252 The N.Z. Journal of Science and Technology. [July 
of Wellington, and supposed to be identical with the Indo-Pacific form 
0. australis , belong to this species. Three new Astrophiurids are briefly 
described : Astroporpa wilsoni and Astroschema elegans from near the North 
Cape, and Astrotoma benhami off the Three Kings. Ophiocreas eonstrictum, 
previously recorded from the West Coast Sounds of the South Island, was 
also taken off the Three Kings. H. F. 
The Australian Forestry Journal. 
This new quarterly journal is issued by the New South Wales Forestry 
Commission at a subscription of 2s. per annum. The editorial to the first 
number, signed by Hon. W. G. Ashford, Minister for Lands and Forests, 
clearly indicates the scope of the journal: “ The Forestry Journal is not 
intended to be a technical publication, burdened with highly scholastic 
articles and bristling with the phraseology of science, which is little under¬ 
stood by others than the scientists. On the contrary, it is intended to be 
understandable by all people ; to be instructive to ‘ the man in the street ' 
no less than informative and interesting to those for whom forestry is a 
profession and a business. Briefly, the idea is to put before the public 
periodical bulletins of notes and news which shall cause those who read 
to recognize that forestry is worth while that trees are deserving of 
attention, care, and respect.' 1 
The first two numbers are full of interesting matter, and illustrated 
with good views of forests, and augur well for the success of the journal. 
The Government of New South Wales is to be congratulated on its favour¬ 
able attitude to scientific forestry. 
Metallurgical Reports, Department of Mines, South Australia. 
Government Departments tend to run in grooves and to imitate one 
another in different countries. There is little reason why nearly all countries 
should possess a Geological Survey and not a Chemical or Natural History 
Survey, but it is so. The South Australian Department of Mines is to be 
congratulated on departing from ordinary ways of Mines Departments 
by appointing a Government Metallurgist and instituting a series of metal¬ 
lurgical reports. The first report deals with the recovery of copper from its 
ores in the United States by leaching and precipitation, and on appliances 
used in connection therewith, and cannot fail to be of great service to the 
copper-mining industry of the State. The second report deals also mainly 
with the metallurgy of copper, but there is a short note on the milling of 
barytes at Aldgate, which will be of interest to those contemplating the 
development of this mineral in New Zealand. 
The Active Volcanoes of New Zealand, by E. S. Moore. Journal of 
Geology, vol. 25, 1917, pp. 693-714; two maps and eleven photographic 
illustrations. 
Professor Moore visited New Zealand after the Australian meeting of the 
British Association in 1914, and this paper is a result of his visit. 
The most valuable parts of the paper are notes of original observations 
on Ruapehu, Ngauruhoe, and Tongariro, a detailed account of the Tarawera 
area with an account of the eruption of 1886, and a section on the petro¬ 
graphy of the Tarawera rocks. The occurrence is noted of peculiar bombs 
with a core of rhyolite and an enveloping coat of andesite or basalt. They
