The town of Sarayacu is situated on a small creek, about three miles
from the place on the river which is called the Puerto del Sarayacu.
Between Pucacura and Sarayacu is Esquina, a small settlement built on
high land, which extends along the river for a mile or more. This
place (Esquina) and Pucacura are about the only places on the banks
of the Ucayali, below Sarayacu, that are not overflowed at high water.
The floods of the Ucayali, which regularly recur every year at certain
seasons, render the banks of the river an undesirable, perhaps even an
impracticable, location for an agricultural population. It is possible
that a crop might be raised and gathered during the dry season, but
the farms would have to be abandoned whenever the river rose to its
maximum height. At Paca, about twelve miles above Sarayacu, the banks
on both sides of the river are high; such places are much more
frequently met with above than below Sarayacu, but still they are the
exception to the general character of the country near the river,
which continues to be low and subject to overflow until the highlands
are reached near the confluence of the Tambo and Urubamba.
