LORETO  , an inland See also:

department of See also:Peru, lying E. of the Andean Cordilleras and forming the N.E. See also:part of the See also:republic . Extensive territories, nominally parts of this department, are in dispute between Peru and the neighbouring republics of See also:Brazil, See also:Colombia and See also:Ecuador (see PERU), and the See also:northern and eastern boundaries of the territory are therefore not definitely determined . Loreto is bounded W. by the departments of See also:Amazonas and See also:San See also:Martin (the latter a new department, with an See also:area of 30,744 sq. m., taken from Loreto, lying between the central and eastern Cordilleras and extending from the 6th to the 9th See also:parallels, approximately), and S. by See also:Huanuco and See also:Cuzco . The area of the department, including the territories claimed by Peru, is estimated at 257,798 sq. in . The See also:population is estimated (1906) at 120,000 . The aboriginal population is not numerous, as the thick, humid forests are inhabited only where lakes and streams make open spaces for sunlight and See also:ventilation . With the exception of the eastern Andean slopes and a little-known range of See also:low mountains on the Brazilian frontier, called the See also:Andes Conomamas, the See also:surface is that of a thickly wooded See also:plain sloping gently towards the Maranon, or Upper See also:Amazon, which crosses it from W. to E . There are open plains between the Ucayali and Huallaga, known as the See also:Pampas del See also:Sacramento, but otherwise there are no extensive breaks in the See also:forest . The See also:elevation of the plain near the See also:base of the Andes is 526 ft. on the Ucayali, 558 on the Huallaga, and 453 at Barranca, on the Maranon, a few See also:miles below the Pongo de Manseriche . The eastward slope of the plain is about 250 ft. in the 62o m . (See also:direct) between this point and Tabatinga, on the Brazilian frontier; this not only shows the remarkably level See also:character of the Amazon valley of which it forms a part, but also the sluggish character of its drainage . From the S. the See also:principal See also:rivers traversing Loreto are the Ucayali and Huallaga, the former entering from Cuzco across its See also:southern boundary and skirting the eastern base of the Andes for about four degrees of See also:latitude before it turns away to the N.E. to join the Maranon, and the latter breaking through the Eastern See also:Cordillera between the 6th and 7th parallels and entering the Maranon 143 M. below Yurimaguas, where See also:navigation begins .

The See also:

lower Ucayali, which has a very tortuous course, is said to have 868 m. of navigable channel at high See also:water and 620 m. at low water . See also:North of the Maranon several large rivers pass through Peruvian territory between the See also:Santiago and Napo (see ECUADOR), nearly all having navigable channels . On the level plains are a number of lakes, some are formed by the See also:annual floods and are temporary in character . Among the permanent lakes are the Gran Cocama, of the Pampas del Sacramento, the Caballococha—a widening of the Amazon itself about 6o m . N.W. of Tabatinga—and Rimachuma, on the north See also:side of the Maranon, near the lower Pastaza . The natural resources of this extensive region are incalculable, but their development has been well nigh impossible through lack of transport facilities . They include the characteristic See also:woods of the Amazon valley, See also:rubber, nuts, See also:cinchona or Peruvian bark, medicinal products, See also:fish, fruits and See also:fibres . The cultivated products include See also:cocoa, See also:coffee, See also:tobacco and fruits . See also:Straw hats and hammocks are manufactured to some extent . The natural outlet of this region is the Amazon See also:river, but this involves 2500 M. of river navigation from See also:Iquitos before the ocean is reached . Communication with the Pacific See also:coast cities and ports of Peru implies the See also:crossing of three high, See also:snow-covered ranges of the Andes by extremely difficult trails and passes . A rough See also:mountain road has been constructed from Oroya to Puerto See also:Bermudez, at the See also:head of navigation on the Pachitea, and is maintained by the See also:government pending the construction of a railway, but the distance is 2 ro m. and it takes nine days for a See also:mule See also:train to make the See also:journey .

At Puerto Bermudez a river steamer connects with Iquitos, making the distance of 930 M. in seven days . From See also:

Lima to Iquitos by this route, therefore, involves 17 days travel over a distance of 1268 m . The most feasible route from the department to the Pacific coast is that which connects Puerto See also:Limon, on the Maranon, with the Pacific See also:port of Payta, a distance of 410 m., it being possible to See also:cross the Andes on this route at the low elevation of 6600 ft . The See also:climate of Loreto is hot and humid, except on the higher slopes of the Andes . The See also:year is divided into a wet and a dry See also:season, the first from May to See also:October, and the See also:average annual rainfall is estimated at 70 in. though it varies widely between distant points . The See also:capital and only See also:town of importance in the department is Iquitos .
