566 RECORD OF MEETINGS OF THE 



The coal was compared with that from other localities in 

 which the benches show notable difference in volatile. The 

 results of tests with caustic potash made upon a number of 

 coals appeared to show that non-coking coals are attacked 

 promptly, while coals yielding a firm coke Sre not affected 

 even after prolonged boiling. The speaker promised to give 

 at a future meeting the results of an extended series of tests. 



The paper was discussed by Professor Kemp and others. 



The last speaker was Professor Kemp, who discussed new 

 sources of the supply of iron ores. Emphasis was first placed 

 upon the enormous demands made by the iron industry of 

 to-day upon the mines of the United States, Great Britain, 

 and Germany. The conviction was held by many that within 

 fifty years the local American sources of rich ores, of whose 

 existence we now know, would be exhausted and the iron 

 masters would be compelled to seek new deposits. The follow- 

 ing possible new districts were passed in review: the Labrador 

 prospects discovered by Mr. A. P. Low of the Canadian Geologi- 

 cal Survey, which might also ship to Europe; Adirondack 

 areas of reported magnetic attraction and possible lean ores; 

 the Temagami district and the Michipicoten range, Ontario; 

 the southern continuation of the Marquette range beneath the 

 drift ; the southern half of the Mesabi probable syncline beneath 

 the swamps northwest of Duluth, as suggested by C. P. Ber- 

 key; the Baraboo range; the deposits in Iron County, Utah, and 

 in the Wasatch Mountains; the magnetites of southern Califor- 

 nia and the prospects in Washington and along the coast. The 

 speaker emphasized the important reserves in the titaniferous 

 magnetites and their great quantity. 



Passing to Europe the new developments in Sweden at 

 Gellivara and Kirunavaara were reviewed and the possibilities 

 at Routivaara; also the Dunderland valley in Norway and the 

 similar deposits farther north. Their relations to the smelting 

 centres in Great Britain and Germany were explained and 

 their comparative amount with the "minette" ores of France, 

 Luxemburg, and Germany brought out. Other deposits in 

 Spain, Algiers, Venezuela, India, Australia, and Shan-si in 

 China were mentioned.
