Summary:
JDH thanks George Bentham for taking over from [Jules Émile] 'Citoyen' Planchon on Niger Flora. At Darjeeling JDH enjoys assistance from Brian Houghton Hodgson[BHH] & Müller; the latter is a Calcutta [Kolkata] Mint accountant. Pending approval from the Rajah JDH will travel more. JDH describes his daily routine whilst travelling & collecting with his Lepcha assistants, also describes his camp, challenges of difficult terrain, the scenery & his curiosity about the old roads. You cannot stray from the road as in the Alps & Andes. Bhutan & Upper Assam are closed to travellers & the low areas are unhealthy. JDH describes an unknown Sonneratia tree & mentions new Michelia & Cucurbitacea. JDH has published papers for the Asiatic Society. He wants to study the geography & natural history of eastern Himalaya as it has been ignored except by BHH. Botanically it can be divided into tropical, temperate & arctic areas. He describes the vegetation in Sikkim province: the area bounded by Kinchin [Kanchenjunga] & Teesta River, & compares it to that of Bhutan & Nepal. The description discusses: tropical jungle, conifers, Taxus, Pinus longifoli, P.deodara, P.pindrow, P.excelsa, P.smithiana, wild Cupressus, Brunonia, larch, palms, Cycas, Pandanus, Cruciferae, Ranunculus, Saxifraga, Primula, Oak, Magnolia, Lauri, Abies brunoniana, A. webbiana, Rhododendron, dwarf Juniper, tropical genera at unusual heights, pepper, Ficus, Calamus, Licualia, Wallichia, India-rubber fig, lack of open sward & European genera, pine forests, lack of legumes except Parochetus, Erythrina & different elevations at which characteristic vegetation appears. JDH discusses the climate of Sikkim & its influencing factors: the South East Monsoons & the Khasya & Behar Hills. Enmann’s Travels make JDH want to see Siberia & Chinese Tartary [Soongaria]. JDH also mentions: Edgeworth; Falconer going to Moulmein; Thompson, the deputy opium examiner at Patna; Crawford; Winterbotham in Tibet, Wallich & an Irish lady.
