The principal industry of the surrounding country is mining, and gold and silver are exported in considerable quantities . Coffee and hides are also exported, but the trade of the city has been greatly impeded by difficulties of transportation . A railway from Puerto Berrio, on the Magdalena, was begun many years before the end of the 19th century, but political 'and financial difficulties interposed and work was suspended when only 43 M. were finished . The completion of the remaining 8o m. was part of a larger scheme proposed in 1906 for bringing the Cauca Valley into railway communication with the national capital .
