The Chief Commissioner may make rules-
        (a) regulating the manner in which patwaris are to be selected; prescribing the conditions under which they may be appointed; and fixing the limits of their circles and the nature, mode and amount of their remuneration;
        (b) prescribing the conditions under which substitutes may be appointed for persons having hereditary claims to the office of patwari, when such persons are unable to act;
        (c) prescribing the fines which may be imposed on patwaris and their substitutes for neglect of their duty, and stating the circumstances under which they may be suspended or removed:
    Provided that, except with the previous sanction of the Governor General in Council, no proprietor shall be compelled to pay as remuneration to patwaris a sum exceeding six per cent. on the revenue for the time being assessed on his land, or which, when his land is free from revenue, would, in the judgment of the Deputy Commissioner, be assessable on his land if it were liable to assessment.
