(1) When in the opinion of the Collector or of an officer making a general re-assessment of land-revenue under the foregoing provisions of this Chapter, the waste-land belonging to or adjoining an estate is so extensive as to exceed the requirements of the owners of the estate with reference to pasturage or other useful purpose, the Collector or officer may at any time, with the previous sanction of the Financial Commissioner, make a separate assessment of the waste-land which he considers to be so in excess, and offer that land at that assessment, for such term and on such conditions as he thinks fit, to the owners of the estate to which it belongs, and, if they refuse the offer, to the owners of any estate which the land adjoins, and, if they also refuse the offer, to any other person.
(2) When the owners of the estate to which the waste-land belongs refuse the offer, the Collector shall assign to them an annual allowance not less than five and not more than ten per cent. of the net income realized by the Government form the land.
