CHAPTER XII

THE TRAVEL OF TO-MORROW

The travel of to-morrow! It is a fascinating subject, for, as we

look backward through the last century and see the marvellous

progress that has been made, it is impossible to believe that now

we have come to a standstill. How then shall we travel in the

future? Will it be in some new form of railway train or motor-car,

with increased speed and added comfort? Or shall we leave solid

earth behind us altogether and make our journeys in great airships

and aeroplanes?

We will begin with the more commonplace methods, and consider the

possibilities of improvements and innovations in railway travel.

Lately a great deal has been said and written about the mono-rail,

and it seems quite likely that alterations will take place in

this direction, for a single-line railway is comparatively cheap

to construct, and has many other advantages, among them that of

greatly increased speed. It is estimated that this could easily

reach two miles a minute.

In Africa we saw a very primitive form of mono-railway, and there

is another in Algeria, where the trucks or baskets filled with

agricultural produce hang on either side of a single line and are

drawn along by mules.

A real mono-railway with engines, railway carriages, and trucks is

already in existence in Ireland, where it runs between Listowel

and Ballybunion. The line is raised some feet from the ground, and

is about 10 miles in length. The engine is a very curious-looking

machine, with a boiler on each side and two funnels. This is

arranged so that the weight is evenly balanced. There are also

methods by which the trains on a mono-railway may be steadied by

means of a wonderful contrivance called a gyroscope.

Closely allied to the single-line railway is the hanging railway,

which was first invented to carry loads of merchandise or minerals

across rivers or over rough forest lands where an ordinary line

would be difficult and expensive to construct. There is one of

these hanging railways in Rhodesia, where a strong wire crosses

from bank to bank of a river, and carries a chair-shaped seat which

can hold two passengers. This is dragged backwards and forwards by

means of a second wire.

[Illustration: MONO-RAIL CAR, WITH GYROSCOPE.]

Sometimes, instead of wire, rope is used, and these rope railways

can be seen in use at many of the mines in South Africa.

Other and more elaborate railways in the air have been made in

Germany, and there is one for passengers running between Barmen

and Elberfield. In this case the single rail is raised on high

trestles, and the carriage, which looks very much like a large

tramcar, runs along the line suspended beneath the trestles.

Then, too, we may in the future have railways that will take us

across the English Channel, either through a great tunnel or over a

bridge, reaching, as was proposed in 1884, from Folkestone to Cape

Grisnez.

A third plan that has been suggested for crossing to France is

that of a submarine bridge, upon which a curious construction or

platform would run, and on this the trains themselves could be

taken from shore to shore, while still another proposal was that

large ferry-steamers should be built, on the lower decks of which

the trains could be carried.

And now we will leave the earth and look at the pictures of

airships and the wonderful aeroplanes, which, although improvements

are being made every day, can already travel at an almost

incredible speed and with a security that only a little while ago

would have been considered quite impossible. Nowadays air travel

is not only a possibility but an accomplished fact, and it is hard

to realise that it has come about during the last twenty years, and

that before then practical flying machines were unknown.

[Illustration: OVERHEAD TROLLEY.]

From very early times, however, inventors and scientists have

dreamed and experimented, and no less than seven hundred years ago,

Roger Bacon, one of the most learned men of his day, seems to have

looked down through the centuries and to have actually seen the

aeroplanes with which we are now familiar.

"There may be made a flying instrument," he says, "so that a man

sitting in the midst of the instrument and turning some mechanism

may move some artificial wings so that they may beat the air like a

bird in flight."

It was a strange prophecy, but in those far-off times--the dark

ages we call them--men had already fixed their hopes on flight, and

school children were trained in the use of wings as in that of the

globes.

We are not told what advantages this curious accomplishment gave to

the little boys and girls of the thirteenth century, and, indeed,

it may have brought them ill-fortune, for in those days inventors

were often accused of witchcraft, and new ideas were looked upon

with suspicion. Even centuries later, when the first balloons

were causing great excitement in England, many people thought that

it was wrong to spurn the laws of nature by attempting to fly.

[Illustration: MONOPLANE, THE FIRST TYPE TO CROSS THE CHANNEL.]

During the seventeenth and eighteenth centuries some very strange

flying machines were made, and even before that time, in the reign

of James IV. of Scotland, we find that "The Abbot of Tungland tuik

in hand to flie with wingis." The bold Churchman, however, did not

succeed in his rash venture, but fell from the wall of Stirling

Castle and broke his thigh.

In 1709 another monk planned a wonderful flying ship which was to

carry twelve men besides stores of food, and about sixty years

later a Frenchman made himself "A whirl of feathers, curiously

interlaced and extending gradually at suitable distances in a

horizontal direction from his head to his feet." In this eccentric

costume the would-be bird-man fluttered down from a height of

seventy feet and escaped uninjured.

[Illustration: WATERPLANE, BIPLANE, AND SCOUT BALLOON.]

The makers of balloons, meanwhile, met with more success, and

they bravely experimented with their frail contrivances, which

at first were filled with heated air and necessitated a fire

in the basket-work car, fed with fuel of chopped straw. As may

be imagined, many accidents occurred, but the inventors went

on their way undaunted, and in the middle of the nineteenth

century we find a man named Nadar constructing an enormous balloon

called the "Giant," which seems to have been the forerunner of

the great airships of to-day. This monster would, we hear, have

exactly fitted into the dome of St. Paul's Cathedral. It had a

smaller balloon attached to it, and below both a car fitted with

wheels. This was divided into compartments for the captain and the

passengers, with beds, baggage, and provisions, while a printing

office and a photographer's room were included.

Nadar's ambitions, however, did not stop at this marvel. Indeed,

the "Giant" was only intended to be a means of raising funds for

the making of a flying machine, which was to be called the aeronef

and have wings and a screw propeller.

The difficulty then, and for many years afterwards, was to make an

engine which at the same time should be sufficiently strong and

yet light. It was not until another fifty years had passed that

this problem was solved and then we find the modern aeroplanes and

hydroplanes being gradually developed and improved.

In 1909 a French aviator crossed the Channel for the first time,

and since then the progress has been extraordinary, so that now

we think little of feats which a dozen years ago would have been

considered quite outside the bounds of possibility.

Side by side with the aeroplanes, dirigible balloons have been

developed, and we can hardly doubt that in the future this mode of

travel will come to be as safe and almost as commonplace as our

railways and motor-cars of to-day.
