PALACAZU RIVER.
The Palacazu is a somewhat narrow stream, with a current of 3-1/4 miles per hour and a depth which at low water will permit a steamer drawing seven feet of water to ascend to Puerto del Mairo.
PUERTO DEL MAIRO.
Latitude, 9° 55' 22" south; longitude, 75° 17' 45" west of Greenwich; thermometer, 75°; elevation above sea-level, 795 feet; distance from the Atlantic, 3119 miles; current, 3-1/2 miles per hour.
Puerto del Mairo is 45 miles distant from the large city of Huanaco, which has constant communication and trade with Lima. At present the route between Huanaco and Puerto del Mairo is only a footpath through the forest, but it is probable that a good road for pack-mules could be constructed at little expense, and that a railway is not impracticable.
