HOW ON MINEEALS FOR THE PARIS EXHIBITION. 27 



6. A column of coal from Albion Mines, Pictou Co., in the 



name of G. M. A., ( — Hudson, Agent.) Dimensions, 

 37ft. 10 inches in height. 



7. Oil coal (and oil) from Albion Coal- Fields, in the name of 



J. W. Jackson, Esq. 



It is needless to say that a display of such massive samples 

 of coal, which are accompanied in some cases by plans of work- 

 ings and statements as to quality, must produce a very striking 

 eifect. 



IRON ORES, OR PRODUCTS. 



Ores, pig iron, bars, and cutlery, by the Acadia Charcoal 

 Iron Co., Londonderry. 



Brown hematite iron ore, from Brooktield, by W. Barnes, 

 Esq. 



Brown hematite and specular iron ore, by J. B. Oxley, Esq. 

 I am not acquainted with the last named iron ores, but the 



others are very similar in appearance and no doubt in quality. 



They are very pure and rich ores. The quality of the iron and 



steel afforded has been proved with the Acadia ores, and is 



well known to be of a very high order. The Brookfield ore I 



have analysed for the proprietors, and it gave — 



Abater, 11.36 



Silica and firansfue, 1.54 



Phosphoric acid, trace 



Magnesia, trace 



Peroxide of iron and a very little alumina, 87.10 



100.00 

 results which show it to be a very pure and rich ore. 



THANGANESE ORES. 



Pyrolusite, from Teny Cape, by J. D. Nash & Co. 

 Pyrolusite, from East Mt. Onslow, by Robert Murray, Esq. 



The Teny Cape manganese ores are now well known as 

 among the richest and purest 3'et found in the world. The 

 average per centage of manganese, in the best samples, will 

 probably be at least 90 per cent. The Onslow ore looks very 

 good, and will no doubt give a high per centage of manganese.
