river where rather different would be from the conditions
those that hold in the open sea. The vertical lines represent the
water's time tall or low forehead to which the tide turned, and
the horizontal lines the height of the tide, but the data want,
clearly, launchings in the different place.

[The illustration: times before turn of tide. Fig tree 10]

You/he/she will be noticed how certain of the points so gotten
is joined above from a regular curve for which can be used
verifying the probable time to which it will turn the tide
on tides of height intermediary to that to that the observations
indeed you/he/she was taken. For example, from the diagram the datum
you/he/she can be seen that on a 20 ft tide the tide will turn thirty
minutes of the tide, or on a 15 ft tide the current wish
you turn a hour in front of the tide. Some of the points lie to a
considerable distance from the regular curve, showing that the
current on those occasions that disturbed were stricken from some
it influences that probably the observer will be able to explain
from a reference to his/her notes, and therefore those particular
observations must be use with caution.

The percentage of trip of the tides varies in agreement with
the time that they is racing. Directly after the turn there
it is as soon as some movement, but speed increases up to that him
you bring a maximum around three hours later and then he decreases
up to that the neighbor turns, when you/he/she happens again dead water.

Those observations of which you start to the turn the
current and it continued through the whole tide you/he/she should be drawn
as shown in Fig tree. 11 that damage the curves related to three
different tides, but, it provided a great staircase it is sufficiently
adopted, there is no reason because it bends related to the whole one
series of the tides should not be drawn on a diagram. This
show of chart the total distance that would be covered by a craft
according to the height of the tide;  it also points out the
the speed of the tide at times. You/he/she can be used in
many ways, but as this the assumption makes necessary that with
