Thames Head, they’ve called these meadows since
time immemorial. Here, they say, the river is born, in dandelion carpets
beneath a broad Cotswold sky.
Folk reckoning was buttressed over
the centuries by journalists’ and travellers’ articles, scholarly opinion, and
eventually by formal recognition from the Ordnance Survey and Thames Conservancy.
On account of the last a marker stone now stands in these fields,
officially recognising its base as the source of the River Thames.
But is it?

One of the river’s many
headwater channels runs through the village of Ashton Keynes. It claims this
channel as the true river. But who can say for sure? |

Cricklade’s North Meadow,
putting on its annual display of snake’s head fritillaries. |
Above Cricklade the river breaks into
a maze of headwaters and ceases to exist in the singular. These waterways’ differences
in length, depth and flow are trivial now, and they come and go with the
seasons, making any attempt to designate one or another as the true or main
Thames arbitrary. However, if you follow one of these channels –
officially a tributary, the Churn – you will come to a spot further north called Seven Springs, where a different marker stone, backed
up by a notice from the local council, identifies that site, ‘despite the
controversy over the years’, as the ultimate source of the river.
There’s a problem here. It’s a
sensitive one. This is the English’s principal river. It's fed and watered them, inspired them, flooded them, borne them in and out on their migrations, their trades, their
wars, their nation-building dreams, their industrial and imperial madnesses – but where,
in the first place, does it come from?
Clearly this dispute had all the
ingredients for violent upheaval across these restive western provinces, and in
1937 it made it into parliament. The representative for Stroud, a Mr. Perkins,
whose constituency included Seven Springs, insisted to the Agriculture Minister
that Seven Springs was in fact the ‘correct’ source on the grounds that it was
fourteen miles further from the estuary than Thames Head, as well as twice its
height above sea level. The next Ordnance Survey map, he argued, would do
well to mark it accordingly.
This would indeed have reflected
established geographic practice for reckoning a river’s source, while not
incidentally making the Thames longer than the Severn. But the pertinent fact
wasn’t one of distances or elevations. Rather it was that Mr. Morrison, the
Agriculture Minister, just happened to be the MP for Cirencester whose
territory included Thames Head. And so he replied: ‘I understand that it is not
an invariable rule...to regard as the source...the source of the tributary
most distant from its estuary’. Further challenged, to laughter, that Thames Head also periodically dries up (likewise true), he simply shut the matter down: ‘I
am aware of these considerations, but they do not alter my view, as confirmed,
that the River Thames rises in my constituency and not in that of my honourable
friend.’
As so often in this world, it seems the
question of the source is a question not of truth, but of power.

In that connection, let the
statement of this field and sky offer some strength, however small, to whoever
needs it right now. |
What says the river itself?
Well, the reality of rivers is that
they don’t gush from a single point. They accumulate, diverse and
disparate, all the way down their drainage basins. For a few seconds you
are a source too, whenever in the course of a walk like this you spill your
flask or pee in the bushes. Then it flows into the sea, rises as cloud, and
falls as rain to begin the journey all over again.
In which case, perhaps the
nineteenth-century scientist Thomas Huxley, in an 1869 geography lecture, put
it best:
Perhaps much else does too – but not this journey. 250
kilometres and two and a half years from the ‘cold, fog,
tempests, disease, exile and death’ of the estuary, as Marlow in Heart of
Darkness had it – and finding this still quite a fair description all the
way up – we attain the edge-of-the-world sunlit slopes where the water’s trail
is lost. And because this expedition (or perhaps thankfully, this text) has to end
somewhere, let it take as its destination, arbitrarily of course, the place
where centuries’ weight in custom marks, if not the One True Source, then the human
commemoration of those water molecules’ reunion, there and everywhere, into
that party which, in its journey together, has come to be known as the river –
the Dark River – the Thames.
