Tide Table,
94
This Table is calculated for the Broomielaw, on the supposi-
tion that the tides are influenced only^by the action of the sun and
moon. It will, therefore, be necessary when using it, to remem-
ber that in rivers, like the Clyde, the regularity of the tides is much
interrupted by heavy rains, as w^ell as by high winds, the former
producing what are called floods or freshes, the latter altering both
the height of the tide and the time of high water.
Heavy rains affect the hour of full tide in a very inconsiderable
degree; but a strong gale from the North- West, North, or North-
East, not only prevents the tide from rising so high as usual, but
causes high water to happen sometimes above half an hour earlier,
than what is stated in the table ; while^ on the other hand, if the
gale be from the South-East, South, or South- West, the tide will
be as much later, and probably from twelve to eighteen inches
higher than the average.
The preceding Table will be applicable to the following places,
if, to the time of High Water at Glasgow, the hours and minutes,
opposite to the given place, be added or subtracted as directed.
