Arms and locks

THE GRAND UNION canal, constructed from the late 1790s onwards, is an important artery of England’s canal network. Beginning at Brentford on the River Thames, it winds its way to Braunston and Birmingham. Along its way it meets other canals, some of which are designated ‘arms’. For example, the Paddington Arm joins the main canal at Bulls Bridge in west London and from there it makes its way eastwards to Paddington. Recently, we visited friends, who live in Northamptonshire, and they took us on a walk along another arm of the Grand Union, the Northampton Arm. This branch of the main canal begins near Gayton and Blisworth and runs to nearby Northampton, where it enters the River Nene, which flows eastwards towards The Wash, an enormous inlet of the North Sea.

A swing bridge with a lock behind it

Much of the Northampton Arm is very narrow, just wide enough for passage of a single narrow boat. At regular intervals, the arm widens to allow vessels travelling in opposite directions to pass each other. Though short in length, only 4.6 miles, the Northampton Arm has seventeen separate, hand-operated locks for vessels to negotiate. The twelve of these, a flight of locks, is 1123 yards from the Gayton junction with the main canal. These twelve locks are along a stretch of canal only nine tenths of a mile long. The northernmost lock, that nearest towards Northampton, is a few yards north of a bridge carrying the M1 motorway. The locks carry the water from a bit over 300 feet above sea level nearest Gayton down to less than about 225 feet, each lock capable of lifting or lowering a vessel over 6 feet on average. Nearer Gayton, there is an old swing bridge, rather like a castle’s drawbridge. Looking at old maps, it appears that there were several more of these along the arm, but we only spotted one in the stretch between Gayton and the M1.

The canal and its associated towpath pass beneath the motorway through a giant concrete arch, paraboloid in shape and reinforced with horizontal concrete beams. Lined with graffiti, both conventional and anarchic artwork, walking under the motorway is an eery, rather science fictional experience. In contrast to this brutalist concrete arch, several lovely brick, hump-backed bridges carry minor roads over the Arm

The authorisation of the Northampton Arm was given in 1793, but it took another 18 years before it was ready for use. A brief hstory of the Arm (https://waterways.org.uk/waterways/discover-the-waterways/grand-union-canal-northampton-arm) relates:

“Almost immediately the Arm began to carry a large volume of merchandise and stayed busy for over 100 years through to after the First World War.  In the post war years coal, grain and timber were supplemented by goods needed for the show industry such as strawboards for packing as well as iron ingots for castings.  After World War II the carriage of goods ceased as road competition strengthened.”

Now, the Arm is used by intrepid canal boat owners, who are not averse to too much manipulation of lock gates. On the sunny Saturday afternoon that we visited the lock flight, we only saw one narrow boat attempting to negotiate the flight of twelve locks. In contrast, at Gayton Junction, the main Grand Union Canal, from which the Arm branches off, was full of pleasure-seekers’ narrow boats and other craft.

Though hardly used for freight these days, the canal system provides much pleasure to visitors both afloat and on shore. Wandering along the towpaths, one cannot fail to be amazed when considering the engineering ingenuity of the canal builders that we can still see today, as well as the work that is done to keep these waterways usable so many years after they were constructed.

Calling the world

WHEN I WAS A CHILD, the family possessed a radio, which could receive long wave, medium wave, and short-wave signals. It was made by Pye, contained in a dark brown wooden cabinet, and took several minutes to ‘warm up’ before anything could be heard from it. It was faced with glass screen behind which there was a list of radio stations and a vertical cursor that could be moved across the list to tune into different stations. The stations listed were, to my young mind, quite exotic. They included places such as Berlin, Budapest, Beromunster, Moscow, Prague, Monte-Carlo, Leipzig, Hilversum, Vienna, Sofia, Cairo, and Luxembourg. One of the places on the tuning screen sounded far less exotic to me: Daventry. I knew that this place was somewhere in the English Midlands, and that gave it less appeal to me than places further afield and across the sea.

Recently, we spent a couple of nights near Rugby in Warwickshire. After leaving it to travel eastwards, we noticed that we would be passing through Daventry, and decided to stop there for breakfast. Prior to our arrival in that small town in Northamptonshire, I believed that it would turn out to be a place of little interest apart from the fact that I remembered having seen its name on our old radio back home in the early 1960s. How wrong I was to have pre-judged Daventry so harshly.

We parked next to a modern shopping centre, attractively arranged around an open space in which people were enjoying refreshments at outdoor tables and chairs. This contemporary shopping precinct is close to the High Street, which runs from Market Square to Tavern Lane. This thoroughfare is rich in historic buildings.

Overlooking Market Square is the former Daventry Moot Hall, an 18th century building, and beyond it on a slight elevation is the Holy Cross Church. This neo-classical style church was built between 1752 and 1758 to the design of David Hiorne (1715-1758) of Warwick. Not only does it resemble London’s St Martin-in-the-Fields, but on a smaller scale (and with a far smaller portico), but also many churches built by the British in India during the 18th and 19th centuries. Seeing the church in Daventry reminded me of the far larger St John’s Church in central Calcutta and the Danish church at Serampore on the River Hooghly. Unfortunately, the church in Daventry was not open when we visited it.

At the other end of the High Street, where it continues as the narrower Tavern Lane, there is a curious building with gothic revival features and crenellations. We asked an elderly man about the building and he told us that it used to be the BBC Club. It was then that I remembered that Daventry had connections with radio broadcasting. I recalled seeing the place’s name on our old radio at our home in northwest London. Our informant reminded us that for many years the transmitters near Daventry carried news and other broadcasts from Britain to the rest of the world.

On the 27th of July 1925 at 730 pm, the BBC began broadcasting from its new station at Daventry. At first, these transmissions could be received on crystal radio sets within a 250-mile radius of a circle with Daventry at its centre. Soon after this, broadcasts could be received far further afield. This was further augmented when the BBC installed much more powerful transmitters in about 1927. By the end of WW2, Daventry was transmitting the ‘highbrow’ Third Programme (now, ‘Radio 3’) broadcasts.

In December 1932, Daventry began transmitting programmes to a world-wide audience on the Empire Service. As the threat of war increased during the 1930s, Daventry started transmitting regional services such as The Arabic Service (in Arabic) and The Latin American Service (in Spanish). After WW2 broke out, there were broadcasts in many other foreign languages. Some monitoring of foreign broadcasts was also carried out in Daventry.

During the Cold War that followed the end of WW2, Daventry was involved in the transmission of programmes to people living on the Soviet side of the so-called Iron Curtain. Until its closure in 1992, the radio station and its transmitters at Daventry were continually updated. One of several reasons for its closure was the end of the Cold War following Gorbachev’s leadership of the USSR and the fall of the Berlin Wall.

Now, returning to the gothic revival building at the end of Daventry’s High Street, here is what Norman Tomalin, who worked at Daventry and has written a history of its radio station (www.bbceng.info/Books/dx-world/dx-world.htm), has to say about it:

“For the many thousands of BBC staff who briefly came to Daventry, the BBC Club … was home from home. It provided a central cosy meeting place, a break from the digs, a bar, billiards, table tennis, and photographic rooms and on the top floor, pride of place, a much treasured amateur radio transmitter. Call sign 5XX”

‘5XX’ was the call sign of the first transmitter at Daventry. It was superseded by another ‘5GB’ in 1927.

Our elderly informant told us that he remembered that broadcasts from his hometown used to begin with the words: “Daventry Calling The World”. In his book “Daventry Calling”, Tomalin wrote that the very first broadcast from Daventry began with the words: “Daventry Calling”, for back in 1927, it was not the world that could receive the programmes, only people in the UK.

I wonder how many of the people who listened to broadcasts from Daventry all over the world had any idea where the town was and if they did, did they wonder if it was as great a city as many of the others that appeared on radio tuning dials.
