| method by which the captain OF snip
in mid-ocean can find his exact posi-
tion in latitude and longitude, by the
use of wireless and without the aid OF

perfected by member of the unlteu

chiefly as Spectator in copper mines
/ and figure in so-called copper war.
| Probably comparatively few oil these
who know Clements as a man OF busl-
ness are aware that he graduated from
the naval academy at Annapolis BACK
in 1875. and that he was an offlctl IN
the navy for II years, He spent sew
eral years at the naval observatory at
Washington studying astronomy ana
| navigation in business hours ana Jaw
out Of business hours. When he had
finished his legal education he SAID
good bye to the navy and entered busl-
ness life.
There was nothing unusual about that
great many young men OF ablllty
were lea wing the navy about that time,
because promotion was extremely SLOW.
The Civil war had created glut or
officers. The situation in respect to
promotion was much the same as that
which naval academy graduates or thls
and the next few years VIII race.
The unusual feature of Clements
case Is that although he left the navy
he did not neglect the science OF
mathematics and astronomy which had
| fa gpiD1 ed him student. During
| the most strenuous phases of some
| what spectacular career in finance, ne
| found his recreation in working out
| problems in ballistics, navigation, ana
astronomy. The formuae OF calculus
and trigonometry, which the average
college man forgets within three years
! of his graduation, Clements was still
using as playthlngs 30 years after he
! had severed his connection with the
navy That relief from business worry
! which other men found in dissipation
and sport he got with far less waste OF
stars and advising rifle manufacturers
! how to make barrels that would give
the projectile flat trajectory
