Reunion of Descendants of the First Ten Settlers of Bathurst

In 2015 Bathurst, NSW, celebrated its 200th anniversary. The ‘Bathurst 200’ website is no longer available but it seems to have been archived by the Wayback Machine and the National Library of Australia.

On 10 May 2015 Callum and I attended an event in Bathurst that was part of the  anniversary. We drove up the day before and stayed at the Quality Hotel, Bathurst. That night we walked around the city centre and had a look at the light-show and the displays prepared for the event, including one for our ancestor, Richard Mills (c1780-1850).

On the following morning we had a look at the house built by Richard Mills around 1820. It is at 7 Lee Street Kelso and is now occupied by the Rural Fire Service and formally an Evans Shire Council building. Then we went to the Bicentennial Park heritage wall for the unveiling of a plaque. Then to Cheshire Barn, 8 Gilmour Street for a picnic and talks. After than Callum and I went to have a look at Holy Trinity Church which is where Richard Mills was buried.

The reunion was covered by the local newspaper. And here are some of our photos.

I kept a copy of the programme.

The Geography of our travels around Germany

In 2012 we went on a 10-week family holiday around Europe. We had been thinking about it for a few years and everything came together nicely in the summer of 2012. Barbara’s 30-year high-school reunion was taking place in her hometown in south-western Germany. This gave us some definite dates and places to plan around. We also wanted to see family in other parts of Germany, and friends in Austria and France. Over a few months we worked out a travel plan that used a combination of plane-flights and driving, to criss-cross Europe. At times it felt like we were working on a solution to the travelling salesman problem.

We were very aware that the boys would be missing a number of weeks of school. Understandably their teachers were not happy about this and we needed to make the case that the trip would be educational as well as valuable in the vague, personal sense. So we made a conscious effort to discuss with the boys the history and geography of the places we visited. We tend to discuss things with them anyway so really we were just trying to make the most of a wonderful trip.

A theme that soon became obvious was the river Danube.  Many of the places we were visiting were either on, or close to, the Danube. The Danube flows through many countries but for this trip we would only see it as far downstream as Vienna. In German it is ‘the Donau’, so I’ll use that name from now on. I’ll mention the places we visited, not in chronological order, but according to the river’s flow, starting with its source.

I suspect the source of any great river is a point of contention. The river-head might be made up of many tiny tributaries so it may not be easy to identify a single source. Hydrologists have rules for determining which tributary is the more major but this might change over time. And speaking of time, it may be that a particular location is regarded as the source for historical reasons. To point out that, say, the Romans regarded a place as the source does carry some historical authority. That is the case with the Donauquelle in the Black Forest town of Donaueschingen. You get an idea of the claim being made by the name of the town. The Donau has two main tributaries: the Brigach and the Breg, but the confluence was originally surrounded by swampy areas.

Here we are at the spring that is supposedly the source. The Roman Emperor Tiberius and various German Emperors came here for a look so maybe it’s true. The spring is now next to (and somewhat below) St John’s church. On the afternoon of our visit the parishioners had held a light lunch to raise funds for church repairs and we were happy to help them eat the left-overs.

Donaueschingen has an elevation of about 680m above sea level. The sign above points out that the mouth of the Donau, at the Black Sea, is some 2840km away. So water really doesn’t need much of a gradient to form a substantial river. (Note: the source of the two tributaries are somewhat higher at about 1000m). The Donau flows generally eastward across southern Germany, through northern Austria, along the border of Slovakia and Hungary, then south through Hungary and Serbia and finally turning east again forming the border between Bulgaria and Romania. It empties into the Black Sea via an extensive delta. The river is often divided into three sections: upper, middle and lower. The upper section ends when the river leaves Austria, so all the places we visited are part of this section.

Rohrach

The Rohrach at Geislingen flows into the Eyb which flows into the Fils which flows into the Neckar at Plochingen, which flows into the Rhine at Mannheim.

Donaueschingen is in the east of the Black Forest. Rain falling on the eastern side of the Black Forest tends to flow into the Donau while rain on the western side ends up in the Rhine (via the Neckar River). However, the hydrology is actually more complex than this suggests. Much of the state of Baden-Württemberg lies on a limestone plateau. The limestone has leached-away forming underground caverns and streams. These underground streams often flow towards the Rhine because it is lower than the Donau. The upshot is that although the Donau appears to have a substantial catchment in this area, in practice much of it does not contribute directly to the Donau. Instead a great deal of the flow is gained from substantial downstream tributaries.

In addition, the source of the Neckar is at Villingen-Schwenningen which is not that far from Donaueschingen! So when traveling around the Black Forest it is hard to know which rain-shower will end up in the Atlantic via the Rhine and which will find itself in the Black Sea via the Donau.

Barbara grew up in Geislingen an der Steige, which is east of the Black Forest. It is not far from Ulm, which in on the Donau. However, Geislingen is on the River Fils, which is a tributary of and flows westward to the Neckar, which, in-turn, flows through Stuttgart and then to the Rhine. Meanwhile at Ulm the Donau flowing northeast.

Geislinger Steige

An explanation is that between Geislingen and Ulm the Swabian Jura rises some hundreds of metres. This low mountain range has provided a barrier to movement and trade between the Neckar and the Donau since before Roman times. The steep climb between Geislingen and Amstetten is called the Geislinger Steige. The B10 road climbs this hill as does a very steep section of the main Stuttgart to Munich railway line.

Whenever in Geislingen we visit the ruins of Burg Helfenstein which overlooks the whole area including the train-line climbing the steige. We have photos taken over decades similar to the one taken on the 2012 trip.

Cuckoo Bees

Last week I was in the living room when a loud, buzzing insect flew past me. I’d left a door open so I wasn’t too surprised. From the flash of blue I thought it might be a big blow-fly. I followed it into the kitchen and was able to get a close view as it buzzed against the window. It was clearly no fly but looked more like a big, dark native bee and had distinctive blue spots on its abdomen. I took a few photos, to help with identification, and then opened the kitchen window to let him go on his way.

The photos are not very good – he was keen to escape and not at all interested in posing nicely for me. But they are good enough for identification.

Drain valve for Astralpool ZX cartridge filter

I needed to rearrange the pump and filter setup of our above ground pool. The only problem with the new arrangement is that the drain-hole for the filter (Astralpool ZX100) points towards the pool wall instead of away from it. This side of the pool is on the shady side, and takes a long time to dry out, so I don’t want that area getting wet unnecessarily. So I investigated the possibility of replacing the drain plug with some kind of valve or tap, so I could drain the water away through a hose.

Astralpool ZX cartridge filter

The drain plug has two threaded sections and can be removed completely if unscrewed carefully. At first I thought the plug was anchored inside the filter housing so that the plug wouldn’t come free and get lost. But the ‘anchor’ is just a second threaded section. Be careful unscrewing or re-screwing the plug – it would be easy to cross-thread it.

It was difficult to find a suitable valve to replace the plug. The plug appeared to have a 1/4″ BSP thread. (But a lot of pool equipment is designed in or for the USA so there was a real possibility the thread was actually the US equivalent: NPT). This is pretty small so I was looking for a tiny valve. I wandered around Bunnings for some time without much success. I was looking for 1/4″ BSP male on one end and a barb on the other to attach a piece of hose. Actually at first I had many possibilities in mind, including some sort of bulkhead fitting for the inside of the filter case and a female threaded valve outside. I also thought of using a home brew kettle valve but they are expensive.

I couldn’t find what I wanted so I searched ebay and eventually found a 1/4″ BSP to barb brass ball valve. It was only $3 including postage from China. Designed for use in either pneumatic or hydraulic systems it should be able to handle 12-15 psi of slightly salty water.  It took a while to arrive from China but it fits perfectly. I thought I may need to use some teflon tape on the threads but so far the rubber o-ring from the plug is making a water-tight seal.
