THE COMING SQUALL.

Tides:

Roughly speaking, the tide is one hour later every day. It is theoretically high when the moon bears directly South, either on one side of the world or the other, but actually the friction of the water causes a retardation which delays the wave until sometime after the moon has made its southing.

Tides:

Channels open at both ends have generally very strong tidal currents, but a small rise and fall. The highest tides are in funnel-shaped bays or estuaries directly open to the sea. The day tides are generally higher than those at night.

High water:

High water does not in many cases coincide with the stop of the current. In places situated upon sounds, channels and passages, the current continues to flow long after it is high water. The same with the ebb, which runs after the tide has reached its lowest level.

High water:

Frequently the tide is not found to be high at the time given in the tables, and very often the current does not turn at the hour and minute predicted. This does not prove that the tables are unreliable or worthless. The tide is frequently prolonged or retarded by the wind, which, acting either with or against it, causes the current to run with greater or less force.
