nearly opposite points on the earth's surface,
where the Clip OF the needle is 80 degrees. They
are at a considerable distance from the geo.
graphical poles OF the earth. The north magnetic
pole was first distinctly located at BOOthia
Felix. a peninsula of British North America,
between latitude 90 and 72 north and loBgi-
tude 80 and 81 west. 1t was discovered by
Captain (afterward Sir James, ROSS IN 1880.
The magnetic north, that point which is ind-
Gated by The direction of the magnetic needle,
is seldom the true north. Why the magnetic
needle points 10 the north was recently eX-
planned as follows by Professor &. T. Patterson
of The United States Coast Survey: "The earth
is itself magnet and attracts the needle just
as an ordinary magnet does. IL Is found TO be
affected by the action of the sun in a man
ner not yet fully understood. The mag
netic poles OF the earth are not in
line with the geographical poles. but make an
angle with them of nearly % degrees. AT the
present line the northern magnetic pole is near
the Arctic circle, on the meridian OF Omaha,
and from the nature OF the case the pole NAV be
better described as a region than as fixed
fact. The needle does not everywhere point TO
the true NORTH but varies within certain limits.
At San francisco 1t points II degrees east of
north, and at Calais, Me- as much to the west.
At the northern magnetic pole a balanced
needle points with Its north end DOWN. ara in
plumb line: at San francisco 1t dips about SO
degrees, and at the southern magnetic pole the
south end points directly down. The action OF
the earth upon magnetic needle al Its surface
Is OF about the same force as that of a hard steel
magnet forty inches long, strongly magueIiZed.
