Plants of Prince of Wales Island. {With an introduction H.N. Ridley
Sir William Hunter, Surgeon to the East India Company, composed this manuscript flora of Penang (Prince of Wales Island) during his residence on the island in the late 1790s, and it was published posthumously in 1909 with an introductory note by H. N. Ridley. The work documents the island’s vegetation at a formative moment in its colonial agricultural history, recording the establishment of the East India Company’s spice gardens and the early cultivation of pepper, nutmeg, and other commercial crops. Its primary value lies in providing the first systematic botanical account of Penang and the earliest recorded observations on the fruiting of nutmeg and mangosteen in the Straits Settlements.
Summary
Hunter’s manuscript is structured as a Linnaean flora, proceeding through the sexual system of classification from Monandria to Cryptogamia, with detailed morphological descriptions of each species encountered on the island. Beyond mere enumeration, the text is embedded in a narrative of colonial agricultural development: Hunter describes the physical geography of Penang, its climate (with a ten-month thermometer register), its population of approximately 20,000 divided among Chinese, Choolia, and European communities, and the economic logic of its plantations. The spice gardens of the Honourable East India Company at Ayer Hitam feature prominently throughout, as Hunter notes which species were introduced from the Moluccas via Christopher Smith’s 1796 expedition and which were already established in private or Company holdings.
The most substantial passage concerns pepper cultivation, where Hunter provides a detailed account of propagation methods, support trees (Morinda citrifolia and Erythrina corallodendron), the “laying down” technique for training vines, harvesting cycles, and processing. He includes a financial appendix calculating the projected returns on a 100,000-vine plantation over twelve years, and records that the island’s total pepper output in the year of his survey was estimated at 16,000–20,000 picols, valued at approximately 216,000 Spanish dollars at the prevailing price of 12 dollars per picol. The text also documents failed commercial ventures—sugar manufacture, gambier production, and indigo cultivation—all abandoned because the high cost of labour rendered them unprofitable relative to imported goods.
Ridley’s introduction, though brief, performs important editorial work: he identifies the locality of the Company’s spice gardens at Ayer Hitam for the first time with certainty, reconstructs the career of Christopher Smith (appointed botanist 1794, sent to Amboyna 1796, appointed Superintendent of the Botanic Gardens 1806, died c. 1806), and notes that the Government gardens founded in 1822 on the same site were sold cheaply by Governor Murchison in 1834. Ridley also flags that Hunter made numerous drawings referenced in the manuscript whose subsequent fate is unknown, and that several species could only be tentatively identified from Hunter’s descriptions alone.
Key Findings
- Christopher Smith sent from Amboyna in 1796 a consignment of 71,266 nutmegs and 55,264 clove plants, along with quantities of Canarium commune and Arenga saccharifera, which were established in the Company’s spice gardens at Ayer Hitam (p. 50).
- The island’s total pepper production in the year of Hunter’s survey was estimated at 16,000–20,000 picols; at the selling price of 12 dollars per picol, this represented a value of approximately 216,000 Spanish dollars (p. 66).
- A plantation of 46,000 three-year-old vines at Soongey Clooan yielded 500 catties of green pepper (175 catties dry) in a single day’s collection; the standard conversion was 100 catties green to 35 catties clean dry pepper (p. 65).
- The financial appendix projects that 100 Oorlongs (approximately 113 acres) planted with pepper would yield a clear profit of 153,000 Spanish dollars over twelve years at a conservative price of 10 dollars per picol, or 184,038 dollars when interest is computed at 12% (pp. 66–68).
- The height of Penang Hill was measured by Hunter at 1,192 feet, determined by triangulation from a 670-foot base using a three-foot reflecting telescope and object-glass micrometer (p. 53).
- A gambier plantation near Bato Lanshun was established by a Chinese planter but abandoned because the cost of labour exceeded the market price of imported gambier; the plants were uprooted and replaced with pepper vines (p. 73).
Conclusion
Hunter’s manuscript stands as the foundational botanical record of Penang’s colonial agricultural landscape, capturing the island at the precise moment when the East India Company was actively constructing its spice-garden infrastructure to challenge Dutch monopoly. Its enduring significance is twofold: it provides the first dated evidence of nutmeg and mangosteen fruiting in the Straits Settlements, and it documents the economic reasoning—both successful and failed—that governed early colonial plantation agriculture in the region.
Context
- Hunter wrote as a Company surgeon with direct administrative access to the spice gardens; his observations are those of a contemporary insider recording ongoing operations rather than a retrospective historian.
- The manuscript was preserved in the British Museum and edited for publication by Ridley, who added modern identifications in square brackets throughout; several of Hunter’s species remain unidentifiable even to Ridley.
