10. Every tenant shall be bound to cultivate his lands in a proper and husbandlike manner, with reference to the best practice of husbandry in the district, and to consume upon his lands the whole straw, hay, and fodder grown thereon, and not to sell or remove any thereof, or any manure made upon the said lands from off the same, even during the last year of his lease; the incoming tenant being, however, bound to pay the outgoing tenant the value of the straw, hay, fodder, or manure left by him on the lands. 11. In all cases, where arable lands are situated on a slope or declivity, and are laboured by spade, the tenant shall, when labouring, delve the riggs lengthwise, or along the side of the rigg, each feal or fur extending from the top to the bottom of the rigg, and the delving to begin one season at the right side, and the next season at the left side of the rigg; and, in situations where it is necessary to delve down hill, the tenant shall remove the first or lower feal or fur at the bottom of each rigg, and along the whole breadth thereof, and shall, when the rigg is completely delved, carry the said removed feel or fur to the top, and deposit it in the last fur or hollow at the top formed by the turning down of the topmost feel or fur, so as much as possible to prevent the removal, to the foot of the rigg, of earth from the higher ground. 12. No tenant shall be entitled to bring upon the lands possessed by him (enclosed or scattald), or to allow to remain thereon, any stock that does not belong to himself, or any halvers stock, or stock that belongs wholly or partially to others, even though such owners or co-owners be members of his own family, without the express leave in writing of the proprietor; but tenants shall be entitled to take for hire cattle to feed on their enclosed lands during summer, or any tenants of parks or islands to take for hire cattle to feed during the year round.
