Rubber was also a popular agricultural industry in Jurong at that time and was regarded as a strong competitor to the gambier plantation businesses and firms that were flourishing and expanding in the district. By the first half of the 20th century, the practices of rubber-tapping and the setting up of rubber plantations overtook the role of planting and harvesting gambier, an agricultural activity that once thrived in Jurong. A notable example of a business dealing in gambier that shifted to the rubber-plantation sector was the plantation firm that belonged to Chinese business-magnate Chew Boon Lay. The large amount of land that his plantation stood on was often well-associated with his name. Today, this area is known as Boon Lay Place and is a small subzone that is enclaved within the new town of Jurong West.
