THE CUB A R E \' 1 1-: W 



must in a long run have an enervating in- 

 fluence on physical energy and will jjower : 

 to take these people, and after holding 

 them down for four years under a stun- 

 ning cataract of ordinances and reforms, 

 to present them with a republic and a con- 

 stitution, and expect them to work it on a 

 Ijasis of universal suffrage — this, surely, 

 is a proceeding" such as only our own su- 



l)lime age of faith in machinery cimld 

 have conceived or witnessed. 



"Penally," says the writer after discuss- 

 ing the graft charges so generally i)re- 

 valent, "the taint of corruption will have 

 to go much further than it has yet ad- 

 vanced in Cuba before it begins to rot the 

 body politic. Tt is a danger, but not a 

 menacing one." 



SECRET OF THE MAINE REVEALED 



It is probable that the examination of the 

 •wreck of the battleship "Maine'" will be 

 •completed by the end of this month. All 

 examinations to November 4th strongly 

 confirm the findings of the Sampson Board 

 that the ship was destroyed by an exterior 

 ■explosion, for sections of the bottom and 

 sides of the forward part have been found 

 to be lifted up and reversed by a tre- 

 mendous exterior force. Officers in charge 

 are, however, silent as to these conclu- 

 sions. 



The building of a wooden bulkhead 

 amidship was begun early this month and 

 there is no doubt that the after half of 

 the ship can be floated out. 



A large quantity of tmexploded 10-inch 

 ■shells were found in the shellroom, which 

 is still buried deep in the mud. 



Onh- a small amount of excavation is 

 now necessary to permit a complete interior 

 examination of the bow section, but the 

 principal interest attaches to the explora- 

 tion of the bottom and sides in the imme- 

 diate vicinity of the forward magazines. 



the ore in Cuba was of a low grade, as 

 expenses of handling it and w-ashing it u^as 

 too great. ( See frontispiece illustration, 

 showing the great lifting ])ridges.) 



MINERAL OUTPUT OF CUBA 



According to U. S. Consul R. E. Hola- 

 <lay at Santiago de Cuba, there was in- 

 creased activity in the mining operations 

 of the eastern district in 1910, as is shown 

 by the increase in exports of both iron and 

 copper ores. Several new iron mines were 

 also discovered on the north coast of Cuba 

 in the vicinity of Aloa, near the extreme 

 eastern end of the island. The mining 

 industries of the jirovince are owned by- 

 American iron and steel corporations. 

 Within the next few years the output will 

 xmquestionably be largely increased. The 

 plant of the Pennsylvania Steel Co. and its 

 •affiliated interests at Felton, or Nipe Bay, 

 has been completed, and the company ex- 

 ported last year from its mines at that 

 place 132,222 tons of raw ore and 166,699 

 tons of nodulized ore, a total of 298,921 

 tons, valued at $619,848. The plant has a 

 ■capacity of handing over 1,000,000 tons of 

 t)re per annum. 



No manganese was mined in 1910 because 



General Emilio Nunez, 

 Would former governor of Havana 

 Not Province, denied recently 



Accept that President Gomez had 

 offered him the post of Cu- 

 ban minister to ^Mexico. He would not 

 accept it if offered, he says, because of the 

 work which he is engaged in at present, as 

 the president of the National Council of 

 Veterans. 



On October 27th Secretary of State 

 Sanguily stated that the posts of Cuban 

 ministers to ]\Iexico and to PloUand, which 

 are vacant at present, would not be filled 

 for the time being. 



CATALOG NO. 50 



The Cuba Review has received the latest 

 catalog of the Jeffrey ^Manufacturing 

 Company, of Cohnubus, Ohio, on Power 

 and Transmission. There are more sub- 

 jects listed and more technical and real 

 information in this publication than in any 

 other of its class. Condensation has made 

 the book half the size of other books on 

 this subject although even at that there 

 are 142 pages of matter valuable to the 

 engineer in charge of an industrial plant, 

 mine, mill or factory. 



Besides listing dimensions and sizes of 

 every part of pow-er and transmission 

 machinery, there is 'descripti\e matter on 

 the Horse Powers and Steel Shafting, 

 Standard Methods of Key Seating, Sizes 

 and Dimensions of Couplings, Hangers, 

 Pillow, Blocks, Counter Shafts, Belt 

 1 ighteners. Clutches and, Quills. 



A feature is made of the Jeft'rey Im- 

 proved Split Iron Pulley, which may be 

 readily clamped on the shaft without dis- 

 turbing any other equipment, or may easily 

 be removed from the shaft when necessary. 



There are quite a number of details in the 

 last part of the book, including H. P. of 

 belts, method of calculating bending and 

 torsional moments for shafts, which are 

 invalualile to the engineering fraternitv.
