There is an article by Mr. T. T. Read on ‘‘Coal Mining in 
Manchuria”’. The Fushun Mines, north-east of Mukden, are worked 
in Tertiary strata, which yield a soft bituminous coal. The total 
thickness of coal varies from about 150 to 270 feet, made up apparently 
of many seams closely associated. ‘The greatest thickness without 
a parting is, 32 feet, but the five seams worked are each from 9 to 
12 feet thick. It is estimated that the production for 1909 may be 
- about 700,000 tons. Apparently the coal was worked in very early 
times for the manufacture of pottery, as in making excavations on the 
ground large quantities of ancient Korean pottery and coins dating 
back to 800 B.c. have been discovered. 
5. Grotocy oF Brisror.—A concise and interesting Sketch of the 
Geological History of the Bristol District, by Professors C. Lloyd 
Morgan and 8. H. Reynolds, has been published by the Bristol 
Naturalists’ Society (Proceedings, vol. ii, pt. ii, 1909). It contains 
references to the principal published works, and embodies accounts of 
the more recent researches on the Silurian rocks, the Carboniferous 
zones, and the origin of the physical features. 
6. GerotocicaL Survey or New Jersry.—The Annual Report of 
the State Geologist, Mr. H. B. Kiimmel, for the year 1908 (1909), 
contains an account of the zine mines of Sussex County, by Mr. A. C. 
Spencer. The ore minerals are principally franklinite, containing 
oxides of iron, manganese, and zinc; willemite, silicate of zinc, much 
of it containing manganese; and zincite, oxide of zine, also with 
manganese. Mr. J. V. Lewis contributes a report on the Building 
Stones, illustrated with map, views of old and new buildings, and 
coloured plates of various granites, serpentine, marble, and other rocks.

LIBRARY DURING THE YEAR ENDED DecemBer, 1908. 8vo. London 
(Geol. Soc.), November, 1909. Price 2s.—It is merely necessary to 
remind our readers that this valuable record of the geological work 
of the world is published for 19068. Mr. W. Rupert Jones, 
Mr. Belinfante, and Mr. C. H. Black have all contributed to the 
heavy task of getting it ready, and the publication fully maintains its 
position as the one indispensable work of reference for all geologists. 
An index of 76 pages to 113 pages of bibliography sufficiently 
indicates the exhaustive nature of the work and its utility.
