The document discusses the history of coal, rubber, and oil industries in Brunei between 1883-1924. It notes that coal mining concessions were granted in 1883 and produced over 652,000 tonnes of coal by 1888-1924. The discovery of oil in 1899 near Kg. Ayer Berkunchi led to the oil industry, which became more profitable than coal. The boom in these extractive industries increased jobs and population in Muara, leading to more infrastructure like shops, roads, and postal services to support the growing town. However, the coal industry declined after World War I as prices became unstable and oil from Pulau Berambang was discovered to be more profitable.
