JDH last wrote to his father, William Jackson Hooker, from Bay of Islands. Expedition omitted Chatham Islands & has been in open sea for 135 days but now nears Berkeley Sound, Falkland Islands. Before reaching an ice barrier they went to a record latitude south. Discusses Sargasso weed, seaweed propagating in open sea, e.g. Macrostaysis pyrifera, & implications for plant distribution. JDH will write to Ward re. New Zealand moss. Heard from Sinclair about WJH's move to Brick Farm House, that RBG Kew is to be a public park & that Balfour got the [botany] chair at Glasgow University not Arnott. Recalls that the Hookers were shunned by most Glasgow academics but he has fond wishes for some of their true Glasgow friends. Is glad James Mitchell is working for Lord Eastnor. Discusses publication of ICONES [PLANTARUM], Gardner's return to England, MONOGRAPH OF SOUTHERN FRAGI & a new sp. found by Bidwell. Describes distribution of Ballia brunoni in Kerguelen's Land & Auckland Islands. Discusses mosses of Campbell Island: new Sclotheimias, Holomitrion perichaetiale, & an Andreaea whose unusual structure he describes. Mentions a NZ Polytricha like Dawsonia, Sprengel's Maschalocarpus ciliatus, a new Hookeria from Van Diemen's Land [Tasmania] & endemic H. cristata. Pities Swainson going to NZ, explains the shortcomings of the colony & notes some disreputable emigrants: Baron Thierry, Mr Macdonnell & Mr Polack but praises the missionaries esp. Colenso. Letter continues dated 8 Apr [1842] with a description of East Falkland incl. birds: Cormorant, Cape Pigeon, Albatross & Cook's blue nosed petrel. Describes procuring skins of birds, but says he never lets ornithology overtake botany. Has some NZ shells for his sister, Maria Hooker. Hopes to go to Rio de Janeiro & collect Cryptogamia for Harvey. Reports landing at Port Louis, a mining town in a desolate landscape where the purser met with Governor Moody. Expects to be home 1843 after crossing D'Urville's Barrier in Weddell's track.

JDH writes to his father, William Jackson Hooker, to inform him of the expedition's movements & his own activities. He has previously sent WJH some drawings & a map showing the position of Mount Erebus. They did not stop at the Chathams so JDH could not send the live New Zealand tree ferns & pines, it being too costly for Captain Ross to pay freight via Sydney. JDH has collected many new moss & lichen species, but not many new plants. He has made extensive notes & drawings of the New Zealand flora & landscape. Mentions that the New Zealand Fagus is the same Birch found in the Straits of Magellan according to Vancouver's VOYAGE OF DISCOVERY TO THE NORTH PACIFIC OCEAN. Mentions a mistake in his notes re. the number of anthers in Oreobolus. In New Zealand JDH became good friends with Dr Sinclair via whom he sends a parasitic caterpillar fungus from Rev Taylor of Waimate. It was found near Yass on the Murrumbidgee River in New Holland [Australia] by John Allan who has also provided information, which JDH transcribes. JDH also recounts what he found out about the habits of Spheria robertsii, another fungus that uses Caterpillars as a host. The letter continues under date May 3 [1842] JDH having returned from a hunt. JDH is sending letters on the ship 'Arrow' via Rio de Janeiro to his family, Bentham, Dalton & the Bootts. He also intends to write to Ward & Brown. In the Falkland Islands he has collected: Balka Brunonii, new Cardamine, some Grasses, a Halorageous Kerguelen's Land plant, a Ranunculus. Andreae are common & other Mosses are in fruit. Discusses investigation of Tussac Grass [Poa flabellata], a remarkable species of Carex Governor Moody wants information about. A Mr Wright has been botanising in the Falklands & Wilmot has been relieved at the Cape. JDH sends best wishes to Captain Beaufort & the Sabines. The expedition is in need of supplies, JDH needs spectacles & packing paper & wants to hear about RBG Kew & [George] Gardner. Sends regards from McCormick.
