of the earth,
is called the equinoctial colure; and that which passes through the

ECLIPTIC CONJUNCTION. Is the moon in conjunction with the sun at the
time of new moon, both luminaries having then the same longitude, or
right ascension.

ECLIPTIC LIMITS. Certain limits of latitude within which eclipses take

ECONOMY. A term expressive of the system and internal arrangement
pursued in a ship.

EDDY. Sometimes used for the dead-water under a ship's counter. Also,
the water that by some interruption in its course, runs contrary to the
direction of the tide or current, and appears like the motion of a
whirlpool. Eddies in the sea not unfrequently extend their influence to
a great distance, and are then merely regarded as contrary or revolving
currents. It is the back-curl of the water to fill a space or vacuum
formed sometimes by the faulty build of a vessel, having the after-body
fuller than the fore, which therefore impedes her motion. It also occurs
immediately after a tide passes a strait, where the volume of water
spreads suddenly out, and curves back to the edges. The Chinese pilots
call eddies, chow-chow water.

EDDY-TIDE. When the water runs back from some obstacle to the free
passage of the stream.

EDDY-WIND. That which is beat back, or returns, from a sail, bluff hill,
or anything which impedes its passage; in other words, whenever the
edges or veins of two currents of air, coming from opposite directions,
meet, they form an eddy, or _whirlwind_ (which see). They are felt
generally near high coasts intersected by ravines. The eddy-wind of a
sail escaping, in a curve, makes the sail abaft shiver.

EDGE AWAY, TO. To decline gradually from the course which the ship
formerly steered, by sailing larger, or more off, or more away from
before the wind than she had done before.

EDGE DOWN, TO. To approach any object in an oblique direction.

EDGING OF PLANK. Sawing or hewing it narrower.

EDUCTION PIPE. A pipe leading from the bottom of a steam-cylinder to the
upper part of the condenser in a steam-engine.

EEAST. The Erse term for a fish, still used in the Isle of Man.

EEKING. _See_ EKEING.
