black and orange on a white ground, and which were the most abundant
insects in the country lanes. Among these was a new species, which I
have named Pieris tamar.
Leaving Bileling, a pleasant sail of two days brought us to Ampanam in
the island of Lombock, where I proposed to remain till I could obtain
a passage to Macassar. We enjoyed superb views of the twin volcanoes
of Bali and Lombock, each about eight thousand feet high, which form
magnificent objects at sunrise and sunset, when they rise out of the
mists and clouds that surround their bases, glowing with the rich and
changing tints of these the most charming moments in a tropical day.
The bay or roadstead of Ampanam is extensive, and being at this season
sheltered from the prevalent southeasterly winds, was as smooth as a
lake. The beach of black volcanic sand is very steep, and there is at
all times, a heavy surf upon it, which during spring-tides increases to
such an extent that it is often impossible for boats to land, and many
serious accidents have occurred. Where we lay anchored, about a quarter
of a mile from the shore, not the slightest swell was perceptible, but
on approaching nearer undulations began, which rapidly increased, so as
to form rollers which toppled over onto the beach at regular intervals
with a noise like thunder. Sometimes this surf increases suddenly during
perfect calms to as great a force and fury as when a gale of wind is
blowing, beating to pieces all boats that may not have been hauled
sufficiently high upon the beach, and carrying away uncautious natives.
This violent surf is probably in some way dependent upon the swell of
the great southern ocean and the violent currents that flow through the
Straits of Lombock. These are so uncertain that vessels preparing to
anchor in the bay are sometimes suddenly swept away into the straits,
and are not able to get back again for a fortnight.
What seamen call the "ripples" are also very violent in the straits,
the sea appearing to boil and foam and dance like the rapids below
a cataract; vessels are swept about helplessly, and small ones are
occasionally swamped in the finest weather and under the brightest
skies.
I felt considerably relieved when all my boxes and myself had passed in
safety through the devouring surf, which the natives look upon with some
pride, saying, that "their sea is always hungry, and eats up everything
