Not illustrated. 1907 edition. Excerpt: ...ores, from the Lake Superior district, for the season of 1906, was $4.25 at Lake Erie ports. The average charges are estimated as follows: Mining, 85c; rail freight to lake, . $1; lake freight, 75c.; taxes, 5.5c.; interest, 2c; royalty, 40c; total, $3,075. This leaves a net value of $1.75 per ton at the mines. The prices of Mesabi ores averaged $0.25 below those of Old Range ores. The large demand was followed by an increase in prices, and toward the end of the season higher prices were made on the small quantities not covered by season contracts. A higher price was also fixed as a base for 1907. While this advance in the base price of Lake Superior iron ores, was from 50 to 75c. per ton, it was really greater than that, owing to a lowering of the guaranteed iron content. The accompanying table shows the base guarantees for 1907, as compared with those for the current year. Under these conditions, the actual increase in price to furnacemen is 90 to 95c. for bessemer ores, and 60 to 65c. for non-bessemers. Pig Iron. The statistics collected by the American Iron and Steel Association give the production of pig iron in the United States in 1906 at 25,307,191 long tons, the greatest output ever reported, and considerably more than that of Germany and Great Britain combined. Comparing 1906 with the previous year, it is seen that foundry and forge iron showed a decrease in 1906 of 122,682 tons. All other classes showed increases: bessemer, 1,433,402 tons; basic, 913,495; charcoal, 80,079; spiegel and ferro, 10,517 tons. The total gain was 2,314,811 tons, or 10.1 per cent. The most marked proportional change was in basic iron, which increased 22.3 per cent., while the gain in bessemer pig was 11.6 per cent. Foundry and forge irons lost 2.1 more
