Decades of Invention.

the dynamo, and its twin brother, the
electric motor, by Wilde, Slemens,
Wheatstone, Varley, Farmer, Gramme,
Brush, Weston, Edison, Thompson and
others soon brought the great develop
ment of the electric light and electric
railways. Then appeared the Bessemer
process of making steel, dynamite, the
St. Louis bridge, Westinghouse air
brake, and the middhngs purifying the
roller process lin milling. The great
chemist, and probably the greatest
public benefactor, Louis Pasteur, add
ed his work to this period; the Cat
ling gun appeared; great developments
were made in ice machines and cold
storage equipments, machines for
making barbed wire fences; compress
ed air rock drills, and the Mont Gents
tunnel; pressed glassware; Sterns
duplex telegraph and Edison's quad
ralex; the cable car system of Halli-
die, and the Janney car coupler; the
self-binding reaper and harvester; the
temperlng of steel wire and springs by
electricity; the Lowe process OF max
ing water gas; cash carriers for stores,
and machines for making tin cans.
With the next decade (1876-1S86)
there arose a star OF tie first magnitude
in the constellation of inventions. The
railway and the telegraph had al
ready made all people near neighbors,
but>it remained for the Bell telephone
to establish the close kinshdp of one
great talkative family, in constant inv
tercourse, the tiny wire, sentient and
responsive to the familiar voice, trans
mlttlng the message with tone and ac-
cent unchanged by the thousands of
miles of distance between. Then come
in order the hydraulic dredges, and
Mississippi jetties of Eads; the Jab-
lochkoff electric candle; photography
by electric light; the cigarette machine
the Otto gas engine; the great i'm
provement an development Of the type
writer; the casting of chilled car
wheels; the Birkenhead & Babbeth
spinning spindles, and enameled sheet
iron ware for the kitchen Next the
phonograph of Edison appears, literal
ly speaking for itself, and reproduc-
ing human speech and all sounds with
startling fidelity. In this decade we
also find the first electric railyaw op-
GRATED in Berlin; the development of
the storage battery; welding materials
by electricity; passenger elevators; the
construction of the Brooklyn bridge;
the synthetic production of many use
full medicines, dyes and antfseptics
from coal tar products, and the Cowles
process for manufacturing aluminium.
In the last decade (1SS6-1896) inven-
tions in such great numbers and yet
of such importancel4ave appeared that
selection seems impossible without do
ing injustice to the others. The graph
ophone; the Pullman and Wagner rail-
way ears ond Yestibuled trains; the
Harvey process of annealing armor
plates; artificial silk from pyroxyline;
automobile or horseless carriages; the
Zalinski dynamite gun; the Mergen-
thaler linotype machine, moldipg and
setting its own type, whole bins at a
time, and doing the work of FOUL Com
positors; theWelsbach gas burner, the
Krag- -JorgenseD rifle; Professor Lang
ley's aerodrome; the manufacture of
acetylene gas from calcium carbide; the
discovery of argon; the application OF
the cathode rays in photography by
Roentgen; Edisons microscope for
seeing with the cathode rays; Tesle s
discoveries in electricity, the kineto-
scope, are some of the modern inven-
bions which still interest and engage
the attention of the world, while the
great developments in photography
and of the web pertecting printing
press, the ypewriter.-Inventive Age.

case OF bronchitis, lung affection and grippe
Physicians prescribe this reliable remedy, and
druggists recommend 1t; because IL never
fails to cure, and costs but 20 cents q bottle.
