petency will, in addition to the present requirements
for these grades, be required to pass an examination
in the subjects specified below.

In Navigation.--A second mate will be required to
find the time of high water at a given port; to observe
and calculate the amplitude of the sun, and to find
the error of the ship's compass therefrom; and also
the deviation, the variation being given. He must
also be able to find the daily rate of the chronometer
from error observed, and to find the longitude by
altitude of the sun by the usual methods.

An only mate will be required to find the true
bearing of the sun, and the error of the ship's com-
pass from an observed azimuth of the sun, both from
an altitude and also from the "Time Azimuth Tables,"
and with the variation given compute the deviation;
to find the latitude from a single altitude of the sun
off the meridian, and also to ascertain the true bear-
ing of the sun and the ship's position by Sumner's
method by projection. He must also be conversant
with the use of Mercator's chart, and be able to find,
on either a true or magnetic chart, the course to
steer, and the distance from one given position to
another; to find the ship's position on the chart from
cross-bearings of two objects; from two bearings of
the same object, the course and distance between the
bearings being given; and also to find the distance
of the ship from the object at the time of taking the
second bearings.

A first mate will also be required to find the true
bearing of the sun from the "Time Azimuth Tables,"
and with the variation given compute the deviation,
and also work out the same problems, on either a
true or magnetic chart, as are required of a candidate
for an only-mate's certificate. (See above.)

A master will also be required to find the true
bearing of the sun from the "Time Azimuth Tables,"
and with the variation given compute the deviation,
and work out the same problems, on either a true or
magnetic chart, as are required from the only or first
mate. He will also be required to find the course to
steer by compass in order to counteract the effect of
a given current, and to find the distance the ship will
make good towards a given point in a certain time,
and to work out practically the correction to apply
to soundings taken at a given time and place, to com-
pare with the depth marked on the chart.

In Seamanship.--Besides the subjects already pre-
scribed in the rules for the ordinary examinations,
candidates for second, only, first mates', and masters'
certificates of competency will be required to give
satisfactory answers as to their knowledge of the
additional subjects (applying more particularly to
steamships) which are specified in the rules of
examination for certificates of competency for
foreign-going steamships.

The red light is cut downwards, and is obscured
when approaching from seawards until four miles
distant from the lighthouse, the light bearing N. by
W., and will be visible until run out at eight miles
distant on a course bearing W. by S. or E. by N.
Caution: The red light is exhibited to warn mariners
of approaching danger, and when seen the course
should be altered to run it out. In hazy or misty
weather mariners should not rely upon sighting the
red light, but should keep a good offing.
