Predictions Regarding the Tides
During ,he Present Month.
| Probabilities Conc07linJ Retdtiue HigldS.
The afternoon high water, that should begin
the month as the higher with the inequality
in its favor increasingly, will probably attain
its greatest point above the other or Il. m.
high water on about the 9th, whence this
inequality should gradually decrease until
this tide, now Il night high water, equal the
afternoon tide in hight about the 18th.
Thence this afternoon high watcrl should
become the higher, and gradually Increase
the inequality i'll its favor until it reach its
highest point above the morning tide on
about the night of the 18TH and then the inc
quality should again begin to reduce, until
this night high water equal the afternoon
high water on about the 25th, which afternoon
tide should then become the greater.
| Demonstrations for Large and Small Titirs
There should be good tides from July 9Th TO
the 9TH unless depressed by westerly winds.
| especially the night high waters, and those of
| the 7th and Sth small morning high waters
unless aided by easterly winds. from the lith
to the 18th large high waters, unless reduced
| by fresh westerly winds, from the 10Th to the
23d, particularly the night high waters,
and those of the 2lst and 22d and small
morning high waters, unless swollen by
easterly winds, from the to the Both.
REMARKS.
The times of high water published daily in
EVERY EVENING denote the times the tide
| should cease to rise or swell along the
wharves. These figures should also serve for
Edge Moor, Del, and probably for Pcnns-
| grove, N. j.

Besides u great many other people, even sea-
men coming in from the sea, who, in the
| channel away from the shore, have no means
| then, i'll the absence of tide tables, Of observ-
ing high tide, except by the surface current,
| confound this currents ceasing to run, or
| high water slack, with high water itself, when
| the tide may have fallen foot under them
before the current stops. In the Clristana,
this surface current will continue setting up
| for nearly tlree-quarters of an hour after
| high water, if not sooner backed by frcshet
| &C., whilst III the Delaware river in the
Jersey channel, on Edge Moore, Del, it will
| sometimes run up for nearly two hours after
high water there Or here. In this connection,
it may be remarked that this surface currents
| continuing to run an hour or more longer out
in the Delaware river than in the smaller
rivers or creeks emptying into it causes of
course the water to stand where the two sur
face currents meet and hence greater
| deposite of silt or ooze settles at the meeting
points or at the mouths of these smaller
streams. To say nothing of what comes from
| above, at the time of any heavy rain, tons Of
| dirt and even stones are hurried down the
hilly streets into the docks to ill them up,
eventually. 1t is the opinion of those expert
enced in such matters that traps or sinks
We're essential i'll all hillside cities to receive the
dirt sent do yn by rain, which dirt should be
carted of after the silt has settled into mud.
The application of he Tddt Indications II
Other FtdceS.-Those of EVERY EVENINGS
readers who have preserved the ''tidal con-
stants," published in June lists issue, will
observe that, by making the allowances indi-
Gated in this constant table the foregoing
indications for large and small high waters or
their daily inequality can be made to apply
to other points along the Delaware bay and
river. Watermen accustomed to these waters,
who have not this or other constant table
will not forget, III making u calculation for
high water by the swell of 20 miles speed III
the bay and river, that this will lessen further
up the river the tide goes, us the sCa-swCll
will have more fresh water to back mp there,
and i'll the small tributary streams, the speed
is considerably more reduced. For instances III
proceedingu the narrow, crooked 90 miles of
the Cohansey to Bridgeton, the tide swell
travels but some II miles per hour, making
the high water about one and three quarters
hours later ut Bridgeton than ut the
Cohanseys mouth, that is instead OF being
one and u quarter hours earlier than ut VIII
mington, which it probably would be if the
mouth on the Delaware it is because of this
retarding of the swell in that creek but half
hour earlier than here or at the same time the
same high water reaches point very near as
far north as New Castle.
The Effect Of lPi,tds.-1he above indica-
tions are, of course, made without regard to
the effect of winds, whose force and direction
cannot be predicted for any length of time in
advance. Yet by the aid of the Signal Service
Bureaus daily prediction for winds taken in
connection with the representation for large
and small tides and the daily inequality.
published monthly III EVERY EVENING Il good
approximation, It's regards the depth of water
for q hours ahead, ought to be made by
watermen accustomed to frequent the waters
i'll question. 1t may be well to rnnarl hero
that the the winds and storms seem 10 be
much influenced by the tides, changes often
occurring at high or low water. Of course it
depends much on whether the storm is
stronger than the tide or not, but mostly the
tide will hold the wind. This il more
especially apparent i'll the case of the thunder
gusts or squalls of summer. \ thunder
storm, for instance. will split and the one
part come down the Christiana and the other
down the Brandywinc, to unite here aud then,
because it is dead low water say, at night lall,
hang like pail right over the city till the
Hood tide makes i'll the Delaware and
carries the unwelcone visitor on 10
Philadelphia to serenade that city. Those
who have not studied this phenumumun.
r and who yet are interested, can test the
matter here by observing when the storms
arrive on the winds shift and comparing their
times with the times of high or low water.
The low water times can bu approNinatod Ia
by d1ducting, say, 494 hours from EVERY
EyENINd's daily published high water figures
or adding IA hours to them for the following
! low water. Sometimes, however, Il storm is
: strong enough to cross the tide, and some
r times it will not be able tn reach here ut even
, at high water. but will continue on up tho
river on the Hood still prevailing there and
then pass of to the northward and eastward,
/, perhaps not before the tide Gibbs at philadel-
! phia or not before it eliminates ut the head
of navigation, ut Trenton, and then is ebbing
| all along the river and bay, and by that time
! the storm is going to sea across Jersey. and
a Wilmington has escaped its destructive light
, ming hail and fierce wind.
