it should, however, be notea that this la t change only
affected the bed of the river below Vi 1 ak and that the
bed from Kuhak to lilak has remained unchanged.
From the above it appears that the .eriod of 44 years
winch has elepsed since the last change is a longer ^eriod
than usually elapses between changes of course. Assuming
that the factors making for a change in course have remained
constant, it is not unlikely that a new change within the
Northern delta may now be imminent, a a the methoas at
present employed to control the river are in no **ay superior
to there which have been used for the la at 1000 years.
