At the gatehouse of Summerfield Hospital in Western Road, off Dudley
Road, I set the Time Machine for 1775. When I pressed the GO button
the scene changed completely, and I found myself on a bare heath
with few trees in sight.
There were some cottages around a green away to the west, and beside
me a postmill's sails were turning and creaking busily in the strong
wind.
It was a blustery morning in late spring. Not far away a burly
red-faced man was using a simple sighting instrument on a tripod
and scrawling in a notebook while his horse cropped the sparse grass.
Another rider came up and dismounted. Having seen portraits of
both men, I knew that the surveyor was James Brindley, the great
canal engineer, and that the kindly, jovial newcomer was Matthew
Boulton the manufacturer, whose Soho Works lay just across Hockley
Brook, half a mile to the north.
Boulton: Well met, Mr. Brindley ! I expected to find you in our
neighbourhood today. You will recall me, I think ? Boulton of Soho
Hall.
Brindley: Indeed I do, Mr. Boulton. I could hardly forget you since
you were one of the gentlemen who hired me to make this survey for
a canal. Does your coming here show your impatience for me to complete
my task ?
Boulton: It does not, sir. I care too much for good workmanship
to hurry a skilled man. The fact is that I have a personal interest
in your plans in this part of the parish of Birmingham. You know
that my manufactory lies in the valley yonder ?
Brindley: That I do, sir. When this survey is finished, I hope
to visit it, with your permission.
Boulton: And so you shall. I welcome visitors, so long as they
do not try to entice away my workmen or copy my devices! People
come from far and wide to see the machines at work and to exclaim
at the variety and quality of the wares we produce. Well now, I
have long known that a canal can do for Birmingham. It can bring
coal and iron cheaply from the Staffordshire mines, and so reduce
the cost of our manufactures; and when it is linked to the others
you are building, it will give us a waterway for our wares from
the middle of the town to the sea! But when I joined the other gentlemen
in these schemes I was thinking of my own advantage as well as Birmingham's.
Brindley: Indeed, sir? If you are thinking, as I believe, that
my canal will pass beside your works, then I must tell you that
it will not. The route that I propose to follow goes here, across
the heath. It is necessary to keep the canal on one level as far
as can be: and though this way will oblige me to make several great
loops round valley heads, yet will it be more quickly made and cheaper
than if I took it down into valleys and out again by means of locks.
True, the navigation will be somewhat longer, but the loops will
bring more places closer to it!
Boulton: But tell me, could you not cut a branch or arm from near
this place to Soho?
Brindley: Your Works is right in the valley, is it not?
Boulton: Yes, on the Handsworth side of Hockley Brook, whose water
turns my wheels - when there is enough!
Brindley: Then, Mr. Boulton, I must explain that my problem is
also lack of water. The streams hereabout are small, and the supply
I can take from them will be hardly enough to fill the canal and
keep it filled, for at all times, but especially in hot weather,
there will be a loss of water by evaporation. I shall make a reservoir
on the Winson Green Brook to store water, and another at Smethwick
to supply my top level, but there will be nothing to spare. If I
built you a branch canal right down to Soho Works, several locks
would be needed. They would cost you a large sum, which perhaps
you could afford, but they would cost me a lockful of water every
time a boat went up or down, which my canal could not spare. So,
sir, I cannot do it.
Boulton: Yes, I see, but there would be no difficulty in making
an arm that would be on the same level as the main canal, as far
as the valley edge on this side ?
Brindley: None at all, sir.
Boulton: Then, Mr. Brindley, as soon as your Birmingham Canal Navigation
is completed - perhaps even before - I shall employ you to build
me the Soho Branch Canal and even if my wares must be trundled in
carts to reach the wharf, I shall know that for the rest of their
journey they will travel much more safely than they do now, jogging
in packhorse baskets along these abominable turnpikes. At present,
pack them as I will, my most delicate wares are often damaged.
Brindley: Ah, sir, canals will do much for Birmingham! One narrow
boat, pulled by one horse, can carry as much as 300 packhorses,
no more slowly and so much more cheaply, despite the cost of building
the canal. If my plans are carried out, in a few years' time the
Thames, the Mersey, the Humber and the Severn will all be joined
by a Silver Cross of canals. Birmingham will be near the centre
of that Cross, with a way by water to all the seas.
Boulton: I think you know, Mr. Brindley, that I - and Birmingham
- have two great problems, two great lacks. They are want of power
and of good communications. Your canals will give us the second,
but we shall still lack power. When my pool runs dry I have to use
horses to turn my machinery, and my fellow manufacturers in the
town are always troubled by their lack of any sources of power than
muscle, wind and water. I have been experimenting with Savery steam
engine, in the hope that it would solve my problem, but have had
little success with it. My idea is that if I could pump water from
the lower pool back to the upper, my wheels need never stop. But
the engine consumes vast quantities of coal. What I need is a much
better engine. My friend Doctor Roebuck writes to me from Scotland,
that he is helping with money a young man, one James Watt. He has
invented a device that will make steam engines much more efficient
and cheaper to run. Mr. Watt and I must meet : I think we could
work together, he and I, making engines for use at watermills like
mine, for pumping out mines, and perhaps even for working machines
directly.
Brindley: Such an engine could solve my problem too, at the summit.
I had hoped to tunnel through the high ground at Smethwick, so as
to keep the canal level from Birmingham to Wednesbury. But the difficulties
are too great, so I must go over the top. I fear that the drain
of water will be too great for the small Thimblemill Brook to replace.
But if water that has gone down through the locks could be pumped
back up for use again there would be no loss and no delay to boats.
Boulton: Then we must both wish success to young Mr. Watt! Meanwhile
you and I both have work to do - I must return to my machines, and
you must complete your survey. You may count on my approval of your
plans when you present them to the Birmingham Canal Navigation Company,
Mr. Brindley. Good day to you - may the day when the first boat-load
of Wednesbury coal arrives in Birmingham be soon. The whole town
looks forward to it - what rejoicing there will be!
