=Magdalena=, adjoining the Peninsula, is a Department a great part of which is low and hot. The inhabitants include many Indians, a friendly tribe on the Sierra Nevada. Back of these mountains are rich valleys, where white settlers have been disturbed by savage Indians who live on the lower slopes of the East Cordillera. Among the products of the region are coffee, cocoa, sugar, and bananas. The upper valleys are the better settled and cultivated; mineral wealth including petroleum is evident. Santa Marta, the capital, an ancient city and port, founded 1525, has recently entered upon an era of prosperity, largely due to the enterprise of the United Fruit Company. Finely located on a good harbor west of the Nevada of Santa Marta, some distance east of the mouth of the Magdalena, the city is an important centre of the banana industry, to which it owes its present development; other agricultural products are for local consumption. The climate is hot but healthful, though the banana zone is malarial. An excellent hospital is maintained by the United Fruit Company. Within a few miles are regions with a delightful temperature. A Marconi wireless, one of the most powerful in South America, is of general service, though the property of the Fruit Company. Their enormous banana trade is served by a 100 mile network of railways into sections favorable to this fruit. =Atlántico= is a small Department occupying the flat hot delta of the Magdalena River. Barranquilla, the capital, is a busy place with many resident foreigners. It has quays, a large new warehouse, hotels, one of which is said to have all conveniences, theatres, two clubs, electric lights, trams, and telephones. In spite of the heat, which averages 82° for the year, the deaths are less than 25 per 1000, a percentage better than in some other tropical cities. =Bolívar= follows, a very large Department, with the Magdalena River for its eastern boundary. Bolívar like Atlántico has vast plains suited to tropical agriculture and to cattle raising, now a growing industry. The great natural resources of forest, agriculture, and mineral products are but moderately developed. The breeding of horses, donkeys, and mules is a profitable business followed by many. Ten gold mines are worked. Cartagena, the capital, is considered the most interesting city on the Caribbean coast and one of the most picturesque in South America. Its massive walls and fortifications were erected at great expense nearly four centuries ago--1535. It has fine buildings both ancient and modern, and comfortable hotels. Montería and Lorica are busy commercial cities on the Sinú River, each with a population of 20,000 or more.
