In May, 1918, a sample of graphite from Pakawau was forwarded to the 
Geological Survey by Mr. W. F. Worley, of Nelson. This consisted both 
of lumps and of fine material, and was in general of lustrous appearance, 
but some of the lumps were dull, and all were much harder than pure 
graphite would be. Part of the sample was analysed at the Dominion 
Laboratory, with the following results : Carbon, 32-6 per cent. ; water, 
0-5 per cent. ; ash, 66-9 per cent. Dr. Maclaurin states : “ The carbon 
appears to be intermediate in form between antharcite and graphite. It 
burns off too readily to be used as a stove-polish, nor does it appear to 
be suitable for lead-pencils. Experiments conducted with a view to con¬ 
centration did not give encouraging results, only a slight concentration 
being effected by panning.” 
Another portion of Mr. Worley’s sample, which included rather more 
of the better-looking material than that sent to the Dominion Laboratory, 
was submitted to the Morgan Crucible Company (Limited), Battersea, Eng¬ 
land. The following analysis has been supplied by the company in a letter 
dated 21st August, 1918 : Carbon, 39-2 per cent. ; volatile matter, 2-9 per 
cent. ; ash, 57*9 per cent. The graphite is reported as probably not saleable 
on the London market in the condition represented by the above analysis, 
and even if concentrated to 90 per cent, carbon would not be of much value, 
owing to its being in the non-crystalline form. 
24. WaJcamarama Range. —Cox states (p. 364) that in 1871 samples of 
graphite-shale were forwarded from Wakamarama by Mr. A. J. Burne. 
These samples were the same as those mentioned by Skey in Lab. No. 7, 
1872, p. 19, Nos. 1142/A, B, of which he gives the following analyses :—

According to the list on page 26 of the report cited, these samples were 
forwarded by Mr. Johnson from the Wakamarama Ranges. This gentle¬ 
man was probably the Mr. Johnson connected with several mining ventures 
in Nelson many years ago. 
25. North-west Nelson.— The last eight or nine localities mentioned are 
in north-west Nelson, but a few general remarks may be made. The 
schists and phyllites (“ slates ”) of this part of New Zealand are highly 
graphitic in many places. Cox speaks of bituminous schists in the Para- 
para district (Rep. Geol. Explor., No. 14, 1882, p. 44, &c.) ; McKay of 
bituminous schists and carbon slates in the Baton and Wangapeka dis¬ 
tricts (Rep. Geol. Explor ., No. 12, 1879, p. 124) ; Park of black graphitic 
slates (with graptolites) at Golden Ridge, Gouland Downs, Quartz Ranges, 
Kaituna Valley, &c., and of black slate passing into bituminous limestone 
south of the Parapara River (Rep. Geol. Explor., No. 20, 1890, p. 236) ; 
Bell, Webb, and Clarke of graphite schists near the mouth of the Boulder 
River, on the track to the Quartz Ranges, on the Anatoki River, and in 
Washbourn Block south of Parapara Inlet (Bull. No. 3, 1907, p. 42), and 
of graphitic phyllites at Silverstream, in Wakefield Gully, and at the head 
of the Paturau River (Bull. No. 3, p. 44). The last-named authors also 
mention that carbonaceous argillites are seen in Slaty Creek, in Fifteen- 
mile Creek, and at many other places in Aorere and Waitapu Survey Dis¬ 
tricts (Bull. No. 3, p. 44). They evidently include the black graptolite-
