The two substances known as “Tasmanite” and Australian “White Coal,” which are the subject of the present communication, have a special interest for the geologist on account of the light which they throw upon the microscopio structure and composition of many Coals. My attention was first directed to them when collecting materials for Professor Huxley’s examination into the microscopic structure of Coal. My esteemed colleague, Mr. Etheridge, at that time gave me a specimen of brown laminated substance, labelled “Lignite, the so-called White Coal, Australia,” and drew my attention to the fact that it was very largely composed of small seed-like bodies, very similar to, although smaller than, the macrospores of Flemingites, which are to be seen in many kinds of British Coal. A specimen of this same kind of White Coal is in the Museum of Practical Geology, and is labelled, “ Bituminous Shale (locally called White Coal), New South Wales, Australia.” I have likewise been able to examine the specimen of Tasmanite also in this Museum, which is labelled “ Tasmanite; combustible matter from the river Mersey on the north side of Tasmania; stratum of unknown thickness, but known to extend for some miles. Presented by Sir Won. Denison.” These specimens are very similar in appearance and structure, but the White Coal is softer than the Tasmanite. Chemical analyses of Tasmanite have been published, but I am not aware of any satisfactory account of ’its microscopic structure. The only mention of Australian White Coal with which I am acquainted is that in Prof. Huxley’s lecture on “On the Formation of Coal” (“Contemporary Keview,” Nov. 1870). And there is a figure, of a section and some separated spores, given by Sir C Lyell in the 2nd edition of his Student’s Elements of Geology, 1874.

The next appearance of the older lead is at the “Rocky-ridge,” where the river, after running northerly for three-quarters of a mile, along the strike of the metamorphic beds, turns abruptly to the west. This ridge is a basalt-capped hill on the north side of the river, running in a north-west direction; it is about a mile long, with a bold rocky escarpment on its west side, facing the Sandy or Cudgebeyong Creek. Some tunnels have been driven in, and shafts sunk on this hill, and tolerably rich deposits of gold were found, but never followed out.Only in the southern half of the hill have diamonds been found(all more or less spotted).The drift is remark-able for the number and size of the agates it contains.The northern half of “the ridge” is underlaid by another outlier of the before-mentioned doubtful purple conglomerate, into which some tunnels have been driven in the western escarpment.The basalt is merely a fringe here, resting against the flank of the conglomerate, in which a small quantity of nuggetty gold was obtained;and form one to two inches thickness of lignite, or carbonaceous clay, is seen between it and the bottom of the basalt. Tte basali is intersected by numerous veins of a mineral allied to kaolin. The purple con-glomerate is similar in character to that near “the flat”and contains, on some of the joint faces, smll spherical crystalline aggreations of chalybite(carbonate of iron).At the extreme north ead of “the ridge”are great quantities of ironstone and conglomerate, but, from their Carbpniferous series, which is largely developed further north.The first diamonds which found their way to Melbourne were obtained.


The material which forms the subject of the present communication was recently discovered at two different localities in New South Wales, and was received for investigation partly from Prof. Sir Edgeworth-David through Prof. A. C. Seward, F. R. S., partly from Mr. G. D. Osborne, Lecturer in Geology at the University of Sydney. The two localities are (1) near Mt. Tangorin, Hunter River District, (2) Lyndon, S. of Eccleston, Allyn River. The six specimens from the first locality were all found in situ by Mr. G. D. Osborne, in a fresh-water conglomerate belonging to the Kuttung Series of rocks, at an horizon at least 2,000 feet above the base of the series. The single specimen from the second locality was found as a loose pebble, but although the exact horizon is unknown the fossil probably also belongs to the Kuttung Series.

In a former Paper on Thylacoleo was summed up what I then inferred from the fossil remains of the species “ carnifex ” which had reached me at that date, but acquiescence in those conclusions seemed, in the opinion of some contemporary Palæontologists, to require further evidence. I have, accordingly, omitted no opportunity of obtaining such, and the fossils so acquired form the subject of the present communication. The locality which promised success in this quest was the limestone district of Wellington Valley, New South Wales, from one of the caves of which the first evidence of Thylacoleo had been obtained.

Inputs and losses from Giant Parramatta grass [GPG, Sporobolus indicus (L.) R. Br. var. major (Buse) Baaijens] soil seed banks were quantified on the North Coast of New South Wales. Monthly potential seed production and actual seed fall was estimated at Valla during 1991-92. Total potential production was >668 000 seeds/m2 for the season, while seed fall was >146000 seeds/m2. Seed fall >10000 seeds/m2.month was recorded from January until May, with further seed falls recorded in June and July. The impact of seed production on seed banks was assessed by estimating seed banks in the seed production quadrats before and after seed fall. Seed banks in 4 of the 6 sites decreased in year 2, although seed numbers at 1 damp site increased markedly. Defoliation from mid-December until February, April or June prevented seed production, reducing seed banks by 34% over 7 months. Seed banks in undefoliated plots increased by 3300 seeds/m2, although seed fall was estimated at >114 000 seeds/m2. Emergence of GPG seedlings from artificially established and naturally occurring, persistent seed banks was recorded for 3 years from bare and vegetated treatment plots. Sown seeds showed high levels of innate dormancy and only 4% of seeds emerged when sown immediately after collection. Longer storage of seeds after collection resulted in more seedlings emerging. Estimates of persistent seed banks ranged from 1650 to about 21260 seeds/m2. Most seedlings emerged in spring or autumn and this was correlated with rainfall but not with ambient temperatures. Rates of seed bank decline in both bare and vegetated treatment plots was estimated by fitting exponential decay curves to seed bank estimates. Assuming no further seed inputs, it was estimated that it would take about 3 and 5 years, respectively, for seed banks to decline to 150 seeds/m2 in bare and vegetated treatments.

About thirty years ago a species of manna, obtained from the Eucalyptus Mannifera, was brought from New South Wales, and was examined by Dr Thomas Thomson, and afterwards by Professor Johnston, both of whom ascertained it to contain a new species of sugar, different from the mannite which exists in ordinary manna. The author had, through the kindness of Mr Sheriff Cay, an opportunity of examining a very different species of manna, remarkable both from its chemical constitution, and from its possessing a definitely organised structure. This substance was discovered by Mr Robert Cay in 1844, in the interior of Australia Felix, to the north and north-west of Melbourne, where it occurs at certain seasons on the leaves of the Mallee plant, Eucalyptus Dumosa, and is known to the natives by the name of Lerp.

Russell Drysdale was an Australian artist who created an original vision of the Australian landscape from the 1940s to the 1960s, portraying the emptiness and loneliness of the Australian outback and country townships in his paintings, drawings, and photographs. During World War II, he depicted everyday subjects, including groups of servicemen waiting at railway stations. He traveled numerous times to the interior of Australia, including a trip to record the drought devastation in South Western New South Wales in 1944, where he created images that convey the environmental degradation of the landscape. In 1947, he explored the Bathurst region with Donald Friend where he discovered Sofala and Hill End, an area that served as the subject matter for his art for a number of years. Drysdale painted many images of deserted country towns as well as brooding landscapes peopled with stockmen and station hands. In his paintings of Aborigines, Drysdale expressed a deep concern for the Indigenous people, often placing them within his paintings in a manner that conveys a sense of dispossession. His work was singled out by Kenneth Clark in 1949 as being among the most original in Australian art, and his exhibition at the Leicester Galleries, London, in 1950 convinced British critics that Australian artists had an original vision.
