The navigation of the Pichis was found to be clear and unobstructed
from its mouth for a distance of fifteen miles up to Rochelle Island,
which is in latitude 9 deg. 57' 11" south, longitude 75 deg. 2' 0"
west of Greenwich, and three thousand one hundred miles from the
Atlantic coast, following the course of the Amazon river. Rochelle
Island was reached on the 7th of June, and was named after Captain
James Henry Rochelle, the senior member of the Commission. Any
steamer which can navigate the Pachitea can ascend the Pichis this far
without difficulty, but above Rochelle Island the navigation becomes
more difficult, and probably impracticable for any but steamers of
very light draught and strong steam power.

On the 15th of June the expedition arrived at the head of canoe
navigation on the Pichis. The point was named Port Tucker, after the
president of the Commission. Port Tucker is in latitude 10 deg. 22'
55" south, longitude 74 deg. 49' 0" west of Greenwich, distant three
thousand one hundred and sixty-seven miles from the mouth of the
Amazon, following the course of the river, and one hundred and ninety
miles in a direct line from the Pacific coast. The lofty mountains so
plainly in sight from Port Tucker are the eastern spurs of the Andes,
the chosen land of the savage and numerous Campas Indians.

Several days before the expedition reached the shoals which terminate
the navigation of the Pichis, the tom-toms or drums of the Campas were
heard night and day beating the assembly of the warriors. The purpose
for which the braves were to be assembled was not a matter about which
there was the least doubt, but probably sufficient numbers were not
got together in time to execute their intentions, for no attack was
made on the Commission whilst it was in the Campas country.

During this expedition the Palcazu river was also ascended to Port
Prado, or Puerto del Mairo, the head of navigation for steamers of
light draught. Port Prado is in latitude 9 deg. 55' 22" south,
longitude 75 deg. 17' 45" west of Greenwich, distant three thousand
one hundred and nineteen miles from the mouth of the Amazon, following
the river, and only about forty miles from the important interior city
of Huanaco, to which place it is in contemplation to extend the
trans-Andean railway. If the road were continued from Huanaco to Port
Prado there would be a complete trans-continental line of
communication by railway and steamboats from Lima in
