ECONOMIC GEOLOGY 
Gold . — Alluvial gold has been worked in the Islands of Saint Aignan and 
Sudest, and is known to exist also in Normanby Island, in the Vanapa River, and in the 
Saint Joseph District. In Normanby Island the gold is associated with cinnabar. Reefs 
are worked on a small scale in Sudest Island, and have been noted in Normanby 
Island. In the years 1888 to 1891, inclusive, 8,399 oz. of gold, valued at £31,310, have 
been reported to the Customs at Cooktown, from New Gruinea.* 
Sulphur . — Native sulphur occurs in Rergusson and Goulvain Islands, in the 
D’Entrecasteaux Group. 
Lignite . — Seams of lignite are known in Yarn Island, and on the Ely and 
Strickland Rivers. 
Mercury . — Cinnabar has been found in small quantities at Merani, in Cloudy 
Bay, and in Normanby Island.

* “That gold exists in the western and northern portions of New Guinea has long been known ; that 
it exists also on the south-eastern shores of that great island is equally true, as a specimen of pottery 
procured at Redsear Bay contained a few laminar grains of this precious metal. The clay in which the gold 
is imbedded was probably part of the great alluvial deposit on the banks of the rivers, the mouths of which 
we saw in that neighbourhood, doubtless originating in the high mountains behind, part of the Owen 
Stanley Range.”— MacGillivray. Narr, Votjage ofH.M.S. “ SaUlesmUe,” &c., 18S2, ii., p. 69,
