Malayan Tin - Gravel pump and Hydraulicing: The group of employees have their midday meal in the Kongsi of the Wan Yuen Tin Mines. They get a basic wage for an eight hour day of $1.20 for skilled workers, and $1 a day for unskilled labor. This includes board and lodgings. The majority of the workers live in the Kongsi, the Chinese equivalent of the traditional Indian 'coolie lines'. Workers who live out get an extra 80 cents food allowance per shift. They get three meals a day, five feast days per year, free tea and medical treatment, and come under a compulsory workmen's compensation scheme. July 01, 1951. (Photo by British Official Photograph).
