A tribute to Eileen Caddy

Jonathan Dawson pays tribute to Findhorn co-founder Eileen Caddy who has died aged 89

This week saw the death of Eileen Caddy, one of the co-founders of the Findhorn community, at the age of 89. Eileen has been a treasure and a huge source of inspiration to the community.

The last of the many gifts that she gave was the clear instruction that her passing be a cause for thanksgiving rather than mourning and, true to her wish, the community seems almost to have an extra skip in its step this week.

So many glorious stories surround Eileen and the other early pioneers who were involved in the creation of this settlement back in the early 1960s. Most centre around her unwavering obedience to the guidance she received from the inner source that she called ‘the God Within’.

This guidance ranged from the bizarre (‘Build a community centre that can seat 200 people’ at a time when there was neither money in the bank nor any plans to create a community as such) to the unexpected (‘if the caravan you are sharing with six others is too noisy, go meditate in the public toilets’ – she did, for years) to the many gems of wisdom on achieving stillness and connecting with inner divinity that were later collected into the book ‘Opening Doors Within’.

Whether it made obvious sense or not, Eileen’s guidance was the compass by which the emerging community steered.

The key moment in defining the nature of the community came in 1971 when Eileen returned from a meditation with the guidance that it was now up to members to get their own guidance – no longer would she be the sole source of authority. This mirrors a tricky moment in the evolution of many intentional communities: how to stage the transition from the founders to the next generation?

This is all the more difficult in cases like Findhorn, where the authority of the first, founding generation is recognized as being divinely inspired. Eileen’s guidance ensured the transition to a mature community that had to find the wisdom and inspiration to make its own decisions.

Guidance remains at the heart of our decision-making structures to this day. So, meetings tend to begin and end with periods of silence and are often punctuated with short meditations. For sure, there is no guarantee that peoples’ guidance will always coincide – make of that what you will! However, the attempt to gain access to deeper sources of wisdom is surely laudable, on the premise alone that the intelligence potentially available to us is not limited to the rational mind.

Take, for example, the new piece of land just to the south of the built settlement that is coming up for development, called Duneland. We could limit our process around this to rational discussions involving planners and architects. What we have chosen to do is to walk the boundaries of the land singing, to sit in the land getting to know its moods and shapes more intimately, to seek to create a silence in which the spirit of the land and of the other creatures that share it can communicate with us.

This is not just more fun than heady discussions in darkened rooms – though we are no strangers to these too! – but is also capable of opening us up to wisdom that can only accessed in stillness; we are ever seeking ways of listening more deeply to the vibrations of the web in which we are but one thread.

This is the legacy that Eileen and her co-founders have left to us. For this, and so much else, thank you.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
