At the junction of the Palcazu and Pichis, the two rivers forming the
Pachitea, there is high land suitable for a town or post.

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 deg. 55' 22" south; longitude, 75 deg. 17' 45" west of
Greenwich; thermometer, 75 deg.; 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.

PICHIS RIVER.

The Pichis is a branch of the Pachitea river. The Cashibos and Campas
Indians inhabiting its banks are warlike tribes and fiercely oppose
all attempts to examine their country. Nothing was known of the river,
above its mouth, until it was explored and surveyed, in 1873, by the
Peruvian Hydrographical Commission of the Amazon, accompanied by a
military escort. It was necessary for the Commission to bestow names
on notable places as they proceeded to discover them, and these names
were afterwards used in making the chart of the river.
