Mining Lamp, E. Thomas and Williams Ltd, Welsh Mining Lamp
This lamp is typical of lamps used in Welsh Coal Mines. It was purchased from the supplier around mid 1995. The Welsh Miners’ Lamps were ingeniously designed over 180 years ago to alert coal miners to danger. It ensures the burning of a protected flame in the presence of explosive gas, by regulating the necessary supply of atmospheric air, and by allowing the products of combustion to pass through without igniting the gaseous atmosphere. If the atmosphere is so heavily charged that noxious gas enters the lamp, its presence will be indicated by a change in the length and color of the flame, and (unless there are exceptional circumstances), the miner has sufficient warning to secure his safety. (http://www.welshminerslamps.com/info_lamp_personaluse.shtml, accessed 06/05/2015) E. Thomas & Williams, Ltd. mining lamps have been in continuous production since 1860. Cambrian Lamps are approved for use in coal mines where methan gas and oxygem deficinecy are hazards.Solid Brass traditional miners Flame Safety Lamp with Copper Chimney. The base of this lamp is tooled from solid brass because brass does not spark when it hits rock and is therefore the safest metal to use underground. The lamp burns lamp oil (kerosene). R.

Plan, Sulieman Pasha Co Plan Transverse Section
The Sulieman Pasha is possibly named after the most important Sultan of the Ottoman Empire, Suleiman One, or Suleiman the Magnificent, when the Ottoman Empire was at its peak. Or potentially a number of Ottoman governors, statesmen and military commanders with the same name after, however the spelling is slightly different to the mine name. No Turkish connection was found relating to the formation of the company, and remains unconfirmed. The mine operated from two shafts; No. 1 near the corner of Humffray and Mair streets, and also near where the Welcome Nugget (2217 ounces) was found years earlier; and the controversial No. 2 shaft several blocks south bordering the northern side of the main highway through Ballarat. The company produced 62 666 ounces of gold, the twelfth highest quartz reef gold production for any mine on the Ballarat goldfield. Some crushing figure examples are January-June 1881: 3674 tonnes 1085 ounces; January-June 1885: 2949 tonnes 1281 ounces; July-December 1885: 4459 tonnes 1119 ounces; January-June 1887: 1869 tonnes 730 ounces; July-December 1892: 1450 tonnes 771 ounces; July-December 1896: 4365 tonnes 1372 ounces. Like many mines in the area, gold grades were low. John Watson was noted as mine manager in the 1880s, and John Williams 1890s. The company was re-organised twice increasing the number of shares from 4000 to 24 000, and increasing the capital available. The Sulieman Pasha Company was formed in 1878. David Fitzpatrick was given the honour of turning the first sod of both the No.1 and later No. 2 shafts. The first dividend was given to shareholders in July 1881. The company obtained a prospecting vote (government grant) to start, and was very proud to be the first Victorian gold mining company to pay the funds back to the government. The event was marked by a lavish banquet laid out for ministers and government officials by the company. Leases were purchased to the south in 1885 to the Llanberris Mine boundary, after poor results began accumulating from the small No. 1 shaft. To take advantage of this new land the company planned to sink a second shaft. Initially this was to take place on government land, but the uproar from nearby residents caused the company to purchase land along the Main Road (now Western Highway), and the old Yarrowee Hotel which had occupied the site since the alluvial digger days of the 1850's was demolished. The area had since those days become heavily occupied with a number of shops, houses, a post office, church and two schools in the immediate area. The thought of an underground mine next door drew considerable opposition. The company (before the days of public relations departments) wrote 'most people would have thought that progress as vital as mining would be supported by tradesmen whose business rely on the mining industry. It seems when it comes to mining they are bereft of their senses, and considering the low ebb of mining in Ballarat East, the action of our opponents are unaccountable. (Sarcastically) There are certain engineering difficulties in moving the quartz reefs to a new location, but if we could to appease our opponents we would'. The company also wanted to take over 4 acres of the St Paul's school oval for machinery, but accused the St Paul's Church of wanting extortionate amounts of money upfront, and on a yearly basis for the privilege. It stated the church could not be opposed to mining when several years earlier it had formed its own company to mine the land, only for shareholders to lose their money. In 1886, the company approached the Minister for Mines, and attended heated public meetings on the matter. The local residents, shop owners, and church submitted a 60 person petition to the local council and government authorities. They stated the shaft contravened the mining statutes, which stating no mining could take place within 150 yards of a public building or church. A speech by a resident stated 'mining always comes with glorious pictures of the great benefits which would accrue all parties concerned if their request is granted, but if property is destroyed or depreciated in value, no-one then comes forward and compensates them'. The No. 2 shaft was approved including taking over part of the school oval. In 1888, workers at the company's No. 2 shaft went on strike to try and bring their wages in line with other mines in the district (the No. 1 shaft was operated by tributers). William Madden (26) was killed from a fall of earth underground the same year, while a year later his father John Madden (70) was similarly killed in the Madame Berry Mine elsewhere in the district. In 1897 as the amount of gold being found fell away, it came to light part of the deal to purchase the Yarrowee Hotel site was a 5% royalty on gold found. Shareholders could not understand why they were paying a royalty to the former owners of the property. The mine closed in 1898 due to a lack of gold. In 1902 a boy (age unknown) called Charles Lee was killed from a fractured skull while working to dismantle the Sulieman Pasha plant. The fuss over the No. 2 shaft had a sequel. On the company winding up, the land was purchased by J.S. Trethowan who built a house next to the shaft. In 1907, the shaft caved-in creating a sinkhole immediately at the back of the house. A Mr Chamberlain heard a deep rumbling sound at 5am, and looked out the window to see his fowl house and thirteen chickens disappear down an expanding hole. He then went back to bed, and called the police later in the day. The shaft was 1050 feet deep, and the hole at the surface that developed was 20 feet by 17 feet across, and 20 feet depth. In 1930 it is reported a syndicate had been formed to clean out the old shaft, and re-open the mine. It is assumed this was the No. 1 shaft but no more was found.

Financial record - Receipt Book, Department of Works and Mines Victoria, July 1936 (first record)
Establishment and Functions Prior to 1860, the Chief Secretary's Department had been responsible for the administration of the gold fields and associated mining activities. In November 1860 a Commissioner of Mines was appointed and a Department was established under his administration. For the period November 1861 to June 1863, the Postmaster General was responsible for the Mining Department. A Minister of Mines was again appointed in 1863. Responsibilities of the Department of Mines were: 1. Regulation of mining and related public works activities through the issue of miners rights, business and residence licences, mining leases, mineral and other prospecting licences 2. Superintendence of the activities of mining surveyors, registrars, wardens and Mining Boards. 3. Investigation of the state's geological structure, mineral wealth and underground water resources 4. Development of the mining industry 5. Supervision of the safe working of mines, machinery and quarries including checking the credential of mine managers, inspectors and operators 6. Regulation of the disposal of sludge and other waste products 7. Administration of the Victorian Mining Accident Relief Fund. Arising from its initial responsibility for the supply of water on the gold fields, the Department became responsible for rural water supply from the mid 1860s. Statutory responsibility for rural water works during this period rested with the Board of Land and Works. In 1865 the Waterworks Act gave the Board power to construct waterworks, purchase land, levy charges and lease or sell works, while the Public Loans Act 1865 empowered it to provide loans to local water trusts for waterworks. The actual administration of these statutory provisions was undertaken by the Victorian Water Supply Department which operated from 1865 to 1889 as a sub-department of the Department of Mines, from 1889 as a department in its own right, and from 1895 to 1909 as a sub-department of the Department of Mines and Water Supply. For a brief period from 1891 to 1893 the Department of Mines was also responsible for forests and, until 1880, for the Schools of Mines subsequently transferred to the Education Department. In 1895 the Department of Mines and the Victorian Water Supply Department were amalgamated to form the Department of Mines and Water Supply.
