5. The proprietor reserves all trout fish in the lochs and burns on his lands, and sole right to fish therefor; and every tenant shall be held specially to consent, and shall be expressly bound and obliged, alike as regards himself and all in family with him, to abstain from fishing for trout (fresh-water or sea-trout alike) in all fresh-water lochs, waters, and burns, and also in all burn-mouths into which the sea-water may flow, and in all voes, inlets, or bays, though consisting wholly or partially of salt or sea-water, into which any fresh-water lochs or burns flow, and bounded wholly or partially by lands belonging to the Busta estate; and shall in no way take, or attempt to take (by rod, net, cruive, or hoovie, or in any other way), any trout fish therein, unless with the express leave of the proprietor; and when such leave extends to fishing by net, then with a net of the size of mesh, used in the manner, and at the time, and to the extent, expressly allowed and prescribed by him. 6. All tenants shall be bound, if required, to pay, over and above their stipulated rents, their proportion of all public and parochial burdens which the law has laid, or may lay, directly upon tenants, any custom to the contrary notwithstanding. 7. No office house must, hereafter, be erected on the side or end of a dwelling-house, without the written permission of the proprietor; and no tenant shall be entitled to remove from out the dwelling-house or offices possessed by him at the expiry of his lease, any roof, window, door, loft, stair, or other plenishing of a like fixed nature, even though furnished and put in by himself, unless his tack specially confers upon him such power; but the incoming tenant shall be bound to pay the outgoing tenant the value of the roofs, windows, and doors of the office-houses, if such roofs, doors, and windows were paid for by him at entry, or furnished by him during his lease. 8. Every tenant shall be bound, throughout the whole currency of his tack, to maintain good and sufficient dykes of every sort, including yard dykes, and to maintain sufficient and convenient grinds in his dykes at all places usual and needful, and to have all dykes in thorough and sufficient repair, and all grinds sufficient and properly hung, at the latest on or before the first day of April, and to keep up said dykes and grinds until the first day of November in each year. 9. That in the event of any tenant not keeping dykes and grinds in sufficient order, the proprietor shall be entitled to enter upon the lands, and to repair the same, and to charge the tenant 10 per cent. on the sums expended by him in said repairs; and the amount shall be held as conclusively ascertained and fixed by a certificate thereof, under the hands of the factor on the estate of Quendale for the time.
