No records of the shaft being used as a convict lockup or for storage of supplies or of it even existing have been located in the official reports of the colonial surveyors, police, superintendents of the iron-gangs, the journals of William Cox the road builder, Sir Thomas Mitchell the Surveyor General and supervising engineer on the Western Road, the account of Governor Macquarie’s journey over the new road in 1815 or any of the accounts of early 19th Century travellers over the Blue Mountains to Bathurst (Mackaness 1965), not does it appear on the 1878 Parish of Linden survey (Dept. of Lands 1878).

Historical records show the convicts who laboured on building William Cox’s 1815 road across the Blue Mountains were skilled workers and tradesman – masons, cobblers, smiths and carpenters, they welcomed the chance to earn a pardon, their ticket of leave or emancipation (Yeaman 1983). By the 1830s there were well established convict stockades at Springwood, Mt Victoria and Cox’s river. At Mt Victoria in addition to a tall stockade fence built from upright stakes to enclose the convicts, there were barracks for the soldiers, constables' huts, a cottage for the officers, a Commandant's house and a store house on this major site. So there was already an efficient stockade system in operation and troublesome men were punished by being put in leg irons and chains. The surviving contemporary accounts of life in these stockades emphasise the fact that the convict road gangs moved on as the road building progressed, and all wore distinctively marked convict clothing to discourage escaping (Karskens 1984).
Would the shaft have been an efficient way of holding convicts? The mean height of male convicts around 1820 was 168 cm - about 5 foot 5 inches (Nicholas 1988 p. 81). Even allowing for their smaller size, three or four men lying down would be a cosy fit and five or six standing in the narrow space would be pretty squishy but with more than five metres of waste space above them. The ‘convict hole’ is a myth, a piece of local folklore and the idea is untenable.
The shaft would also be impractical for the storage of supplies because of its narrow vertical nature; it is simply the wrong shape. There is a small, partially excavated earth and rock chamber at Bull’s Camp, also known popularly as the ‘convict hole’ which in fact was used by the road builders for storage of tools, equipment and explosives (Merriman 2014).
Another suggestion has been that it was a kiln for producing lime for building or tanning and that the tunnel at the base was for air draft (Fox 2009). However there are no commercial deposits of limestone in the area, the nearest being at Wallerawang or Portland. The common feature of early calcining kilns was a wide, shallow egg-cup shaped burning chamber, with an air inlet at the base known as the "eye", all constructed of brick. This type of brick kiln occurs at Hill End and there is even a brick, shale processing kiln at Mt Victoria at the Asgard Swamp Mine (Higginbotham and Jack 1982). Heap and pit burning were used from the early days of settlement to produce lime from shell, and where simple shaft kilns were used they incorporated a separate brick firing chamber and ash boxes with brick or iron fire bars (Pearson 1990). None of this is in evidence at the Somers Street shaft and close inspection of the interior shows no evidence of intense heat such as soot accumulation, and spalling of the rock face. In fact, allowing for normal weathering, the internal pick marks are still fairly sharp and display the natural sandstone colouring. Nor is there any evidence of charcoal, ash, lime waste or limestone rubble in the vicinity, something to be expected if it had been a calcining kiln.

This area at the end of Somers Street below the cliff line has some of the best grazing land in Lawson and from the 1840s when the first settlers arrived in the area, was known as the Cow Pasture (Bratby and Stockton 1986). It was probably the site of a dairy from the 1880s when the local population began to increase following the arrival of the railway in 1867. The Mechanic’s Institute opened in 1896, and the town soon became a significant population centre in the Mid-Mountains between Springwood and Katoomba. Lawson was also the seat of local government for all of the Blue Mountains, apart from the Katoomba and Blackheath urban areas, from 1907 to 1947 (Bentley, 1986).

The link between the shaft and dairy farming is confirmed by the minutes of Blue Mountains City Council’s Town Planning committee for 18 February 1970, which contains the following report from The Town Planner:
Proposed Historical Site, Lawson
Mr W Deverall of 70 Military Road, Dover Heights, has written to Council offering part of his land in Somers Street providing it is retained permanently as a historical site. His letter reads as follows:
“On portion of my property at Lawson there is, I think, one of the most historic mountain emblems. It is not mythic but definitely this deep stone well has been hand-chiseled out by convicts. I have studied this matter hard and after a good deal of research, I feel convinced this well has been used as an ensilage pit. At the bottom it has an opening enabling the contents to be drawn therefrom during the crossing of the Mountains or the making of the road.
This has become somewhat sacred to me and I would not like, at some future date for this historic emblem to be lost. If the Council should think the same as me about this matter, I would be pleased to dedicate this portion of my land to the Council to be kept in perpetuity.”
The ensilage pit was inspected by the Town Planning Committee in May, 1968, when the Lawson/Bullaburra Town Planning proposals were under consideration. It has not been possible to verify Mr Deverall’s statement that this is an ensilage pit but the Historical Society will be contacted before the Meeting to this end. It is considered that Council should accept Mr Deverall’s offer with a surround of approximately one acre as illustrated in the accompanying sketch No.D2357.

Before we turn to a further source of evidence for dairying on the site, let us look at milk quality and how it was determined. In the early 20th century there were two relatively simple tests for quality available in small dairies. One was a basic test of specific gravity using a lactometer to determine adulteration; this would reveal watering down of milk. The second was the Babcock test, invented in the 1890s, which was the first inexpensive and practical test that could measure the actual fat content of milk. A manual cream separator would be used to extract the cream that was either churned into butter or when combined with milk protein produces cheese, both were value added products for the dairy farmer or milk processor. The Babcock test was also utilized by farmers to selectively breed for cows producing milk of higher butter fat content.

The economics of dairy farming easily demonstrate that supplementary feeding was a worthwhile investment to maintain production. A small dairy of 15-20 milking cows producing an average of two gallons (9 litres) each per day over two milkings, much less than today’s breeds, could return around £40.0.0 per week, before costs, based on milk prices of around 4 pence per pint. The weekly basic wage in the 1920s was around £4.5.0. In today’s values £40.0.0 is equivalent to over $2,500 based on the CPI from 1920 to 2015, not a bad living, but a hard one, (see note for calculations below). Ken Porter whose family operated a dairy in north Leura in the 1930s with a milking herd of 80 cows, recalled in an oral history interview for Blue Mountains Library in 2010, that his father would get up at 2.30 am to begin milking at 4.00 am, seven days a week and his grandfather would still be making deliveries at 9.00 pm, no wonder he would often fall asleep at the dinner table; Ken began helping with the milking at age six, with his two brothers, and would often not arrive at school until 11o’clock in the morning (Levido 2010).

There are other early examples of pit silos, including the seventeen grain storage silos located in the sandstone bedrock on Cockatoo Island, these date from the 1840s, and have a small top entrance opening up to a cavity six metres deep and seven metres wide. Earth silage pits are found on dairy farms along the Nepean River at Castlereagh and may also date from as early as the 1840s (Godden et. al. 2008). The Somers Street shaft may be seen as part of an established tradition of on-farm fodder conservation and storage. Ensilage and chaff were also widely available from commercial suppliers (Maitland daily Mercury 1910) and may have been stored in the silo for protection from weather and vermin. Oats and barley were also grown locally for stock feed (Freemans’ Journal 1903).

Beginning in the late 1860s there were camps of fettlers and navvies throughout the Blue Mountains as the railway line was pushed westwards from Penrith to Wentworth Falls by 1867 and over the Great Zigzag to Bowenfels by October 1869 – here were men used to cutting through rock and they were not in short supply. In fact the labourers who worked on the Mountains line, with their families, contributed significantly to the growth and development of the towns along its route (Croft 1982).

The rock face was then cleaned up with a pick axe swung alternately from right and left, this produces the familiar angled cuts seen on many of the local railway cuttings and in our shaft. The space needed to swing the pick also determined the minimum diameter of the shaft. Although black powder and dynamite were available and used in the bigger road and rail cuttings, (Convict Trail 2017), it is unlikely they were used in our shaft for fear of shattering the cliff face. There is some evidence of coarse sandy, rock spoil in crevices on the cliff top, but most is visible as a mound at the base of the cliff outside the lower entrance tunnel, see photo.

So to summarise, the shaft post-dates the convict period and was probably excavated by skilled rock cutters employed on the numerous railway gangs living and working in the area, during the railway construction period of the 1880s and early 1900s. It is further proposed that it was the need to maintain milk production, perhaps prompted by the severe drought of the period 1896-1902, that prompted the significant economic investment in providing supplementary fodder storage, either grain or ensilage and perhaps both, that is the origin what can now be identified as the rock silo in Somers Street, Lawson.
|Ossie Smith's dairy Katoomba c. 1920|
The Mountains dairies continued to operate into the 1950s due to the demand for fresh milk by the local community that valued their local milk and wanted nothing to do with the so called ‘imported’ stuff. Before their eventual demise they were the last remnant, on a human scale, of a cultural adaptation that stretches back into prehistory and still survives in many rural and small scale societies in parts of Europe, Africa and Asia, where milch animals have included not only cows but sheep, goats, camels, donkeys, horses, buffalo and reindeer.
|Ossie Smith's milk cart c. 1920|
The importance of milk was apparent from the beginning of European settlement 1788. When the First Fleet arrived at Sydney cove, it brought one bull, four cows and one calf. These animals were to supply milk to the new colony and to serve as foundation stock for future herds. There were many setbacks in the first year (poor soils and pastures being a major concern) and within the first four months of settlement the original herd had wandered off in search of better food. Seven years later the herd was found near the Nepean River, numbering 40 cows and 2 bulls. During those early years, famine, drought and a lack of farming experience meant that many of the initial shipments of dairy cattle were slaughtered for meat. After these initial difficulties, the herd increased from 200 cows in 1796, to 1,044 in 1800 and rapidly to 34,500 head by 1825, and went on to form the basis of the dairy industry as we know it. (ABS, 2004).
Full fat cow’s milk is recognised as a good source of nutrition for brain development and generations of school children have been nurtured on milk with clear health benefits (Adee et. al. 2017). The difference now is that most children will never know the warm, rich smells of a milch cow chewing her cud, or experience the drama of a busy dairy at sunrise. Milk products are now consumer items that come from supermarket cabinets via a supply chain. The standard of nutrition of most Western countries is now so high that cow’s milk is probably unnecessary in our diet (ibid.) and is just as likely to be enjoyed in a latte or a yogurt smoothie, yet in the not so distant past the village dairy formed an essential part of small town life.
Stan Bentley for personal conversations during the 1985 research, Stan was a member of Springwood Historical Society and as a young man worked in various Blue Mountains dairies; he supplied many of the personal details of the Lawson dairy operators.
The pioneering Blue Mountains archaeologist, Fr. Eugene Stockton first alerted me to the shaft and reported finding oat hulls in the interior; he has resided in Somers Street for many years and first explored the silo in the 1960s.
