I do not know whether it
will tolerate cultivation; if so,
it would make a welcome
addition to our cultivated
clematis.

One of the uncommon
plants which bloom on the
higher levels of our moun-
tains, and rarely seen except
by those young and_ hardy
enough to climb to those
higher heights is the Luina

orded from Crown Mountain.
Its white tomentose leaves
‘and fine corymbose yellow
flowers make it well deserv-
ing of the description which
Henry gives it—‘a beautiful
mountain plant”’.

arly Electric Light on This Coast

HE name Electricity was given to that subtle force of Nature which gives us of

today the artificial light of night-time and the power derived through the use of

the dynamo in our industries, by Dr. Gilbert of Colchester, England, about 1600.
It was derived from the Greek word meaning amber.

But that property which amber possesses in such a high degree had been known to
the ancients for many centuries before the time of Gilbert. Nevertheless, it was not
placed in the service of mankind until within comparatively modern times. Scores of
scientific men had assisted in solving something of its nature and of its latent powers,
adding little by little their quota of discovery which has led us to the achievement
of its present uses.

Of that long list of notable men we shall mention only a few, whose work stands
as stepping-stones across a shallow stream, enabling us to arrive at the goal of today.

Hans Christian Oersted, a Danish scientist, demonstrated conclusively a fact which
he had long suspected, during a lecture to his class of students at Copenhagen in
1820, that electricity and magnetism were closely related. This opened new lines of
research in what proved to be fruitful fields. In 1831, Michael Faraday, following
along these lines, discovered the principle of electric induction, the doorway to a
series of brilliant experiments which have rendered his name immortal. But it fell
to Charles Francis Brush to build the first really practical electric dynamo, in 1875.
This he placed before the public in 1876, together with the idea of the electric
Arc Lamp, connected in series, which soon became the parent idea of our Street
Arc Lamp. It is this idea with which we propose to deal in this short outline of the
introduction of electric light to B. C.

Mr. Brush was born March 17, 1849, at Euclid, Ohio, attended the public schools
of Cleveland while living on a farm near that city, afterwards being graduated from
the University of Michigan. He opened his own laboratory in Cleveland, shortly
after which he built the historic Brush Dynamo, a 500-volt Direct Current machine
Operating at approximately 50 volts; arc lamps in series, of estimated 2000 candle-
