Trin DEposits IN QUEENSLAND. 
The reports issued by the Geological Survey of Queensland, 
under the charge of Mr. Robert L. Jack, must prove of very great 
value to Australians, particularly to mining men, as, certainly, they 
are very instructive to their antipodal readers who are interested in 
geological work or the history and nature of the different mineral 
horizons. The reports, as read by us, are all written in a peculiar 
style, but it is extremely simple and succinct, and the many items 
of fact or detail are given in a manner very direct and concise, as 
all reports should be, each sentence being skorn of every unneces- 
sary word. 
The wonderful richness of the Australian mines, and the great 
area of mineral lands, are well known; it would seem as if men’s 
wildest dreams had been surpassed in their realization by the vast 
wealth of precious metals and priceless gems that has poured forth 
so bountifully from the natural treasuries of this wonderful land. 
Realizing the importance of as complete knowledge as possible of 
the different mining fields, of the geology of each district, with 
the exact conditions and relationships of the ore deposits with refer- 
ence to the enclosing or neighboring rocks, the reports of this sur- 
vey would indicate that its chief endeavors had been spent in 
examining and reporting upon the different mining districts, 
explaining the geological formations, and giving the results of the 
mining operations up to date. Such reports, with their accom- 
panying maps, must be a very useful and reliable source of infor- 
mation to all mining men, who, we believe, must look upon the 
work of Mr. Jack and his associates as being well done and of great 
practical benefit. 
Reading over the reports from the different fields, issued last 
year, we were much interested by that one on the tin 
deposits and their mining, in the Coolgarra District. The rocks 
consist mostly of altered vertical greywackes, quartzites and 
shales, flanked on the east by lofty granite ranges, there 
being no sharply defined boundary line between the granite 
and the sedimentary rocks, except that the latter have become 
more flinty and felsitic. Throughout the locality, are dykes
