The guardian of an heir’s land is to take reasonable issues, customs and services, without destruction and waste of his men and goods, and if the guardian of the land inflicts destruction and waste, he is to lose the wardship. And the guardian is to maintain buildings, parks, fishponds, pools, mills and other things pertaining to that land, out of the issues of the same. And heirs are to be so married that they are not disparaged, and this by the counsel of their near kinsmen.
