yoke in the oxen carefully, so that they be not too tight, nor too loose; and drive them so as not to break their hearts: and if damage happen to them on that occasion, he is to make it good; or else swear that he used them not worse than his own.
