determine dimensions, distance, or capacity; a standard.

4. (Physics) Any instrument or apparatus for measuring the
state of a phenomenon, or for ascertaining its numerical
elements at any moment; -- usually applied to some
particular instrument; as, a rain gauge; a steam gauge.
(a) Relative positions of two or more vessels with
reference to the wind; as, a vessel has the weather
gauge of another when on the windward side of it, and

6. The distance between the rails of a railway.
Note: The standard gauge of railroads in most countries is
four feet, eight and one half inches. Wide, or broad,
gauge, in the United States, is six feet; in England,
seven feet, and generally any gauge exceeding standard
gauge. Any gauge less than standard gauge is now called
narrow gauge. It varies from two feet to three feet six

1. Time; period; season. [Obsoles.] “This lusty summer's
And rest their weary limbs a tide. --Spenser.
Which, at the appointed tide,

2. The alternate rising and falling of the waters of the
ocean, and of bays, rivers, etc., connected therewith. The
tide ebbs and flows twice in each lunar day, or the space
of a little more than twenty-four hours. It is occasioned
by the attraction of the sun and moon (the influence of
the latter being three times that of the former), acting
unequally on the waters in different parts of the earth,
thus disturbing their equilibrium. A high tide upon one
side of the earth is accompanied by a high tide upon the
opposite side. Hence, when the sun and moon are in
conjunction or opposition, as at new moon and full moon,
their action is such as to produce a greater than the
usual tide, called the spring tide
, as represented in
the cut. When the moon is in the first or third quarter,
the sun's attraction in part counteracts the effect of the
moon's attraction, thus producing under the moon a smaller
tide than usual, called the neap tide
Note: The flow or rising of the water is called flood tide,
and the reflux, ebb tide.
3. A stream; current; flood; as, a tide of blood. “Let in
the tide of knaves once more; my cook and I'll provide.”
4. Tendency or direction of causes, influences, or events;
There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune.
5. Violent confluence. [Obs.] --Bacon.
6. (Mining) The period of twelve hours.
, tidal movements of the atmosphere
similar to those of the ocean, and produced in the same
manner by the attractive forces of the sun and moon.

, v. t.
, the interval between the occurrences of two
consecutive maxima of the resultant wave at the same
place. Its length varies as the components of sun and moon
waves approach to, or recede from, one another. A
retardation from this cause is called the lagging of the
tide, while the acceleration of the recurrence of high
water is termed the priming of the tide. See Lag of the tide

, a dial to exhibit the state of the tides at any
(a) An opening through which water may flow freely when
the tide sets in one direction, but which closes
automatically and prevents the water from flowing in
the other direction.
(b) (Naut.) A place where the tide runs with great
velocity, as through a gate.
, a gauge for showing the height of the tide;
especially, a contrivance for registering the state of the
tide continuously at every instant of time. --Brande & C.
, a lock situated between an inclosed basin, or a
canal, and the tide water of a harbor or river, when they
are on different levels, so that craft can pass either way
at all times of the tide; -- called also guard lock
. (a) A mill operated by the tidal currents.
(b) A mill for clearing lands from tide water.
, a body of water made rough by the conflict of
opposing tides or currents.
, a table giving the time of the rise and fall of
the tide at any place.
, water affected by the flow of the tide; hence,
broadly, the seaboard.
, or Tidal wave
, the swell of water as the tide
moves. That of the ocean is called primitive; that of bays
or channels derivative. See also tidal wave
, a water wheel so constructed as to be moved by
the ebb or flow of the tide.
