Thus oil aud upward the road winds; until, ' having reached an elevation of 15,64s1 feet, it- passes' tho summit through a tunnel 3000 feet long, aud emerging on the eastern slope, winds down to ;La Oroya, on the Atlantic side of tho Cordillera. ; In this great work engineering science has smoothed down the ruggedness of nature, and man has.triumphed over matter. The tunnel cuttings reach au aggregate length of over three miles, ami there aro 30 bridges and viaducts, besides innumerable cul verbs. The road will opeh a way for the ■ products of the agricultural region lying on the eastern' Blopo of the' Aud.es to the seaboard cities of Peru, and also affords means for;the rich mineral deposits lying in the district between San Mateo i and the Summit to be davolopcdV whioh :their isolatedness has heretoforp precluded. Already trains run boyoud Lurco, Tho road-bed is in part laid up to the Summit tunneL aud on the slope ' that leads down to La Oioya. It is expected that 15 or IS months moro will suffice to complete tho road, and tho former toilsome, ■•■ dangerous, and'wearying journey of a week will be reduced to the easy jaunt of a day. Tho road is ft Governmeut enterprise, 'and belongs to the nation-of Peru, the work being performed under contract by Henry : Meigfs, the llailroad King of South America. Although ~b.ut .136 .nxilc3. long, the road has caused a groat expenditure of, labour and life, the latter-partly'from! a reckless use of ,i spirituous liquors,- aiid partlyby fevers pro vailing in a narrow belt of territory.
