14 THE CUBA REVIEW dredged to a depth of 28 feet. The approach-channel, 2,500 feet long'-and 200 feet width, was dredged to the same depth. Felton, on Cagimaya Bay, a well-protected branch on the south side of Nipe Bay, close to its entrance, has proved a very safe and satisfactory harbor. Each year more investigations are made of the deposits beyond the mines opened, and the results confirm the statement that this and the Mayari beds contain fully 500,000,000 tons with an extensive area still unexplored. The tonnage available for steel making may be 600,000,000 or more, as only a half million tons or more of ore are mixed annually.—Henry Hale, in the Scientiftc American, New York. The Mining and Engineering World recently printed abstracts of discussions before the American Institute of Mining Engineers in February, 1912, on the valuation of iron mines for taxation. In the course of the proceedings comparisons were made of the Cuban ore vC^ith that of the Lake Superior mines, and Mr. E. E. White of Ishpeming, Mich., prepared a table of costs of nodulized Cuban ore, which is as follows: COST OF CUBAN ORE AT PITTSBURGH Cts. per Unit Mining, 27 cts. per ton, 40 cts. nodulized 0.76 NoduHzing, $1 per ton 1.89 1,200 miles sea-haul at 0.05'22 = 62.6 cts. per ton 1.19 25 miles land-haul in Cuba at 0.336 = 8 cts. per ton 0.15 328 miles land-haul to Pittsburgh at 0.336 = $1.10 per ton 2.09 Loading and unloading boats, 10 cts. per ton 0.19 Terminal costs in Cuba, 18 cts. per ton 0.34 Terminal costs in U.
