over the hatches of vessels. One of these bridges carries a 15-ton trolley and grab for 

 handling ore, and the second a 6-ton grab to be used mainlj^ for unloading coal, but also 

 available as an auxiliary ore carrier. The nodulized ore in the stock yard is delivered 

 to and taken from a trough with inclined sides, which facilitates the pick-up with the 

 grap buckets. For the mechanical details above given, the writer is largely indebted to 

 data prepared by James E. Little of the Pennsylvania Steel Co., of which the Spanish- 

 American Iron Co. is a subsidiary. 



The operations of the Spanish-American Iron Co. at Diaquiri are carried on at a 

 distance of about 5 miles from the coast, shipments being made to Santiago harbor by 

 rail. These consist of mining the ore in benches, with the aid of Bucyrus steam shovels, 

 and crushing it in Allis-Chalmers gyratory breakers of the Gates type. The system of 

 mining, and the crushing and loading plants, are so clearly shown by the accompanying 

 illustrations that none of the details will be entered into here. 



The mines of the Juragua Iron Co., a subsidiary of the Bethlehem Steel Co.. are lo- 

 cated at Firmeza, abo'ut 17 miles east of Santiago, to which port the ore is also con- 

 veyed by rail for shipment, like all of the other ores mentioned, to the United States. 

 The particulars of this operation will be given in a later article. 



Of greater immediate interest, because of the loading problem that was solved, is the 

 property of the Ponupo Manganese Co. at Nima Nima, about 9 miles west of Santiago. 

 At the time this mine was opened only 250,000 tons were in sight, and the cost of 

 building a railroad to connect with the nearest harbor, Santiago, w-as deemed prohibitive ; 

 but about 3 miles distant from the mine was the open roadstead of Xima Xima, where 

 vessels could lie close to the rocky shore. 



Output of the Mines 



The following tabulation of the output of the iron mines now operating in Cuba, since 

 the opening of the first mine in 1S84, might be of interest :

1912, record year for Daiquiri and Mayari IMines and for Cuba. 



1913, record year for Juragua Mines. 



It is evident from the above figures that Cuban iron mining was not only in a healthy 

 condition during 1913, but that it was the best year in its history with the one exception 

 of 1912, which is likely to hold the record for some time to "come. — Letter of D. B.
