Unconquerable Spirit: George Stow and the landscapes of the San

In 2008, the exhibition 'Unconquerable Spirit: George Stow and the landscapes of the San' opened at the Iziko Museum of South Africa. Curated by Pippa Skotnes, the exhibition featured the work of a relatively unknown figure in 19th century South African history. George William Stow was a British born, South African geologist, ethnologist, poet, historian, artist, cartographer, and writer who was responsible for a creating large collection of watercolours and drawings that documented the rock art he found in the caves and shelters of South Africa. The exhibition brought together a vast range of materials representing Stow’s life and the period in which it was produced – from his drawings and paintings; his letters, documents, and poems; to his maps, and field diaries. The display shows one map in particular which is kept as part of the National Library of South Africa collections, and was drawn by Stow during the period he was conducting geological surveys of the country surrounding the diamond fields of Kimberley, down to the junction of the Orange and Vaal rivers and beyond. It shows amongst other things, the diamondiferous deposits of the Vaal river during the late 19th century and, as part of this section of the exhibition which focused on Stow the geologist, Skotnes displayed it alongside relevant disciplinary materials she sourced from the Department of Geological Sciences, University of Cape Town.

"Stow’s discovery of coal deposits in 1878, found in the beds of the Vaal River, was of interest to the diamond magnate, Sammy Marks. Marks realised the importance of Stow’s discovery and the opportunity for using coal at the Kimberley diamond fields for energy generation (Leigh, 1968:112). He believed he could transport the coal from Vereeniging to Kimberley by floating it down-river by a series of weirs to his diamond claims. This turned out to be impractical and he had to resort to using ox-wagons as a method of transport instead (Leigh 1968:17). Marks & Lewis who at that time owned a quarter of all the Kimberley diamond claims, sold most of their Kimberley claims to concentrate on the coal finds through their newly formed mining company, the Zuid-Afrikaansche en Oranje Vrystaatsche Mineralen en Mijnbouvereeniging (later to become the Vereeniging Estates Limited). In 1892, the small village of Vereeniging was formally established" (Liebenberg 2021).

The Diamond Mines of South Africa: Some Account of their Rise and Development.

“In the mines operated by the De Beers Company alone, more than eleven thousand African natives are employed below and above ground, coming from the Transvaal, Basutoland, and Bechuanaland, from districts far north of the Limpopo and the Zambesi, and from the Cape Colony on the east and the south to meet the swarms flocking from Delagoa Bay and countries along the coast of the Indian Ocean, while a few cross the continent from Damaraland and Namaqualand, and the coast washed by the Atlantic. The larger number are roughly classed as Basutos, Shanganes, M'umbanes, and Zulus, but there are many Batlapins from Bechuanaland, Amafengu, and a sprinkling of nearly every other tribe in South Africa” (Williams 1902: 412-413).

The Diamond Mines of South Africa: Some Account of their Rise and Development.

“The initial impetus for establishing a collection of mantle materials for research purposes in South Africa was provided by Gardner Williams and his son Alpheus Williams in the late 19th and early 20th century. These two American mining engineers shared a great interest in the mining methods and geology of the South African kimberlite-hosted diamond mines they were supervising. Each wrote books on the subject and the two men assembled a collection of scientifically interesting rock samples and minerals from the mines. Subsequent to the death of Alpheus Williams, the Williams family donated this collection to the Geology Department at UCT for teaching and research purposes” (Department of Geological Sciences 2021).

The South African College

“UCT was founded in 1829 as the South African College, a high school for boys. The College had a small tertiary-education facility that grew substantially after 1880, when the discovery of gold and diamonds in the north – and the resulting demand for skills in mining – gave it the financial boost it needed to grow. The College developed into a fully fledged university during the period 1880 to 1900, thanks to increased funding from private sources and the government. During these years, the College built its first dedicated science laboratories, and started the departments of mineralogy and geology to meet the need for skilled personnel in the country's emerging diamond and gold-mining industries” (University of Cape Town 2021).

Haematite Miner's Lung (Or Sidero-silicosis)

Catalogue No: R3-d55-0331. Origin: UCT Anat Path museum. Old Museum No: V:x:6. Year: not recorded. Clinical data: No further clinical or laboratory details are available other than that the patient was an emaciated 50 year old man. Macroscopy: The specimens preserved are both lungs, the heart, kidneys, spleen and and portions of liver. In the thorax, both pleural cavities were completely obliterated by a fibrous pleurisy of long-standing and both lungs were universally adherent throughout. They were stripped off with difficulty and were found to have thickening of the pleura over the upper lobe on the left side and the upper and middle lobes on the right. The lower lobes on both sides were soft and spongy while the upper lobes were dense and firm on palpation but on section there was no cavitation and no evidence of tuberculosis. The left lung showed a dense fibrosis of the whole of the upper lobe and the upper third of the lower lobe; no crepitant lung tissue could be found in the upper lobe while the lower two-thirds of the lower was crepitant and showed emphysema of a hypertrophic nature. The lung was a dull brick colour and haematite dust flowed out with the fluid when the lung was sectioned. The right lung presented a similar appearance to the left. There was a solid dense fibrosis of the upper and middle lobes and the lower lobe showed fibrosis with hypertrophic emphysema. There was no evidence of tuberculosis and on palpation, a dense fibrosis was found with no nodular formation whatever. On section, it showed a similar appearance of a brick-dust colour, dilated bronchi and uniform fibrosis of the upper and middle lobes with no crepitant lung tissue. The pericardial sac was slightly increased in size due to a hypertrophied and dilated heart. The hypertrophy was mostly on the right side and there was a terminal dilatation of the right atrium; the valves and coronary vessels unremarkable.The liver was small and on section showed venous congestion and cloudy swelling. Microscopy: On microscopy, sections of lung show a diffuse fibrosis of both upper lobes with no recognizable lung tissue. The fibrosis in areas has a slightly whorled arrangement, the centre of which is hyaline and contains no iron pigment and surrounding it is a zone of cellular tissue containing masses of iron. In the upper part of the lower lobe where the lung tissue is recognizable as such, a few nodules definitely resembling silica nodules are to be seen. In the both lower lobes a solid oedema was noted and emphysema marked. The fibrosis was not present to anything like the same extent in the lower lobes, the emphysema being the most marked feature. No evidence of tuberculosis was found in either lung, though a calcareous gland was found in the hilum. Under polarised light, the iron showed up as a golden brown with a few points of light, clear, needle-like in contra-distinction to the iron lying free in the fibrous tissue. The macrophages are beautifully shown lying inside the alveoli filled with iron dust. Percentage of Ash 16.6 Percentage of silica to ash 6.6 Percentage of silica to dry lung 1.1 Percentage of iron to ash 10.3 Percentage of iron to dry lung 6.7 Comments: In summary, the post mortem findings were of: Dense pulmonary fibrosis; hypertrophied and dilated right ventricle; failure of compensation. This condition is described as haematite miner's lung or sidero-silicosis, caused by the inhalation of dust containing silica and ferric oxide which is the principal component of the ore. The fibrosis is thought to be caused primarily by the silica and the exact role of the iron pigment in the pathogenesis of the lesion is not clear. The earliest lesions occur as small densely fibrous, sub-pleural foci usually in the upper lobes; these grow by coalescence of adjacent foci until a diffuse fibrosis of the whole lobe is produced. Haematite miner's fibrosis is commonly associated with tuberculosis and other chronic lung infections; in addition there is quite a high incidence of carcinoma of the lung reported in these cases.

Smallpox

"In Kimberley in 1883-4, several leading doctors with links to the diamond-mining industry publicly denied the presence of smallpox among migrant workers, instead diagnosing them as suffering from a rare skin disease. They appear to have done so lest admitting that the dreaded smallpox was raging, which would have affected the supply of labour and materiel and thereby interrupting mining operations. Led by Cecil Rhodes’s friend, Dr Leander Starr Jameson, measures to curb the epidemic were sporadic or, in the mining compounds, non-existent, and cases topped 2000, with mortality at 3.5 per cent of the population. Only when the colonial government eventually called in external doctors to diagnose the disease, was the cover-up terminated and vaccination, fumigation and isolation vigorously pursued. The conspiracy of denial, by retarding action and sowing doubt about the need to be vaccinated, had been responsible for no small percentage of the 700 deaths in the town" (Phillips 2012: 32-33).

What UCT is not telling its first years

On the 19th of January 2015, an article appeared in the Cape Argus titled 'What UCT is not telling its first years' written by Dr Siona O’Connell, a staff member of the Centre for Curating the Archive, and lecturer at the university. In it she wrote about the absence of transformation in the university, evident in its lack of black academic staff, describing the campus as "mired in unarticulated tensions and divisions, many of them pivoting on race” and “guarded by the Rhodes Memorial – a significant imperialist edifice” that continues to shadow it “in many overt and covert ways” "(O’Connell 2015). In the article she pinpoints that even though, as first years, they will most certainly be greeted by the statue of Cecil John Rhodes overlooking the rugby field during their tour of the campus, their chances of being taught by a black professor during the full span of their degree, will be incredibly slim…

Canary

Sentinel species are used to detect risks to humans by providing advance warning of a danger. The idea of placing warm-blooded animals in a mine to detect carbon monoxide was first proposed by the Scottish physiologist John Scott Haldane in 1913. Canaries (Serinus canaria ) were considered the best sentinel animals for detection of dangerous gases because they were found to be more sensitive than other species evaluated (Pollock 2016:386-387).

An Experiment on a Bird in the Air Pump

In Joseph Wright’s 'An Experiment on a Bird in the Air Pump' (1768), he depicts the re-enactment of Boyle’s famous experiment. Contrary to the restricted viewing of this experiment in the confines of Gresham College by the gentleman of the Royal Society, this audience includes a variety of individuals of different ages and gender, exhibiting a mixture of emotions: a young girl worriedly watches the fate of the bird, while another is comforted by her father, seemingly too upset to view the rest of the experiment; a young boy and middle-aged man look on with absorption, while two young lovers only have eyes for each other; lastly an old man meditates on a skull in a jar, and the scientist stare out at the viewer, and not at the experiment.
