worked with some activity in I860, and abandoned in 1865, has 

 just been reopened, and workings are commenced with the promise 

 of a thorough examination, and it is hoped of a satisfactory result. 

 This mine is stated to produce native antimony, sulphide of anti- 

 mony, or glance antimony, and the grey and red ores of this metal. 



Mr. J. G. Williams, of Aberystwith, who has for many years 

 been connected with the Lead mines of Cardiganshire, especially 

 those which are in the Gogerdan property, has just published an 

 interesting little work, called ' A short Account of the British En- 

 campments lying between the Eivers Eheidol and Llyfnant, in the 

 county of Cardigan, and their connection with the Mines.' Mr. 

 Williams has instituted a careful examination of a considerable 

 number of ancient encampments He finds some to be, as he con- 

 siders, peculiarly British, others being Boman, or Boman- British ; 

 and their positions prove unmistakably that they were con- 

 structed for the purpose of protecting the mines adjoining them. 

 Wherever there is a group of mines, Mr. Williams finds a group of 

 encampments also. This is really a valuable contribution to the 

 obscure history of early British Mining. 



In connection with publications relating to Mining, we may 

 state that we have seen the advanced sheets of a work ' On Gold 

 and Silver Mining and Metallurgy in all parts of the World.' It 

 is by Mr. John Arthur Phillips, a gentleman well known as the 

 author of a ' Manual of Metallurgy,' and for his extensive ac- 

 quaintance with the Mines of the Old and the New Worlds. The 

 book is extensively and beautifully illustrated. 



Dr. Clement Le Neve Foster, D. Sc, Lecturer to the Miners' 

 Association of Devon and Cornwall, has translated from the Dutch 

 Yan Diest's ' Banca, and its Tin Stream Works,' which is decidedly 

 the best account of this extraordinary stanniferous district which 

 has appeared. It cannot but be of the greatest importance to the 

 English Tin miners to know exactly the conditions under which 

 the Dutch obtain the tin in their Eastern possessions. The Banca 

 Tin being at the present time the most serious rival with which the 

 British Tin miner has to contend. 



Professor F. de Hochstetter has recently brought before the 

 Imperial Geological Institute of Vienna an account of several 

 * exploitations " . for coal and iron in the Banat. The coal 

 formation of Steierdorff, which was discovered in 1790, and which 

 belongs to the Lias formations, has within the last few years been 

 brought into notice. Five beds of coal have been worked upon, 

 and they give a yearly production of 165,000 statute tons. This 

 coal is known commercially as the coal of Orawieza, and is one of 

 the best produced in the Austrian Empire as regards calorific 

 power. Much of it is used for the steam navigation of the Danube, 

 and for locomotive purposes on some of the railways. Gas is
