It is scarce even here, as I did not see more than a dozen specimens in all, and had to follow many of them up and down the river's bank repeatedly before I succeeded in their capture.

When the sun shone hottest, about noon, the moist beach of the pool below the upper fall presented a beautiful sight, being dotted with groups of gay butterflies--orange, yellow, white, blue, and green--which on being disturbed rose into the air by hundreds, forming clouds of variegated colours.
Such gorges, chasms, and precipices here abound, as I have nowhere seen in the Archipelago.

A sloping surface is scarcely anywhere to be found, huge walls and rugged masses of rock terminating all the mountains and enclosing the valleys.

In many parts there are vertical or even overhanging precipices five or six hundred feet high, yet completely clothed with a tapestry of vegetation.

Ferns, Pandanaceae, shrubs, creepers, and even forest trees, are mingled in an evergreen network, through the interstices of which appears the white limestone rock or the dark holes and chasms with which it abounds.
