326 THE CANADIAN NATURALIST. [Sept, 



China. The best ore, from which is made the steel used in 

 manufacture of razors and other cutlery, is found in the 

 province of Shursi. 



The abundance and wide distribution of these invaluable 

 minerals offer the best facilities for the construction of machinery 

 of all kinds, and render railroads practicable as soon as there is a 

 government stable and strong enough to protect such property. ' 



Copper is found in many places in the north of China, and 

 large quantities have undoubtedly been taken out, and it is 

 probable that larger quantities yet remain. 



Tin is said to be found among most of the mountains of China, 

 though Prof. Bickmore had not seen a specimen in situ. If this 

 metal should prove to be as abundant as it is asserted on what 

 may be regarded as good authority, then Prof. B. thinks it will 

 be found that China, on account of the early age of her civiliza- 

 tion, has been the chief source whence came the tin that was 

 used by the Lake Dwellers in Switzerland in manufacturing their 

 bronze implements. Silver exists in the province of Shansi, 

 probably in great quantities. Gold is found in the beds of 

 nearly all the rivers in China, so long as they flow through the 

 mountainous regions. Prof. B. concluded his paper with these 

 words: — " In review, we see that China is well supplied with coal 

 and iron, the two minerals especially necessary for her future 

 development ; that these minerals are widely distributed over 

 almost her whole area, and that she has thus the requisite 

 materials for manufacturing her own cotton without being 

 dependent on the looms of England. Again, China possesses her 

 share of the precious metals, and yet nearly all her ample material 

 resources remain to be developed, though she has been the most 

 civilized nation in all the east, and the most populous empire the 

 world has ever seen." 



THE METAMORPHIC ROCKS OF NEW BRUNSWICK AND 

 MAINE. 



Prof. L. W. Bailey read a paper written by himself and Mr. 

 G. F. Matthew " On the Age and Relations of the Metamor- 

 phic Rocks of New Brunswick and Maine." 



The sediments to which the paper referred related chiefly to 

 those embraced in the most southerly of three spurs projecting to 

 the northeast from that extensive tract of altered and often 

 highly crystalline rocks which occupy the greater part of New
