The banks of the Ucayali and Pachitea, at their confluence, are low, subject to overflow and unsuitable for settlement. About nine miles above its mouth we come to the first Indian village on the Pachitea, a male Conebo hamlet, with nothing to recommend it except that it is situated on ground a little higher than the flats which surround it. On the left bank of the Ucayali a few miles below the mouth of the Pachitea, there is a place called Hoje, which is not subject to overflow at high water, but in other respects it is not an eligible position for a town or post. The Pachitea is navigable at low water for steamers drawing nine feet of water to the confluence of the Palcazu and Pichis rivers.

MOUTH OF THE PACHITEA.

Latitude, 8° 43' 30" south; longitude, 74° 32' 30" west of Greenwich; magnetic variation, 8° 45' 40" east; thermometer, 75°; elevation above sea-level, 508 feet; distance from the Atlantic, 2891 miles; current, 3 miles per hour; width of the Pachitea at its mouth, 400 yards.

CUÑUYACU.

Latitude, 9° 5' 52" south; longitude, 74° 48' 15" west of Greenwich; magnetic variation, 8° 59' 26" east; elevation above sea-level, 557 feet; distance from the Atlantic, 2951 miles; current, 2-1/2 miles per hour; width of the river, 400 yards.

Cuñuyacu means hot water, and is descriptive of the place, for there are here several thermal springs welling up from the sand beach. At Chunta Isla, between the mouth of the Pachitea and Cuñuyacu, the Cashibo Indians frequently attack from ambush strangers who are ascending the river.

INCA ROCA.

Latitude, 9° 9' 4" south; longitude, 74° 55' 45" west of Greenwich; magnetic variation, 8° 6' 26" east; distance from the Atlantic, 2963 miles; current, 2-1/2 miles per hour.

Inca Roca is a rocky beach overhung by sandstone cliffs sixty-five feet high; on the face of the cliffs are carved numerous figures, amongst them the figure of the sun and of the Llama are conspicuous, hence the place was named Inca Roca.
