did not urge him, but after several hours of walking, he
was again asked to mount, and he did so, thereby seeming to understand
what was required of him.

When they camped at noon for the first meal, they were still on the
banks of the Cataract, but here it took a decided turn to the west; and
now the course for the afternoon must be to the southwest so the South
River could be reached above the falls.

That river was reached early in the afternoon, and they recognized the
trail formerly made on the first journey along its banks. The first
encampment for the night was probably twenty miles from home, but the
next morning, after they had struck into an entirely new section of the
island, the journey grew more burdensome, as the land on both sides of
the stream became rough, and in many places the small streams crossed
offered such steep sides that frequent detours had to be made to enable
the team to get across.

During the second day they did not, on account of this, cover more than
ten miles, and near the close of the day a second falls was reached,
showing that they were going up to a much higher altitude. Above the
falls the river turned abruptly to the south, and within five miles of
it the river forked, one branch going south and the other southwest.

They were on the branch going west, and that course was followed, but
still the country was rough, and now became thickly wooded, which added
to the discomfort of traveling with a team. Magnificent trees grew on
every side, and in most places sprang up clear to the water's edge.

"You have here a good illustration," remarked the Professor, "as to the
source of the debris which is found on the shores of the island. The
streams carry down the logs, trees and leaves, which, after being washed
out to sea, are finally left along the beaches."

Our voyagers had passed many nights in the forests before, but this was
the first time they had come across such impenetrable jungles. The large
trees were actually so close together at many places that the wagon had
to be backed and worked around for long distances to enable them to make
any forward movements.

Before noon of the third day it became so discouraging that they stopped
to consider the situation. Possibly a route away from the river would be
much better, and that course was decided on, so that the direction
agreed on was west, with a slight trend to the north.

The reason why the course along the river would be
