The old Kedah-Patani trade-route
A descriptive account by A. W. Hamilton tracing the old overland trade route from Kuala Nerang in Kedah to Patani in Siam, published in the Journal of the Straits Branch of the Royal Asiatic Society in 1922.
Summary
Hamilton provides a detailed walking description of the route from Kuala Nerang through Padang Sanai, Kuala Seraya, and Durian Burong, following the course of the Padang Terap stream and its tributaries (p. 389–390). He notes the sparse Malay settlements, the abandoned Quarantine Station at Kuala Seraya, and the deserted village of Kampong To Naidam Mok, named after a former Siamese official in charge of cattle quarantine and dues (p. 391).
The route then enters the forested hills, following the Sungai Genting Pahat to the actual Genting Pahat cutting — a narrow defile approximately fifty yards long and ten feet deep, likely formed by the coalescence of two small stream valleys (p. 392). The boundary stone (No. 34) marking the Kedah–Siam frontier stands in the centre of the cutting, beyond which lies the Siamese village of Senaok and the open road to Patani (p. 392).
