De Vlaming notes in his journal that odoriferous wood was found on the mainland. Portions of it were subsequently submitted to the Council of the Dutch East Indies at Batavia, and from these portions an essential oil was obtained by distillation. It may well be supposed that this experiment was the first in the manufacture of eucalyptus oil, which, however, in our day is obtained not from the wood but from the leaves of the tree. On the 13th of January De Vlaming records that a dark resinous gum resembling lac was seen exuding from trees.
In a narrative of the voyage published under the title Journaal wegens een Voyagie na het onbekende Zuid-land, we read that on the 11th of January nine or ten Black Swans were seen. In a letter from Willem van Oudhoorn, Governor-General of the Dutch East Indies, to the Managers of the East India Company at the Amsterdam Chamber, it is stated that three black swans were brought alive to Batavia, but died soon after their arrival.[1]
Several boat expeditions were made, and Swan River was entered and ascended. During these expeditions the author of the Journaal mentions that the song of the 'Nachtegael' was heard. There are no nightingales in Australia, but the bird to which the writer of the Journaal alludes may have been the Long-billed Reed Warbler, the Australian representative of the Sedge Warbler and a denizen of the reed-beds of the Swan River. Two species of geese are also mentioned by the same writer under the names of European geese. It is somewhat difficult to determine to which geese the author of the Journaal alludes under the names 'Kropgans' and 'Rotgans.'
When English-speaking Dutch are asked to translate 'kropgans,' they do so by 'Christmas goose' or 'fat goose.'
