exploitation of steam. To electricity also, in spite of its

provocative nearness all about him, mankind had been utterly

blind for incalculable ages. Could anything be more emphatic than

the appeal of electricity for attention? It thundered at man's

ears, it signalled to him in blinding flashes, occasionally it

killed him, and he could not see it as a thing that concerned him

enough to merit study. It came into the house with the cat on any

dry day and crackled insinuatingly whenever he stroked her fur.

It rotted his metals when he put them together… There is no

single record that any one questioned why the cat's fur crackles

or why hair is so unruly to brush on a frosty day, before the

sixteenth century. For endless years man seems to have done his

very successful best not to think about it at all; until this new

spirit of the Seeker turned itself to these things.

How often things must have been seen and dismissed as

unimportant, before the speculative eye and the moment of vision

came! It was Gilbert, Queen Elizabeth's court physician, who

first puzzled his brains with rubbed amber and bits of glass and

silk and shellac, and so began the quickening of the human mind

to the existence of this universal presence. And even then the

science of electricity remained a mere little group of curious

facts for nearly two hundred years, connected perhaps with

magnetism-a mere guess that-perhaps with the lightning. Frogs'

legs must have hung by copper hooks from iron railings and

twitched upon countless occasions before Galvani saw them.

Except for the lightning conductor, it was 250 years after

Gilbert before electricity stepped out of the cabinet of

scientific curiosities into the life of the common man… Then

suddenly, in the half-century between 1880 and 1930, it ousted

the steam-engine and took over traction, it ousted every other

form of household heating, abolished distance with the perfected

wireless telephone and the telephotograph…

Section 6

And there was an extraordinary mental resistance to discovery and

invention for at least a hundred years after the scientific

revolution had begun. Each new thing made its way into practice

against a scepticism that amounted at times to hostility. One

writer upon these subjects gives a funny little domestic

conversation that happened, he says, in the year 1898, within ten

years, that is to say, of the time when the first aviators were

fairly on the wing. He tells us how he sat at his desk in his

study and conversed with his little boy.

His little boy was in profound trouble. He felt he had to speak

very seriously to his father, and as he was a kindly little boy

he did not want to do it too harshly.

This is what happened.

'I wish, Daddy,' he said, coming to his point, 'that you wouldn't

write all this stuff about flying. The chaps rot me.'

'Yes!' said his father.

'And old Broomie, the Head I mean, he rots me. Everybody rots

me.'

'But there is going to be flying-quite soon.'

The little boy was too well bred to say what he thought of that.

'Anyhow,' he said, 'I wish you wouldn't write about it.'

'You'll fly-lots of times-before you die,' the father assured

him.

The little boy looked unhappy.

The father hesitated. Then he opened a drawer and took out a

blurred and under-developed photograph. 'Come and look at this,'

he said.

The little boy came round to him. The photograph showed a stream

and a meadow beyond, and some trees, and in the air a black,

pencil-like object with flat wings on either side of it. It was

the first record of the first apparatus heavier than air that

ever maintained itself in the air by mechanical force. Across the

margin was written: 'Here we go up, up, up-from S. P. Langley,

Smithsonian Institution, Washington.'

The father watched the effect of this reassuring document upon

his son. 'Well?' he said.

'That,' said the schoolboy, after reflection, 'is only a model.'

'Model to-day, man to-morrow.'

The boy seemed divided in his allegiance. Then he decided for

what he believed quite firmly to be omniscience. 'But old

Broomie,' he said, 'he told all the boys in his class only

yesterday, "no man will ever fly." No one, he says, who has ever

shot grouse or pheasants on the wing would ever believe anything

of the sort…'

Yet that boy lived to fly across the Atlantic and edit his

father's reminiscences.

Section 7

At the close of the nineteenth century as a multitude of passages

in the literature of that time witness, it was thought that the

fact that man had at last had successful and profitable dealings

with the steam that scalded him and the electricity that flashed

and banged about the sky at him, was an amazing and perhaps a

culminating exercise of his intelligence and his intellectual

courage. The air of 'Nunc Dimittis' sounds in same of these

writings. 'The great things are discovered,' wrote Gerald Brown

in his summary of the nineteenth century. 'For us there remains

little but the working out of detail.' The spirit of the seeker

was still rare in the world; education was unskilled,

unstimulating, scholarly, and but little valued, and few people

even then could have realised that Science was still but the

flimsiest of trial sketches and discovery scarcely beginning. No

one seems to have been afraid of science and its possibilities.

Yet now where there had been but a score or so of seekers, there

were many thousands, and for one needle of speculation that had

been probing the curtain of appearances in 1800, there were now

hundreds. And already Chemistry, which had been content with her

atoms and molecules for the better part of a century, was

preparing herself for that vast next stride that was to

revolutionise the whole life of man from top to bottom.

One realises how crude was the science of that time when one

considers the case of the composition of air. This was

determined by that strange genius and recluse, that man of

mystery, that disembowelled intelligence, Henry Cavendish,

towards the end of the eighteenth century. So far as he was

concerned the work was admirably done. He separated all the known

ingredients of the air with a precision altogether remarkable; he

even put it upon record that he had some doubt about the purity

of the nitrogen. For more than a hundred years his determination

was repeated by chemists all the world over, his apparatus was

treasured in London, he became, as they used to say, 'classic,'

and always, at every one of the innumerable repetitions of his

experiment, that sly element argon was hiding among the nitrogen

(and with a little helium and traces of other substances, and

indeed all the hints that might have led to the new departures of

the twentieth-century chemistry), and every time it slipped

unobserved through the professorial fingers that repeated his
