When the authorities attempted to suppress the activities of the Chinese clans, labelling them secret societies, it was James Logan who helped the Chinese merchants in submitting petitions. This resulted in greater rights and recognition for their organisations and festivals.
The death of James Logan in 1869 was regarded as a huge public calamity. The public of the Straits Settlement pooled a fund to erect a memorial in his honour, the Logan Memorial. The memorial stood on the grounds of the Supreme Court, in memory of his deed for the people. It was briefly moved during World War II, but returned to its located in front of the Supreme Court building, until 2007, when it was moved to a new permanent location across the street, following the renovation and expansion of the Supreme Court building.
