From Middle English scǒuren (“to polish, scour; to clean; to beat, whip”), from Middle Dutch scuren, schuren (“to clean; to polish”) or Middle Low German schǖren,^[1] of uncertain origin but probably from Old French escurer, from Medieval Latin scūrō, escūrō, excūrō (“to clean off”), from ex- (“thoroughly”) + cūrō (“to arrange, see to, take care of”),^[2] from cūra (“care, concern”) (from Proto-Indo-European *kʷeys- (“to heed”)) + -ō.

The word is cognate with Danish skure, Middle High German schüren, schiuren (modern German scheuern (“to scour, scrub; to chafe”)), Norwegian skura (“to scrub”), Swedish skura, Catalan escurar.

     It has already been explained that the ebb tide in the Hooghly is a much more powerful scouring agent than the flood tide, that the tide therefore should be used for scouring a channel in preference to the flood whenever it is practicable to use it, hence it is to the body of ebbing water that scours out the fine channel from Akelmeg to Crossing Creek that attention will be principally directed, and not to the flood that scours the channel near the Roopnarain entrance.

     The general manner of working this sluice is to take in every alternate tide during the high tides in dry weather, and to let them off for scours for the harbour. In wet weather, or during neap tides, no scours are kept back, nor is it of any consequence to the harbour if no tides are suffered to pass up through the sluice at such times.
