Mining built #NovaScotia!
The old #BankofMontreal building in Sydney was built 1900-01 of sandstone from Wallace, the area that provided stone for so many historic buildings like our legislature and parts of Ottawa's parliament buildings. #nspoli#cbpoli@HomeMattersCB@OldSydney
The bank was built because of the economic boom that occurred in #Sydney in that era. Large steel plants located in Sydney, fed by nearby #coal mines, made Sydney a hub of commercial and industrial activity. #nspoli#cbpoli@HomeMattersCB@OldSydney
The building was designed by renowned architect Sir Andrew Taylor of Taylor and Gordon. Its Palladian windows, copper dome, columns, and pediments combine to make a striking building. It’s one of the best examples of commercial Neo-classic architecture in NS. #nspoli#cbpoli
It was built on one of the few lots left in #Sydney’s bustling downtown core by Rhodes and Curry Company, the largest construction company in the Maritimes from 1880 until 1920. Rhodes and Curry was founded in 1876 by Nelson A. Rhodes and... #nspoli#cbpoli@HomeMattersCB
...Nathaniel A. Curry, brothers-in-law in #Amherst. Initially, they opened a door and sash factory, which burned down, was rebuilt and burnt again. After obtaining long-term financing they diversified into construction and building railcars with... @MLAElizabethNS#nspoli#cbpoli
...the purchase of the James Harris Car Company in Saint John. To maximize profits, the company acquired timber lands, sawmills, lime deposits and brickyards, so they could use their own materials and build everything from the foundations to roofs of buildings. #nspoli#cbpoli
Rhodes and Curry built thousands of homes and buildings in the Maritimes, including #Halifax’s city hall, #Sydney’s St. Andrew’s United Church (now the Highland Arts Theatre) and stations, offices, and roundhouses for the Intercolonial Railway including #Pugwash’s train station.
The Bank of Montreal’s construction was supervised by James Reid of North Sydney. Dan Gillis from Portage was also a foreman.
According to @OldSydney, which is based in the building today, when an extension was added in the 1970s it was built with concrete blocks. #nspoli#cbpoli
However, the blocks of sandstone from the exterior wall that was taken down for the extension were split into two or three slices and used as the facade for the addition so the building’s look would be maintained. #nspoli#cbpoli@HomeMattersCB@OldSydney

For example, an e-car has 183 pounds of copper wiring in it because copper is used in every major component from the motor to the inverter and the electrical wiring. There is about four times more copper in an e-car than in a car with an internal combustion engine.
There are about 400 electric cars on Nova Scotia roads - a total of over 73,000 pounds of copper!
An electric car uses 25-50 grams of silver, so Nova Scotia’s 400 e-cars contain about 15,000 grams of it.
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. (The terms cement and concrete are often used interchangeably, but cement is actually an ingredient of concrete... #nspoli
...Cement is the glue that holds concrete together.)
Reinforced concrete means the concrete is poured over a frame, usually steel bars, that give the structure greater strength. #nspoli
The short answer is yes, sinkholes are real but no, they are not a major risk and should not prevent you from enjoying outdoor activities.
Most natural sinkholes are caused by groundwater naturally eroding rocks like gypsum, salt and limestone which are water-soluble. #nspoli
The water erodes the rock, leaving an underground cavern. Eventually, the weight of the rock and earth above the cavern causes the sinkhole to form. Sinkholes can form either gradually (i.e. a small depression appears and perhaps grows larger over time) or by sudden collapse.
The New Campbellton coal mine was opened in 1862 by Charles J. Campbell, a former Member of Parliament, Member of the Legislative Assembly and executive council member. The community had been named Kelly’s Cove but was changed to New Campbellton in 1862 in honour of Mr. Campbell.
A sample of New Campbellton’s coal was sent to the 1865 Dublin Exhibition and “was very favorably noticed by the Judges,” according to a report. #nspoli#cbpoli#novascotia#capebreton#nshistory
Mining built #NovaScotia! #Halifax was founded in 1749 and its first court house is reported to have been built by 1754 on the northeastern corner of Buckingham + Argyle streets. After the building burned in 1789, the courts were temporarily housed in various buildings. #nspoli
In April 1851 a bill to provide Halifax with a county court house was passed. Mr. H.G. Hill, a prominent #Halifax architect, prepared a plan for a wooden building.
However, since the records of the county, wills, deeds and other papers of public office were... #nspoli#novascotia
...to be stored in the court house, it was important that the building be fire-proof. Also, a number of serious fires in #Halifax in 1857 led to the passage of a bylaw that required large buildings be made of stone or brick, so Hill's plans for a wooden building were abandoned.
The Sullivan Creek #coal mine, before and after!
It's one of several mines reclaimed around #AlderPoint#CapeBreton in the late 1900s/early 2000s - examples of how mining makes temporary use of land and then land can be used other ways. #nspoli#cbpoli#novascotia@JaimeBattiste
The first mine in the area was the Scotia Mine, or #NovaScotia Steel & Coal Company No. 4 Colliery, on Toronto Road, which operated on the Sydney Main (Harbour) Seam from 1915 to 1921. #nspoli#cbpoli#novascotia@JaimeBattiste
Coal quality and structural issues (including water inflow) plague the Harbour Seam west of Florence so upon closure of the colliery, production on the Harbour Seam was limited to the Company’s No. 3 Colliery in Florence, which had opened in 1902... #nspoli#cbpoli#novascotia
