Thomas Routledge opens his 1875 pamphlet by asserting that bamboo, among all fibre-yielding plants, is uniquely suited to meet the paper trade's demands. He supports this with specific growth rates: at Syon House, Bambusa Gigantea stems reached 60 feet in 12 weeks; at Kew, Bambusa Vulgaris grew three feet in a week. These measurements, attributed to named gardens and botanists, ground his argument in observable data rather than general praise.

Routledge identifies a key obstacle: previous attempts to make paper from bamboo failed because the plant was harvested when mature or over-mature, resulting in dense, indurated fibre. He implies that timing of harvest is as critical as the plant's natural properties, a technical insight that shapes his subsequent recommendations.

Growth Rates and Global Distribution

Routledge marshals evidence of bamboo's extraordinary growth from multiple locations. At Gehzireh, the Khedive of Egypt's gardens, it grew nine inches in a single night. At Chatsworth, Bambusa Vulgaris reached 40 feet in 40 days. These figures are not merely impressive; they serve to demonstrate the plant's potential for rapid, renewable fibre production.

He then catalogues bamboo's range: East Indies, West Indies, Central and South America, Brazil, Africa, Asia, China, Japan. The plant is indigenous to many regions and cultivated carefully in China and Japan for diverse uses. Routledge emphasizes that wherever heat and moisture exist, some bamboo species can be found or cultivated, suggesting a virtually unlimited supply for paper-making.

Botanical Classification and Fibre Extraction

Routledge divides fibre-producing plants into two botanical classes: Endogens (inside growers) and Exogens (outside growers). Bamboo, along with grasses, reeds, and sugar cane, falls under Endogens. He lists numerous examples—Manilla Hemp, Aloe, Sisal Hemp, Esparto—to contextualize bamboo within a broader taxonomy.

He then describes the labour-intensive extraction process for Endogenous fibres: stems are crushed, beaten, macerated, scraped, and combed, often by hand. Some plants are buried in wet sand or mud to rot, which weakens the fibre. The yield is only 6–12 per cent, and the process is only economical where labour is cheap. This technical detail underscores the challenge of industrializing bamboo fibre production.

The Paper Trade's Raw Material Crisis

Routledge surveys the paper trade's reliance on various fibres, noting that England's colonies and dependencies offer an inexhaustible supply of fibre-producing plants. He cites historical precedents: China, Japan, and India have long made strong, tough paper from raw indigenous virgin fibres, though not in a European style.

He references Dr. Forbes Royle's The Fibrous Plants of India and Dr. J. Forbes Watson's paper to the Society of Arts, grounding his argument in contemporary scientific authority. The implication is clear: bamboo, properly harvested and treated, could solve the paper trade's raw material shortage, but only if industrial methods replace traditional hand labour.

Routledge's pamphlet is a technical argument rooted in specific measurements, botanical classification, and economic context. Readers should attend to how he uses growth data not as spectacle but as evidence of bamboo's industrial viability. His critique of past failures—harvesting mature plants—offers a lens for evaluating his proposed solutions. The work is best approached as a period piece in industrial advocacy, revealing how 19th-century inventors thought about raw materials, labour, and global supply chains.
