From the Netherlands to Australia

Having lived and worked in a country house, Bert and Ethne had a lot of things to pack. There was one extremely big item that needed a special 40-foot seatainer: the water barometer. It had been carefully dismantled before the removalist came to pick it up. The four glass pipes were packed in long wooden crates, and also the cistern was carefully packed in a special crate.

In December 1999 Bert and Ethne left the Netherlands. They stayed with one of Bert’s cousins in Bunbury, and rented a house. From there the first trip to Denmark was made in January 2000. Ethne had been in Denmark before. She had seen that beautiful town in 1997, and never had stopped talking about it. Bert and Ethne found their spot already the first day of their arrival in Denmark, and two months later the removalist stood at their doorstep.

Unfortunately there was no room to store the long barometer plank; so all barometer parts were kept on hold in Fremantle. Meanwhile Bert went to Denmark’s CEO to talk about the idea of making the barometer useful to the community. Pascoe Durtanovich saw the photos of the Barometer Museum and was enthusiastic about the monumental instrument from the first moment. The only problem was that Denmark didn’t have a public building high enough to house the 12 metres high barometer. Bert and Ethne didn’t mind to wait until an opportunity would turn up. By the end of 2000 some alterations had been made on their house, and from that moment on the long plank, the pipes etc. could be stored. In 2001 the removalist came down with the extraordinary load. The trailer was so big, that it could not reach the house. A truck was needed to let the plank travel its last 850 metres.

  
All care was taken to keep the vulnerable plank undamaged.

The ceiling of the garage was left open to give the plank and the long crates access to the attic above the house. When the ceiling was placed, a huge manhole was made to get the enormous plank down at a later stage.

  
A slippery cardboard pack of about 140 kilo is quite a burden when it has to go upstairs, especially on a warm day.

Later on, Bert discovered that one pipe had been damaged during transport. A blemish of the Dutch removalist who had ignored Bert’s exact instructions for how to pack the vulnerable gear. Even worse, the vacuum pump and a box full of vacuum hoses had grown legs and were missing. Unfortunately it had become too late to claim the damage. Moreover, the Denmark Shire was not interested at that stage, so Bert took the situation reluctantly for granted, and concentrated on other things.

The building process

It was in 2004 when Pascoe Durtanovich contacted Bert to see if he was still interested to part with his brainchild. There were plans for a new multi-functional Visitor Centre in which a tower could be built especially for the water barometer. At the first stage, Bert had been thinking of a permanent loan, but after some consideration he felt that it would be better to donate the instrument to the Shire of Denmark. One of the conditions is that the barometer should be considered as a monument, carrying the name of The Bert Bolle Barometer. Furthermore the tower should be dedicated to the water barometer and the history of weather instruments in general and access should be free for everybody.

In the middle of the tower, which measures 4 x 4 meters, a solid pedestal 50 cm high was planned to be the base of the water barometer. Bert had promised to take up the task of installing the barometer and guided the craftsmen where needed. He assisted the electrician in designing and setting up the relay cabinet, which makes the vacuum pump remove the air out of the top of the pipe every six minutes.

After the Denmark Council had adopted the plans for the new Visitor Centre, Bert Bolle checked all parts of the water barometer. He started to negotiate with the removalist in the Netherlands about a new pipe, and how to get it transported to Down Under. Bert found the manufacturer in Germany prepared to get one 3 metre pipe specially made, and purchased it. The removalist, feeling guilty about the damage during former transport, took care for free transport to Western Australia. Bert picked the huge 10 Kg glass pipe up in Perth. His car was just big enough to hold the long pipe. Meanwhile Bert had bought a present for Ethne, a fiberglass sheep, which hardly fitted in the car too and caused some hilarious moments! Eventually the vulnerable pipe arrived undamaged in Denmark.


The glas pipe made a long and eventful trip from Germany to Denmark.

The pump that had been stolen during the removal, was another major problem. But Bert still knew his sources in the Netherlands, and soon the Dutch branch of the worldwide operating German pump manufacturer Busch proved to be so generous to donate a reconditioned rotary vane vacuum pump. Bert sent the money for packing and postage of the 25 Kg machine which soon arrived in Denmark. Final hiccup was the top part of the pipe, i.e. the hood with a barb where a vacuum hose is connected to the barometer. Bert had a Pyrex glass hood left from the installation job in 1985. He sent the hood to his former glass blower in the Netherlands, who blew a barb on it for vacuum hose connection. Meanwhile Bert ordered a safety device for the vacuum system to prevent water from reaching the vulnerable pump. It was Bert’s wish to donate a complete working instrument.

The Ambassador's personal note in the Guest Book.

 

During its first year, almost 100,000 visitors came to the Denmark Visitor Centre to see the barometer. The average turnover in Denmark’s tourist industrie had more than doubled and the first three Guest Books in the Barometer Tower are full. Lots of visitors left their positive notes and some of them were people from the Netherlands, who had seen the barometer in the Dutsch Barometer Museum. They were surprised to see the instrument back on the other side of the world. Meanwhile the Dutch press paid extensive attention to the new Denmark drawcard, which proves that the water barometer is still well-known in Europe, although the Barometer Museum in Holland was closed ten years ago.

The Bert Bolle Barometer is a lively instrument, constantly ‘on the move’. A microprocessor regulates a vacuum pump, which is connected to the top end of the water barometer. At six minute intervals, the pump evacuates the air from the glass pipe, causing the more than 12 metre tall instrument to fill with 55 litres of water within one minute. Visitors are invited to climb the stairs and follow the water to the top, where it starts to boil spontaneously, although its temperature is only about 20 degrees! After a reading period of two minutes, air is admitted to the top area of the pipe. Within another two minutes all the water will be back in the cistern downstairs, after which the six minute pump cycle of The Bert Bolle Barometer will start again.

Bert and Ethne have enough items left from their Dutch museum to equip the whole Barometer Tower. These items have been given on loan. A collection of antique barometers covers the tower walls, and there are huge 4 x 6 foot paintings showing the old instruments and their inventors. There are also two showcases with fine antique weather instruments and old weather houses. These showcases have been put in the hall of the Visitor Centre, near the entrance of the tower. There are captions in big letters, which proved to be a success in the Barometer Museum in the Netherlands. Especially older eyes cannot cope with small sized text boards. No squinting for the guests in the Barometer Tower.

In the Barometer Tower several interesting physical experiments are on display, e.g. the Atmosphere Simulator in which highs and lows are created artificially. There is also a Bell Jar with vacuum experiments. Alongside the right wall are five showcases with various mercury barometers and thermometers.

When entering the tower, there is a so-called calibration cabinet on show on the left hand side. This 2.2 Metres tall steel cabinet is a unique item. It was built in 1905 for the department of the Royal Dutch Meteorological Institute near the harbour of Rotterdam, and was used to calibrate the barometers used on board ship.

In the same left front corner on the floor of the tower is a showcase to house the extremely accurate Vaisala digital barometer, one of the showpieces of the former Barometer Museum in Holland. It was acquired by Bert and Ethne Bolle in the early nineties. The instrument has been re-calibrated in the Vaisala headquarters in Finland, thanks to generous intervention of Vaisala Pty Ltd in Hawthorn Victoria. The instrument passed the severe accuracy tests with flying colours. It can be considered as one of the most accurate barometers in Western Australia. The Vaisala barometer will enable visitors to compare its reading with e.g. their own domestic aneroid barometer. Directions for adjustment will be given. The separate display for the barometric pressure was donated by Amalgamated Instrument Co Pty Ltd (AIC) Australia.

On the right tower wall, a so-called Dutch ‘Donderglas’ (‘thunder glass’) can be seen. This glass instrument is the size of a hand, and is filled with water and air. During the first half of the 17th century they were the only available weather forecasting instruments, as the first mercury barometers came on the market around 1660. The ‘donderglas’ was also used on board ship, as they were small and easy to use. Skippers were more dependent on the weather than anybody else, and it is not unlikely that skipper Francois Thijssen and commander Pieter Nuyts had a ‘donderglas’ on their ship ‘Het Gulden Zeepaerdt’ (The Golden Seahorse), when they were the first ones to map the coast line between Cape Leeuwin and Ceduna in 1627.

In the Reading Room atop the Tower is a large print of a 17th century engraving, depicting the famous experiment with the Magdeburg Hemispheres. Otto von Guericke (1602-1686), mayor of Magdeburg in Germany, had invented a vacuum pump in 1650. Guericke chose a really dramatic way to demonstrate the force of air pressure. He had a pair of large copper hemispheres made, precisely constructed so that their rims fitted tightly together. When the rims were sealed with grease and the air was pumped out, the resulting sphere contained the world’s first artificial vacuum. The hemispheres were held firmly together by the air pressure of the surrounding atmosphere with an enormous force. Guericke had arranged two teams of eight horses harnessed together to separate the two hemispheres, but no matter how hard they pulled, the horses could not pull them apart, until the vacuum finally was released by opening a valve. All that had been holding the hemispheres together was the pressure of the air surrounding them. The vacuum inside the globe meant there was no opposing pressure to balance this great outer force.

The importance for Denmark

Bert and Ethne Bolle are feeling blessed and grateful to live in the pristine area of Denmark, and they are happy to donate the water barometer to the Denmark community. The instrument brought them a lot of luck in the sense of massive publicity and many, many visitors in the 12 years they ran their barometer Museum in the Netherlands. School children and adults came to admire the water barometer they had heard about. In other words, that barometer had proved to be a lucky shot. Considering the experience from the past, Bert realizes that his brainchild will be good for Denmark too. The barometer will be a landmark in the Great Southern, and eventually might become a Western Australian icon. It will attract people from miles away, and it will make people stop, people who perhaps otherwise might just have passed the town on their way to Albany or to the Tree Top Walk. Now they will notice the barometer tower, inspect the Visitor Centre, and eventually they might pay a visit to the local shops, galleries, restaurants and the many other things that Denmark has to offer. Some of them will decide to stay longer and book accommodation. Those new tourists will bring business and employment into town, and will enable many hard working local business people to bridge the slow winter period. Besides all that, the water barometer is a non-religious and non-political item, as the weather is on its own independent level. The instrument is just beautiful, it is the largest glass artwork in Denmark and shows in a glorious way what can be done with wood and glass. It will remind the visitors how important the weather was for the old Denmark pioneers, whose lives were inextricably entwined with the weather, and how important it still is for people like farmers, wine growers, surfers and so forth.

Wood - Wine - Weather. Three important Ws for Denmark. Let’s go for it!
