of the privileges of all civilised governments。 When the ``edited''
telegram was printed�察�the good people in Berlin felt that
their old and venerable king with his nice white whiskers had
been insulted by an arrogant little Frenchman and the equally
good people of Paris flew into a rage because their perfectly
courteous minister had been shown the door by a Royal Prussian
flunkey。
And so they both went to war and in less than two months��
Napoleon and the greater part of his army were prisoners of
the Germans。 The Second Empire had come to an end and the
Third Republic was making ready to defend Paris against the
German invaders。 Paris held out for five long months。 Ten
days before the surrender of the city�察�in the nearby palace of
Versailles�察�built by that same King Louis XIV who had been
such a dangerous enemy to the Germans�察�the King of Prussia
was publicly proclaimed German Emperor and a loud booming
of guns told the hungry Parisians that a new German Empire
had taken the place of the old harmless Confederation of Teutonic
states and stateless。
In this rough way�察�the German question was finally settled。
By the end of the year 1871�察�fifty´six years after the memorable
gathering at Vienna�察�the work of the Congress had been entirely
undone。 Metternich and Alexander and Talleyrand had tried
to give the people of Europe a lasting peace。 The methods
they had employed had caused endless wars and revolutions and
the feeling of a common brotherhood of the eighteenth century
was followed by an era of exaggerated nationalism which has
not yet come to an end。
THE AGE OF THE ENGINE
BUT WHILE THE PEOPLE OF EUROPE WERE
FIGHTING FOR THEIR NATIONAL
INDEPENDENCE�察�THE WORLD IN WHICH THEY
LIVED HAD BEEN ENTIRELY CHANGED
BY A SERIES OF INVENTIONS�察�WHICH HAD
MADE THE CLUMSY OLD STEAM ENGINE
OF THE 18TH CENTURY THE MOST FAITHFUL
AND EFFICIENT SLAVE OF MAN
THE greatest benefactor of the human race died more than
half a million years ago。 He was a hairy creature with a low
brow and sunken eyes�察�a heavy jaw and strong tiger´like teeth。
He would not have looked well in a gathering of modern scientists��
but they would have honoured him as their master。 For
he had used a stone to break a nut and a stick to lift up a heavy
boulder。 He was the inventor of the hammer and the lever�察�our
first tools�察�and he did more than any human being who came
after him to give man his enormous advantage over the other
animals with whom he shares this planet。
Ever since�察�man has tried to make his life easier by the use
of a greater number of tools。 The first wheel ��a round disc
made out of an old tree�� created as much stir in the communities
of 100��000 B。C。 as the flying machine did only a few years
ago。
In Washington�察�the story is told of a director of the Patent
Office who in the early thirties of the last century suggested
that the Patent Office be abolished�察�because ``everything that
possibly could be invented had been invented。'' A similar
feeling must have spread through the prehistoric world when
the first sail was hoisted on a raft and the people were able
to move from place to place without rowing or punting or
pulling from the shore。
Indeed one of the most interesting chapters of history is
the effort of man to let some one else or something else do his
work for him�察�while he enjoyed his leisure�察�sitting in the sun
or painting pictures on rocks�察�or training young wolves and
little tigers to behave like peaceful domestic animals。
Of course in the very olden days�察�it was always possible
to enslave a weaker neighbour and force him to do the unpleasant
tasks of life。 One of the reasons why the Greeks and
Romans�察�who were quite as intelligent as we are�察�failed to
devise more interesting machinery�察�was to be found in the wide´
spread existence of slavery。 Why should a great mathematician
waste his time upon wires and pulleys and cogs and fill
the air with noise and smoke when he could go to the marketplace
and buy all the slaves he needed at a very small expense��
And during the middle´ages�察�although slavery had been
abolished and only a mild form of serfdom survived�察�the guilds
discouraged the idea of using machinery because they thought
this would throw a large number of their brethren out of
work。 Besides�察�the Middle´Ages were not at all interested
in producing large quantities of goods。 Their tailors and butchers
and carpenters worked for the immediate needs of the small
community in which they lived and had no desire to compete
with their neighbours�察�or to produce more than was strictly
necessary。
During the Renaissance�察�when the prejudices of the Church
against scientific investigations could no longer be enforced as
rigidly as before�察�a large number of men began to devote their
lives to mathematics and astronomy and physics and chemistry。
Two years before the beginning of the Thirty Years War��
John Napier�察�a Scotchman�察�had published his little book which
described the new invention of logarithms。 During the war it´
self�察�Gottfried Leibnitz of Leipzig had perfected the system of
infinitesimal calculus。 Eight years before the peace of Westphalia��
Newton�察�the great English natural philosopher�察�was
born�察�and in that same year Galileo�察�the Italian astronomer��
died。 Meanwhile the Thirty Years War had destroyed the prosperity
of central Europe and there was a sudden but very general
interest in ``alchemy��'' the strange pseudo´science of the
middle´ages by which people hoped to turn base metals into
gold。 This proved to be impossible but the alchemists in their
laboratories stumbled upon many new ideas and greatly helped
the work of the chemists who were their successors。
The work of all these men provided the world with a solid
scientific foundation upon which it was possible to build even
the most complicated of engines�察�and a number of practical
men made good use of it。 The Middle´Ages had used wood for
the few bits of necessary machinery。 But wood wore out
easily。 Iron was a much better material but iron was scarce
except in England。 In England therefore most of the smelting
was done。 To smelt iron�察�huge fires were needed。 In the
beginning�察�these fires had been made of wood�察�but gradually
the forests had been used up。 Then ``stone coal'' ��the petrified
trees of prehistoric times�� was used。 But coal as you
know has to be dug out of the ground and it has to be transported
to the smelting ovens and the mines have to be kept
dry from the ever invading waters。
These were two problems which had to be solved at once。
For the time being�察�horses could still be used to haul the coal´
wagons�察�but the pumping question demanded the application
of special machinery。 Several inventors were busy trying to
solve the difficulty。 They all knew that steam would have to
be used in their new engine。 The idea of the steam engine was
very old。 Hero of Alexandria�察�who lived in the first century
before Christ�察�has described to us several bits of machinery
which were driven by steam。 The people of the Renaissance
had played with the notion of steam´driven war chariots。 The
Marquis of Worcester�察�a contemporary of Newton�察�in his book
of inventions�察�tells of a steam engine。 A little later�察�in the year
1698�察�Thomas Savery of London applied for a patent for a
pumping engine。 At the same time�察�a Hollander�察�Christian
Huygens�察�was trying to perfect an engine in which gun´powder
was used to cause regular explosions in much the same way as
we use gasoline in our motors。
All over Europe�察�people were busy with the idea。 Denis
Papin�察�a Frenchman�察�friend and assistant of Huygens�察�was
making experiments with steam engines in several countries。
He invented a little wagon that was driven by steam�察�and a
paddle´wheel boat。 But when he tried to take a trip in his
vessel�察�it was confiscated by the authorities on a complaint of
the boatmen's u
