When land added by alluvial accession to an estate paying revenue to Government becomes liable to assessment, if it be so agreed on between the Revenue-authorities and the proprietor or proprietors, the revenue assessed upon the alluvial land may be added to the jama of the original estate; and in such case a new engagement shall be executed for the payment of the aggregate amount, and that amount shall be substituted in the Collector's rent-roll for the former jama of the original estate.

If the proprietor or proprietors object to such an arrangement, or if the Revenue-authorities are of opinion that a settlement of the alluvial land cannot properly be made for the same term as the existing settlement of the original estate, the alluvial land shall be assessed and settled as a separate estate with a separate jama, and shall thenceforward be regarded and treated as in all respects separate from and independent of the original estate, whether the separate settlement be made with the proprietor or proprietors or the land be let in farm in consequence of the refusal of the proprietor or proprietors to accept the terms of settlement.

The separate settlement may be permanent, if the settlement of the original estate is permanent.
