 THE MINNESOTA COPPER MINE, IN 1859
 This is the richest worked copper mine in the Lake Superior copper region The stock of the company is divided into 10000 shares, on each of which $3,50 has been paid in. They are now worth $l20 each. In other numbers, the original investment of $7O,000 has now value of $2,400,00O i-' :.
 The net profits divided amongst the stock holders during the first years, from 1852 to l957 amounted to $980,OO0, showing repro duction of l4 times the original investment THE CERRo PAsCo SILVER MINES, | Are situated in Eastern Peru, about llO south of the line. These mines were discover ed in 1881. According to Lieut. Herndon, U. s. Navy, the ore is quarried in monster pits, open cuts, and is very poor; but the facilities for procuring at little expense large quantities, and their easy amalgamation, makes the work ing of them profitable. The principal mass of the extracted ores yield but about l6 ounces to the ton.
 According to Mir. Castleman, these mines produced up to l849, the enormous sum of $475, ,0O0, ,0OO, which would give an annual aver age of $2, l70,000. The annual average is now only estimated at $2,OOO000. Cerro Pasco is situated on the Eastern slope of the Andes, al an elevation of some $500 feet above the sea, and have populati0d ofabout 1000 souls.
