Reg.1 Preamble

       In consequence of the frequent changes which take place in the channel of the principal rivers that intersect the Provinces immediately subject to the 1[Presidency of Fort William] and the shifting of the sands which lie in the beds of those rivers, chars, or small islands are often thrown up by alluvion in the midst of the stream or near one of the banks, and large portions of land are carried away by an encroachment of the river on one side, whilst accessions of land are at the same time, or in subsequent years, gained by dereliction of the water on the opposite side; similar instances of alluvion, encroachment and dereliction also sometimes occur on the sea-coast which borders the southern and south eastern limits of Bengal.

       Whenever any clear and definite usage of shikast paiwast respecting the disjunction and conjunction of land by the encroachment or recess of river may have been immediately established, for determining the rights of the proprietors of two or more contiguous estates divided by power (such as that the main channel of the river dividing the estates shall be the constant boundary between them, whatever changes may take place in the course of the river, by encroachment on one side and accession on the other), the usage so established shall govern the decision of all claims and disputes relative to alluvial land between the parties whose estates may be liable to such usage.
