THE FUTURE.
The history of wireless telegraphy and telephony is a striking example
of how it is possible for scientists laboring in the field of pure
research and stimulated by accumulated knowledge and imagination to
arrive at discoveries of the most vital importance. Heinrich Hertz and
Clerk Maxwell in experimental effort to attain other results unwittingly
laid the foundation of this art.
In 1867 Maxwell proposed the theory that light is not mere mechanical
motion of the ether, but consists of electrical undulations. These
undulations are partly magnetic and partly electrical. Moreover,
according to the theory, the phenomena of electromagnetism and also that
of light are due to certain modes of motion in the ether, electric
currents, and magnetism, being due to whirls, or body displacements in
the substance of the ether, while light is due to vibrations to and fro.
Twenty years later Hertz discovered the most convincing experimental
proofs of Maxwell's wonderful theory, and succeeded in producing
electromagnetic waves in such a manner that their propagation through
space could be examined, and it readily showed that while they were much
longer than the ordinary waves of light, they possessed the same
properties, were capable of being reflected, polarized, refracted, etc.,
and traveled at the same speed.
The waves that Hertz produced are the electromagnetic or Hertzian waves
of radiotelegraphy.
Many thousand commercial wireless stations dot the face of the earth.
Daily time signals, weather reports and storm warnings flash to ships
far out in the ocean from government observatories. Late at night, in
the midnight hours, when the world is asleep, powerful land stations
commence to whisper press dispatches, and the next morning the ocean
daily, containing the same news as our morning paper, is laid on the
breakfast table of the ocean greyhound. A distress signal sends revenue
cutters scurrying along the coast, and brings rescue to hundreds of
imperiled lives. The Navy Department issues an order, and a few minutes
later it is in the hands of the commanding officer of a fleet, a
thousand miles away. Wireless links two continents across a table, and
yet this wonderful apparatus is so simple that a sixteen-year-old boy
can build instruments with a little guidance and listen to a far-distant
station, 1,500 miles away, spell out its news.
[Illustration: FIG. 150.—An amateur wireless telegraph station.]
[Illustration: FIG. 151.—The high-power Naval wireless telegraph
station under construction at Washington, D. C.]
Wireless telegraphy is part of the established order of things. The
wireless telephone is practical for limited distance, but is not a
commercial rival of the telegraph. Great distances are claimed, but they
are matters for proof and speculation.
There is no immediate possibility that wireless telephony will take the
place of local exchanges. If the time ever does come that it in any way
tends to supplant the line telephone for some uses, it is more than
probable that each subscriber must have his own generating station and
call up direct.
There is a very decided field of opportunity for wireless telephony for
long-distance work. The present systems of long-distance wires are very
expensive to construct and maintain, and are subject to the whims of
storms and the elements.
Wireless telephones will not only transmit the speech more clearly and
distinctly, but have the further advantages that the initial cost is
very much lower than that of wire lines, the maintenance is almost nil
in comparison, the depreciation is smaller, the number of employees
required is less, and a break-down is limited to the inside of the
station, where it could be quickly remedied by the substitution of a
duplicate spare piece of apparatus.
Furthermore, no franchises or rights of way would need to be purchased.
No serious difficulty would be encountered because of interference.
Wireless telephony, like wireless telegraphy, but to an even greater
extent, is peculiarly suited for the conveyance of marine intelligence.
Wireless telephony occupies a unique position in this regard-no operator
is required. The additional expense of an operator is an objection to
the wireless telegraph in many cases, and forbids its installation.
Anybody can operate the wireless telephone. It is also much
quicker-words can be spoken more rapidly than they can be put into Morse
signals and translated.
[Illustration: FIG. 152.—--The curved lines represent the radius of
the government high power wireless stations and show the zones over
which direct communication may be had with ships.]
[Illustration: FIG. 153.—The aerial system of a transatlantic station.]
The wireless telephone enables a passenger on board ship to communicate
direct with his home by relaying the message over the line wires. By the
same means the captain of a ship can call his home office and
communicate with the owner of the vessel.
Telegraphs and telephones are the nerves of the world, carrying swift
messages from its brain centers to its hands, annihilating distance in
thought. All differences between men as individuals and people as
nations can be traced to the lack of close contact. Reduce or annihilate
all distance in thought and action, and mankind would possess unbounded
opportunities for peaceful economic and healthful development. No force
more vital than the possibilities of wireless has ever presented itself
or could be demanded to attain such an end. Such a statement, in the
light of actual developments, might even be considered conservative, and
is neither absurd nor the dream of a vivid imagination. The greatest
obstacle to all efforts in radically new directions is the resistance of
the human race. The antagonism of prejudice and skepticism can only
disappear when the world as a whole grasps a new proof and learns to
appreciate it. Inertia must be overcome, and the great masses set to
thinking and striving toward an end before the aweing genie finally
bursts forth and amazes the Aladdins of science.
Within the memory of older men and women are primers of science, which
speculate about the developments of electrical force, and guardedly
discuss its possibilities.
And now, electricity—this mysterious agent-has multiplied the muscular
strength of man a billion times. The tasks of Hercules are now but
chores to be accomplished by the closing of a switch. Mighty rivers roar
through intake and turbine to drive the wheels of industry in a distant
city and turn the night into day. Any attempt to chronicle all the
applications of this wondrous power would be absurd. Such is electricity
to-day.
Only a few years ago Langley launched his famous aerodrome over the
waters of the Potomac, while the world stood by and sneered, ridiculed a
man whose work is now one of the classics of aeronautical literature,
and scoffed at a machine whose principles embodied the conclusions of
years of careful thought and scientific effort.
A decade later and aeroplanes have become a living reality. A man and a
little frame of sticks and canvas can throw off the fetters of gravity
and go soaring dizzily two miles up into the blue sky, and daring more,
come skimming and diving back to earth with motor dead. Such wonders
only came to pass, however, when numbers of men accepted the problem as
one to be solved by trying, and bent their energies toward its solution.
Science has not reached the limits of its resources. It never will. The
art of wireless may always be embarrassed by novelty in many directions.
[Illustration: FIG. 154.–Fong Yee, a Chinese amateur wireless operator
at Oakland, Cal., who is also an aviator and has been summoned home by
the republican Chinese government to demonstrate apparatus of his own
invention to the Chinese army.]
One of the greatest steps forward toward the day when methods and
appliances regarded as permanent as the mountains will pass and be
considered only as the curious remnants of a cruder age is the interest
of 200,000 wireless amateurs in the United States. Some of these will
develop into men who will bring some of the wonders of the future to
their full fruition.
[Illustration: FIG. 155.—Tesla world power plant (experimental
station).]
What is this great change that can be coolly and precisely forecast?
Along what lines will these wonderful developments come? The answer is
"wireless"-not the wireless of a Marconi or a De Forest, but the
wireless of a Tesla--of "high potential magnifying transmitters"-of
"nodes" and "loops"--of oscillatory currents that leave their conductors
behind-the "wireless" of the day when a system is introduced enabling
any person to reach any other on the globe, not simply through a spoken
word or thought conveyed, but visually a perfect transmission of images
which will enable one person to see another, as though that other were
by his side-"wireless" of a time when the great operations of commerce
and industry will be vitalized by huge wireless power stations, turning
the machinery of factories, lighting cities, or sending swift aeroplanes
and ships darting to the farthest points of the earth.
Of course, there may be something of the dramatic in such assertions,
but they are founded upon scientific facts, and, if imaginary, are
scientifically imaginary. The wonderful mysteries of oscillatory
currents, whose natural medium is the ether, currents which object to
being confined to wires and cables, and defy all ordinary laws; currents
that will melt masses of metal with the violence of an explosion, but
yet pass through the human body without producing any sensation;
currents that will instantly manifest themselves 2,000 miles away from
their source, with no visible means of propagation, are the open sesame
to the treasures of a wonderful future.
There are many places in the world where water power is available
capable of generating almost unlimited electrical energy. The present
difficulty lying in the way of its utilization is the limitation of
electrical transmission by wire, for not only is the cost of long lines
of copper tremendous, but power can only be carried in this manner for
limited distances. Central distributing wireless power stations could
send the power of Niagara, which alone might be made to supply a fifth
of all the power in the United States, and the energy of Victoria to the
ends of the earth with little loss. The Great Falls of Zambesi, in the
heart of Africa, could be made to run the subway trains, the factories,
lights, railroads, ferries, trucks, heaters, etc., in that vast, most
complex, most bewildering and inspiring city of the Western World, the
City of New York. Ocean vessels would no longer carry thousands of tons
of coal, locomotives would not wheeze and cough a trail of soot and
smoke through the country, chimneys would cease to belch, and aeroplanes
would travel silently and swiftly overhead.
[Illustration: FIG. 156.—Twenty-five foot sparks from a Tesla
transformer.]
It is easy, in the face of certain facts, to conjure up situations which
would be pleasant and make for the betterment of the world. Any one
whose imagination is vivid enough can make a prediction, but when the
great truth is accidentally revealed, or experimentally confirmed, as
the case may be, and rendered absolutely sure of accomplishment, will
its incalculable consequences continue to baffle the imagination and
carry us further into the land of wonderment? Only the future knows.

DROP FORGING, DIE SINKING AND MACHINE FORMING OF STEEL. By J. V.
WOODWORTH.
This is a practical treatise on Modern Shop Practice, Processes,
Methods, Machines, Tools, and Details, treating on the Hot and Cold
Machine-Forming of Steel and Iron into Finished shapes; Together with
Tools, Dies, and Machinery involved in the manufacture of Duplicate
Forgings and Interchangeable Hot and Cold Pressed Parts from Bar and
Sheet Metal. This book fills a demand of long standing for information
regarding drop forging, die-sinking and machine forming of steel and the
shop practice involved, as it actually exists in the modern drop forging
shop. The processes of die-sinking and force-making, which are
thoroughly described and illustrated in this admirable work, are rarely
to be found explained in such a clear and concise manner as is here set
forth. The process of die-sinking relates to the engraving or sinking of
the female or lower dies, such as are used for drop forgings, hot and
cold machine forging, swedging and the press working of metals. The
process of force-making relates to the engraving or raising of the male
or upper dies used in producing the lower dies for the press-forming and
machine-forging of duplicate parts of metal.
In addition to the arts above mentioned the book contains explicit
information regarding the drop forging and hardening plants, designs,
conditions, equipment, drop hammers, forging machines, etc., machine
forging, hydraulic forging, autogenous welding and shop practice. The
book contains eleven chapters, and the information contained in these
chapters is just what will prove most valuable to the forged metal
worker. All operations described in the work are thoroughly illustrated
by means of perspective half-tones and outline sketches of the machinery
employed. 300 detailed illustrations. Price $2.50
DRAWING-SKETCHING PAPER

SELF-TAUGHT MECHANICAL DRAWING AND ELEMENTARY MACHINE DESIGN. By F. L.
SYLVESTER, M.E., Draftsman, with additions by ERIK OBERG, associate
editor of "Machinery." This is a practical treatise on Mechanical
Drawing and Machine Design, comprising the first principles of geometric
and mechanical drawing, workshop mathematics, mechanics, strength of
materials and the calculations and design of machine details. The
author's aim has been to adapt this treatise to the requirements of the
practical mechanic and young draftsman and to present the matter in as
clear and concise a manner as possible. To meet the demands of this
class of students, practically all the important elements of machine
design have been dealt with, and in addition algebraic formulas have
been explained, and the elements of trigonometry treated in the manner
best suited to the needs of the practical man. The book is divided into
20 chapters, and in arranging the material, mechanical drawing, pure and
simple, has been taken up first, as a thorough understanding of the
principles of representing objects facilitates the further study of
mechanical subjects. This is followed by the mathematics necessary for
the solution of the problems in machine design which are presented
later, and a practical introduction to theoretical mechanics and the
strength of materials. The various elements entering into machine
design, such as cams, gears, sprocket wheels, cone pulleys, bolts,
screws, couplings, clutches, shafting and flywheels have been treated in
such a way as to make possible the use of the work as a textbook for a
continuous course of study. It is easily comprehended and assimilated

ELECTRIC FURNACES AND THEIR INDUSTRIAL APPLICATIONS. By J. WRIGHT This
is a book which will prove of interest to many classes of people; the
manufacturer who desires to know what product can be manufactured
successfully in the electric furnace, the chemist who wishes to post
himself on the electro-chemistry, and the student of science who merely
looks into the subject from curiosity. The book is not so scientific as
to be of use only to the technologist, nor so unscientific as to suit
only the tyro in electro-chemistry; it is a practical treatise of what
has been done, and of what is being done, both experimentally and
commercially with the electric furnace. In important processes not only
are the chemical equations given, but complete thermal data are set
forth and both the efficiency of the furnace and the cost of the product
are worked out, thus giving the work a solid commercial value aside from
its efficacy as a work of reference. The practical features of furnace
building are given the space that the subject deserves. The forms and
refractory materials used in the linings, the arrangement of the
connections to the electrodes, and other important details are
explained. 288 pages. New Revised Edition. Fully illustrated. Price
