GUERRERO  , a Pacific

coast state of Mexico, bounded N.W. by Michoacan, N. by Mexico (state) and Morelos, N.E. and E. by Puebla and Oaxaca, and S. and W. by the Pacific . Area, 24,996 sq. m . Pop., largely composed of Indians and mestizos (1895), 417,886; (1900) 479,205 . The state is roughly broken by the Sierra Madre and its spurs, which cover its entire surface with the exception of the low coastal plain (averaging about 20 M. in width) on the Pacific . The valleys are usually narrow, fertile and heavily forested, but difficult of access . The state is divided into two distinct zones—the tierras calientes of the coast and lower river courses where tropical conditions prevail,and the tierras templadas of the mountain region where the conditions are subtropical . The latter is celebrated for its agreeable and healthy climate, and for the variety and character of its products . The principal river of the state is the Rio de las Balsas or Mescala, which, having its source in Tlaxcala, flows entirely across the state from W. to E., and then southward to the Pacific on the frontier of Michoacan . This river is 429 M. long and receives many affluents from the mountainous region through which it passes, but its course is very precipitous and its mouth obstructed by sand bars . The agricultural products include cotton, coffee, tobacco and cereals, and the forests produce rubber, vanilla and various textile fibres . Mining is undeveloped, although the mineral resources of the state include silver, gold, mercury, lead, iron, coal, sulphur and precious stones . The capital, Chilpancingo, or Chilpancingo de los Bravos (pop .

7497 in 1900), is a small

town in the Sierra Madre about rro m. from the coast and 200 M . S. of the Federal capital . It is a healthy well-built town on the old Acapulco road, is lighted by electricity and is temporarily the western terminus of the Interoceanic railway from Vera Cruz . It is celebrated in the history of Mexico as the meeting-place of the revolutionary congress of 1813, which issued a declaration of independence . Chilpancingo was badly damaged by an earthquake in January 1902, and again on the 16th of April 1907 . Other important towns of the state are Tixtla, or Tixtla de Guerrero, formerly the capital (pop . 6316 in 1900), 3 M . N.E. of Chilpancingo; Chilapa (8256 in 1895), the most populous town of the state, partially destroyed by a hurricane in 1889, and again by the earthquake of 1907; Iguala (6631 in 1895); and Acapulco . Guerrero was organized as a state in 1849, its territory being taken from the states of Mexico, Michoacan and Puebla .
