1866. | Mining, Mineralogy, and Metallurgy. 423 
Our notices of mining operations in other countries must neces- 
sarily be brief. A considerable degree of excitement has been 
ereated in relation to mining in California, and not a little, especially 
in America, in connection with the development of the wonderful 
Lake Superior district. 
By the courtesy of the proprietors, we have been favoured with 
copies of the ‘American Journal of Mining,’ published in New York. 
This new periodical, embracing “Milling, Oil-boring, Geology, 
Mineralogy, Metallurgy,” &c., has a sufficiently expanded field tor 
its labours. Within the United States territory, nearly every 
metalliferous and earthy mineral has been found. The extent of the 
American coal-fields is vast, and roads and railways are rapidly 
opening out districts from which the supply of fuel can be 
abundantly obtained. A new industry has been created in the oil 
regions, and the rapidity with which the iron manufacture of the 
United States is expanding, shows that such a journal as that 
now before us, if conducted with strict honesty of purpose, must 
become important, equally to the miner, the metallurgist, the manu- 
facturer, and the public. The ‘American Journal of Mining’ 
evidently takes the ‘ Mining Journal’ of this country as the example 
it would follow. Reports on mines and mining, correspondence on 
these, on metallurgy and mineral manufactures, with notices of 
these sciences which bear upon any of those industries, and a very 
extensive share-list, form the bulk of the papers yet issued. 
Amongst the original papers, those on “ Petroleum,” by 
Professor Francis E. Engelhardt, promise to be as valuable and 
instructive, as they are interesting. From the “ Mining Statistics,” 
by Dr. Ki. P. Stevens, we abstract the following particulars relative 
to several branches of mining and metallurgy :— 
The rapid increase of mining and metallurgical works in 
America are a striking proof of the rapid development of those 
important industries in that great continent. 
We find it stated in United States’ official documents that there 
are now 157 mining establishments engaged in raising iron ore, 
employing 3,177 men. ‘There are 97 bloomaries, 286 furnaces, 
256 rolling mills, 16 mills for drawing iron wire, 17 car-wheel 
manufactories, 1,412 establishments for castings, 19 for locomotives, 
74 for sewing-machines, 239 for arms, 443 for hardware, 382 for 
steel, 99 for nails, 154 for scythes, and 14 for printing-presses. 
Copper.—There are 42 mining establishments in Michigan, 
New Mexico, Tennessee, and North Carolina, producing 499,534 
tons of ore. 
Coal.—In round numbers the production is stated at 15,000,000 
tons. In our last, we gave it from a strictly reliable source as 
14,593,659 tons. The collieries employ 36,469 workmen. 
Lead and Silver.—Lead mining and smelting are stated to have
