Tanks!

Anyone in the office will tell you that I have a keen interest in military history, especially anything related to the World War 2 period. I like my airplanes, yes (hats off to the de Havilland Mosquito, that twin engine plywood wonder) but I’m also a big fan of tanks. Last week I officially added to my bucket list a visit to the Tank Museum in Bovington. Camp Bovington in Dorset is the birthplace of the tank, and Camp Bovington’s Tank Museum has on display the largest collection of tanks in the world. One day I will make that pilgrimage…

I’ve been thinking about armoured vehicles a little more than usual recently. Perhaps this has been because some large construction sites that I’ve worked on lately have felt a bit like urban battlegrounds, bustling with big machines, and complete with all the smoke, dust, noise, and chaos of an urban war zone set against a ruinous backdrop of a half demolished/half rebuilt city. Reminiscent of that time in 1942 when I stood with my comrades in defence of the Stalingrad Tractor Factory? Hmm, maybe only just a little.

After an epic binge on David Fletcher’s Tank Chats last week, I decided that a blogpost about my two favourite Christchurch tanks was long overdue. First though, a few fast facts about tanks. The tank as we know it was developed in 1915 as an experimental weapon to break the stalemate of the trenches on the Western Front (Lest we forget). The Brits were the first to put the tank into battle, at the Somme in September 1916, where it had some success. The first British tank was called ‘Little Willy’. Little Willy was soon replaced by ‘Big Willy’ (the rhomboid shaped Mark 1) because Little Willy wasn’t long enough to cross trenches (sometimes it seems, size IS everything). Tanks were not actually developed by the Army, as one would naturally assume, but by the Navy, and they called them ‘Landships’. To throw the Boche off the scent, a less descriptive name was adopted as a security measure – tanks. The name stuck. Water tanks as a war winning wonder weapon? Yeah right! Codewords always work in wartime.

Of course, not all tanks are weapons of war, and the tanks that have popped up in Christchurch’s archaeological record in recent times were not designed and built to serve as offensive weapons, though they certainly did play a part in fighting different sorts of battles. So, let me tell you about two of my favourite Christchurch tanks.

The Fire Tank

I had my first run in with one of the city’s fire tanks in a trench on Manchester Street in July 2015, when SCIRT were digging up the road to lay a new water mains pipe. It was well concealed at shallow depth below the road surface, and at first glance I was a little intimidated by its immense size – it was nearly 40 metres long!

The Manchester Street tank, as first exposed. Image: Hamish Williams.

The fire tank on Manchester Street was one of six built by the City Council in 1885 for the fire brigade so they could better wage war against fire. Fire was a serious and recurrent threat to Christchurch in the early years, because so many buildings were of timber construction and they often stood so close to each other. A small fire in one building could very quickly turn into an inferno capable of destroying a whole city block. Because the council did not begin works on developing a high pressure piped water supply system until 1909, at first the fire brigade had to make do fighting the flames with water they got from local wells, or with what could be pumped directly from the Avon River. This was a less than satisfactory arrangement, especially when wells were dry, artesians yielded only a trickle, or worse still, if fires broke out at some distance from the river, and the fire brigade’s hoses weren’t long enough.

Each of the six tanks built in 1885 had a capacity of 25,000 gallons (approximately 114,000 litres) and were capable of supplying water over a radius of 1000 feet (305 metres). Each tank cost £300 to build, and each were served by their own artesian wells (Press 31/12/1884:2). Just completed, in September 1885 the Manchester Street tank was the lucky tank selected for official testing.  It was calculated that the steam powered pumps of the brigade’s two fire engines ‘Deluge’ and ‘Extinguisher’ would be able to drain the entire tank in just over 33 minutes, however they managed to empty it in 31 minutes – quite an impressive achievement (Star 23/9/1885:2, Star 29/9/1885:3). In the following years the underground tanks proved to be an efficient weapon that saved people and property, however they sometimes had a tendency to overflow through their manhole access covers, of which there was one at each end (Press 12/1/1886:2). Even after the fire tanks were to some extent made obsolete – when the high pressure water reticulation network was finally laid on – these underground fire tanks were not forgotten or destroyed, but were retained, held back in ‘strategic reserve’, just in case.

Well built, the fire tank had an arched roof and brick walls three layers thick, with an internal width of 2.2 metres and a height of 1.8 metres. Despite the efforts of two pumps, it was not possible to remove all of the water from the tank, which had its crown arch broken out so the new water mains pipe could be laid right through its entire length. It was difficult to investigate this feature because of all the water, and because this tank was technically a confined space, our access was restricted on safety grounds. Tanks sure can be dangerous for archaeologists!

The fire tank stands out as a favourite tank of mine not just because of its impressive size, but also because, like many of the 19th century structural features about the city that we have been lucky enough to investigate, it had been built entirely by hand, brick by brick. Furthermore, these bricks had been laid in a bloody great big deep trench that had been dug by hand, in a part of the city where there are elevated groundwater levels. Build a massive underground water tank in a swamp? Best of British to you mate!

Ship Tank

Much smaller than the fire tank, the ship tank was uncovered earlier this year at shallow depth in what was originally the backyard of the Occidental Hotel. This 4 ft cubic tank of mild steel had been buried in the ground for use, we strongly suspect, as a cesspit. When the hotel was connected to the city’s newly completed sewer system in 1882, the tank was filled in, mostly with bricks and other building debris that we reckon came from the demolition of the back part of the hotel.

Brick rubble in the tank. The foundations of the hotel’s fireplace was built from the same kind of bricks that were dumped in the tank – so there’s a connection there. Image: Hamish Williams.

In amongst the fill of the tank, we found a large cast-iron lid of 480 mm diameter that provided confirmation for us that this old steel tank was in fact a repurposed ship tank, made by John Bellamy’s tank works in Millwall, London. From the 1850s these riveted steel boxes with tight fitting circular lids began, in increasing numbers, to replace wooden barrels for the transport of drinking water and other perishable items in the holds of ships. Ship tanks have been found in numerous 19th century archaeological contexts across the world. In Australia, ship tanks were cleverly adapted for other uses, including rainwater tanks, sheep dips, eucalyptus oil stills and water troughs (Pearson 1992). A John Bellamy tank of identical form has also been found at Lusitania Bay on sub-Antarctic Macquarie Island, where it is suspected to have been used for the storage of penguin oil, of all things.

The cast-iron ship tank lid, marked JOHN BELLAMY  BYNG STREET/ MILLWALL  LONDON. In the middle of the lid is a central bung, which could be removed to allow access to the tank without having to remove the whole lid. Image: Hamish Williams.

It’s hard to say which Christchurch tank is actually my favourite of the two, both have their charms. I think that if I had to choose just one though, I would have to choose the ship tank. Why? Because the ship tank that we found behind the hotel demonstrates adaptive reuse – something that archaeologists always have to consider when making interpretations about things from the past. Over their lifetime, artefacts both big and small can be modified to serve different functions, and these modifications can reflect different owners, ideas, and changing circumstances (among an infinite number of other possible things). An impervious steel tank built for the storage of water was later modified for the purpose of storing poo, well before the completion of Christchurch’s sewerage system meant that on site poo storage was no longer necessary. On top of this, the tank ended its use-life as a convenient place for dumping rubbish. In a similar vein I suppose, the modified ship tank reminds me of different kind of Christchurch tank –the Bob Semple Tank. If the perceived threat of Japanese invasion at the outbreak of World War 2 makes you think about how you can defend New Zealand’s shores when your Home Defence force has no tanks, all you need to do is modify, arm, and armour up a bunch of old Public Works Department D8 caterpillar tractors in a most Monty Python-esque fashion in the local railway workshop. It doesn’t even matter if you don’t have any standardised design blueprints, or if you don’t even know whether it will work. If the enemy don’t arrive, and your underpowered, under-armoured, silly looking impractical tractor tanks end up being the target of public ridicule, hey, you can always find another use for them, you can always change them back.

Under the rocks and stones there is water underground

Living in Christchurch, I am grateful for many things, especially the quality of the tap water.  In Christchurch we are very lucky because our tap water is of such purity that it doesn’t need to be treated with chlorine like many cities have to, which means it tastes so good [never fear – the Council closely monitors quality]. Christchurch’s water is so pure because it comes not from river, stream, or desalination plant, but is sourced from natural underground reservoirs called aquifers – water saturated geological substrata that lie at great depth beneath the city. The story of Christchurch water is an interesting one and lately in the office we’ve been talking a lot about the subject, especially after the recent discoveries of some fascinating old wells in the central city. So, grab a glass of two parts hydrogen and one part oxygen and stick around for a taste of what we have learnt about water supply in 19th century Christchurch from archaeology.

The first brick well of 2017. Well, can you feel the excitement? Image: Angel Trendafilov.

Christchurch was quite unusual compared to most other cities as the local council built a sewerage system (this was completed in late 1882) long before it laid on a high pressure piped water supply (works began on this in 1909). Historically it’s usually the other way round – first comes water then comes the sewers, if both of these weren’t constructed at the same time. Part of the reason for this was the fact that Christchurch was built on a swamp next to a river, so finding water was not a particularly difficult task for early settlers.

As things typically are on a swamp, you don’t have to dig very deep to hit the water table, so shallow wells were reasonably commonplace in the first few decades of the settlement. We have found a good number of these shallow wells – mostly of a circular shape, with an average diameter of 900 mm and lined with bricks. The depth of those has varied somewhat. The shallowest we have found was only 1.6 m deep, and the deepest went down more than 3 m. Often however we don’t get to excavate them in their entirety, either because of safety considerations, or because the depth of the excavation means that the bottoms of these features can stay in situ.

This brick lined well took the top prize for best well of 2016, SCIRT found it when they were laying a new sewer mains in Richmond. The bricks that lined the upper part of the well were missing – salvaged for reuse we reckon. Image: Hamish Williams.

On a Lichfield Street site we found a well that was lined not with bricks but with two wooden barrels stacked atop each other. At the bottom of this barrel well was a large block of porous limestone – we reckon this functioned as a water filter. We can only guess how effective this was.

The barrel lined well – the timber staves were very well preserved. At left is the outside of both barrels, and at right after we sectioned it, showing the fill inside. Unlike a lot of infilled wells, this one didn’t contain very many artefacts. Both image: Hamish Williams.

The bottom of the barrel well was filled with fine grey silt not dissimilar to liquefaction silt- was this well abandoned because it silted up as a result of a 19th century earthquake event? Hamish still ponders this – but he will probably never ever know for certain because Underground Overground Archaeology’s flux capacitor is broken. Image: Hamish Williams.

The problem with shallow wells was that they got easily contaminated – many people got crook and some even died from drinking sewage contaminated water. To some extent this problem was overcome by the council banning long drops/privys and their subsurface cesspits, and later with the construction of a proper sewer system, but mostly it was the geological discovery of the artesian aquifer system below the city. Because these artesian aquifers were located super deep, there was a much lesser risk of their becoming contaminated.

When the groundwater in an aquifer is under pressure greater than the pressure that exists at ground level, these waters are called artesians. If the geology is just right, these waters rise up naturally through cracks in the ground to surface as springs. In fact, the source of the Ōtākaro/Avon River and its tributary streams are artesian springs. In addition to fracturing many underground water pipes, the earthquakes also fractured the ground in many places, which allowed new artesian springs to rise to the surface. A well drilling frenzy to tap these artesian aquifers struck the city in the 1860s. By January 1872 a total of 654 artesian wells in the city had been sunk – both on private property and in the street by the council for public use (Weeber 2000: 11). By the late 1870s the water level in the uppermost aquifer, into which most of these earlier wells were sunk, was starting to decline (Lyttelton Times 17/10/1879:6). Once gushers, many of these artesian wells (often also called  ‘tube wells’) were fast becoming tricklers, necessitating the increased adoption of pumps, or the drilling of new wells to tap deeper and more reliable aquifers.

Old artesian wells are reasonably common finds on archaeological sites about the city and typically take the form of small diameter iron pipes sticking out the ground. The tops of these are often surrounded by larger diameter glazed earthenware pipes, which served as well casings or reservoir chambers to which hand pumps or taps would have sometimes been fitted. Often it’s hard to tell conclusively whether artesian wells of this form are 19th century or not. There is often very little difference in form between 19th and 20th century artesians, and, because water mains were only laid on incrementally throughout the city in the early 20th century, the sinking of artesian wells in people’s backyards continued in some places well into the 1950s. I will always remember the first artesian I found on a site. Disturbance from the digger brought forth a small trickle of tepid water (I remember it was a bloody freezing winters day and the artesian waters that came up out the ground were steaming). Left unchecked over the weekend, this artesian trickle transformed the excavation into a small lake, much to the delight of the local ducks.

An old ‘live’ artesian well – left unchecked and unattended, this one flooded the excavation over the weekend. By the time this photo was taken, half the water has been pumped out. Can you spot the high tide mark? Image: Hamish Williams.

Not long ago we found a brick well on a site that had an artesian pipe sticking out the middle of it, and close by, another artesian pipe sticking out of an adjacent rubbish pit. We interpreted these two artesian pipes as possible evidence of the 19th century decline of the uppermost aquifer that most of the early artesians tapped. The brick well was early – maybe 1860s (we could tell this from the bricks) so we are pretty confident that the brick well came first. Whether because the water in this well dried up or the water got fouled, it at some stage thereafter was filled in, before an artesian well was sunk down through the middle of it. Later on we suspect that the water from the artesian started to decline, so a second artesian was sunk next to it, probably to a deeper level in order to tap a more reliable aquifer. What do you think about our interpretation?

At left, rubbish pit, and at right, brick lined well. Image: Hamish Williams.

I suppose that the story of how the people of early Christchurch got their water, and how this changed over time is a bit like life. In the beginning things are often easy, you don’t have to work too hard to get what you are looking for – you can find what sustains you just by scratching away at the surface a little. Sometimes however things inevitably change, (often as a result of external factors) so you have to adapt, give up on the old way of doing things and adopt new methods. Start afresh by digging a bit deeper – it can be hard going at first, but the rewards are worth it. When things change again, you just got to dig a little deeper once more, but second time around its always a little easier. Because, like a Zen master, we have learnt from previous experience that by going deeper within, while at the same time being grateful for what nature provides, you can always find a way.

An archaeological treasure trove!

As explained at length in the past, archaeologists don’t much like the use of the word ‘treasure‘. But this really is an archaeological treasure trove – lots and lots of artefacts, from which we shall learn lots and lots of fantastic information. Angel is responsible for this beautifully excavated feature, which we think was probably associated with the London and Paris House, a fancy goods store on Colombo Street in the 1860s and early 1870s. Enjoy!

2016: It’s the end of the year as we know it

The end of year is upon us again, and Underground Overground Archaeology is closing the boxes on our finds for the year.

The year we finished up our Christmas party with a scavenger hunt around the central city using cryptic clues to revisit spots important to the city and to Underground Overground. It seems archaeologists can’t help but constantly revisit the past, be it their own or others, and with that in mind it’s time to look back on the year that’s been.

2016 has been another busy one, and it feels like we’ve done even more archaeology than normal, thanks to that bloody leap day in February. Here’s a few highlights from the year that’s been.

2015. Another year down!

It’s that time of year again. Behold! Some of our favourite discoveries and images from 2015. It’s been an eventful twelve months.

Archaeology happened. Sites were surveyed, excavated, photographed, investigated, disseminated and ruminated upon. Clues were followed and mysteries unravelled. Adventures were had. Memories were made.

We really brought the glamour back to archaeology this year. This site yielded our largest assemblage for the year and ended up being one of the most interesting sites we’ve investigated in Christchurch, encompassing entrepreneurship, early artefacts, political machinations and many other aspects of the city’s history. Image: K.

Eventually, in 1893 the whole house was dismantled and rebuilt on 1890s foundations using some of the original 1871 material, leaving a mixture of 1871 and 1893 materials and styles in the house to baffle future archaeologists.
