Survey your lands and tenements by true and sworn men. First survey your courts, gardens, dove-houses, curtilages, what they are worth yearly beyond the valuation; and then how many acres are in the demesne, and how much is in each cultura, and what they should be worth yearly; and how many acres of pasture, and what they are worth yearly; and all other several pastures, and what they are worth yearly; and wood, what you can sell without loss and destruction, and what it is worth yearly beyond the return; and free tenants, how much each holds and by what service; and customary tenants, how much each holds and by what services, and let customs be put in money. And of all other definite things put what they are worth yearly. And by the surveyors inquire with how much of each sort of corn you can sow an acre of land, and how much cattle you can have on each manor. By the extent you should be able to know how much your lands are worth yearly, by which you can order your living, as I have said before. Further, if your bailiffs or provosts say in their account that so many quarters have been sown on so many acres, go to the extent, and perhaps you shall find fewer acres than they have told you and more quarters sown than was necessary. For you have at the end of the extent the quantity of each kind of corn with which one shall sow an acre of land. Further, if it is necessary to put out more money or less for plows, you shall be confirmed by the extent. How? I will tell you. If your lands are divided in three, one part for winter seed, the other part for spring seed, and the third part fallow, then is a plowland nine score acres. And if your lands are divided in two, as in many places, the one half sown with winter seed and spring seed, the other half fallow, then shall a plowland be eight score acres. Go to the extent and see how many acres you have in the demesne, and there you should be confirmed.
