surveyor and scientist.
In the book Ma'. Gu'hrie sets out
the McDuffie family history and gives
the explanation made by McDuffie as
to the natural causes of the varia
tions of the Magnetic Needle, a mat
ttr fxed by no other scientist. The
author holds that if McDuffie is right,
then that if Dr. Cook or fnmminler
pearv had only the Magnetic Needle
as a guide, that they may have
reached the North Magnetic Jo:e by
its aid, but with McDuffie right, "they
would jtill be a long way off from the
North Pole of the axis of the earth."
The entire book, of thirty-six pages
in rdze, is full of interest to both sci
entist and layrran, and there is here

Guthrie says that McDuffie was his
old familiar friend, a surveyor of Fay
etteville, that together . they spent
much time in the woods of. the Uppe
Cape Fear in hunting for. landmarks
to determine boundaries in dispute,
that in his opinion McDuffie "was the
greatest mathematical genius, the
most learned surveyor and the best
and most expert woodsman in finding
h-nlmarks" he ever met, that he says

was not the lowest.
In his close acquaintance he tells
of hearing McDuffie discussing the
subject of the Magnetic Needle in a
scientific way and that later at his
request more than twenty years ago
wrote out his very decided view's
concerning it, believing he had made

St-ll your poorest horse an-1 l;i;- a

10 minutes (41 deg., 9 min. and 46
sec.) south of the North Pole, we
again have a right angle triangle with
one side and all the angles
given to find the side re
quired which will be the radius of
of the circle required. By the London
calculation measuring from the pole
of the earth to the magnetic polo
amounts to 13.07'100 decrees; by the
laris calculation the amount i
15.73-100 degiees. There should be
no discrepancy; but for the present
taking the mean, which is 13 degrees
-ml 5 4 minutes, and this taken from
90 degrees equals 7 4 degrees and 6
m!nutts. Now, what is necessary in
order to find how long it will take the
rarth to make the revolution and at
the same time to prove that it does
make it, or that the magnetic pole
makes a revolution around the pole
of the earth? As above stated. Lon
don or Greenwich was on an agonic
line in 1657, and this being zero point
or the place from which longitude is
reckoned, Ihen. we will select, for in
stance. New Pern, North Carolina, as
a place which is 77 degrees West of
London. The agonic line reached this
place (New Pern, N. C), in 1840, that
.is, the magnetic pole had passed over
77 dfgrees in 1S: years, and if it
passed over ii degrees in lvj years,
it will pass over 360 degrees (or com
plete the circle) in 855.58 years. Or
to state it by a rula of proportion, it
would be thus: As 77 degrees is to ;'(.
degrees, so is 1S3 years to 85 5.58
years, or make a complete revolution.
(77:360- -183:855.58 years.)
"Jn the above calculation New Pern.
C. is merely selected for illustra
tion, for after many calculations foi
different localities, it will be foun.l
that 85 6 years i- the time required lor
a complete revolution of the magnetic
pole around the pole of the earth.
Put it must be remembered that
Greenwich will again be on an agonic
l ne in one-half" that time, or in 428
years, wMch will be in A. D. 2085.
That the sun and rarth are beth mag
netic is now admitted by all scientific
men, anel being magnetic must have
positive and negative poles. Put as
terrestrial macnetism has been so ful
ly explained by Gauss and others, 1
need net undertake to prove an ad
mitted fact that the needle is govern
ed by the same magnetic law that go -erns
the sun and earih.

thy would still be a long way off
from the North Pole of the axis of
the Earth. And if tha North Mag
netic Polo in its 836 years' .ouraey
around the North Pole, which Mc
Dutfie has calculated from given eiata,
in making its revolution around th
Pole, describes a circle around the
North Pole of the Earth, the question
then arises, how can the actiial dis

to the North Pole of the Earth be as

od of finding the length oi the ramus
of the circle which the North Mag

Pole of the Earth, anel Ly his method
of calculation finding its center, winch
would be, geographically speaking,
