a Malay boy named Ali and stayed there three weeks for the
purpose of making a collection of land-shells, butterflies and
moths, ferns and orchids. On the hill itself ferns were tolerably
plentiful, and I made a collection of about forty species. But
what occupied me most was the great abundance of moths which on
certain occasions I was able to capture. As during the whole of
my eight years' wanderings in the East I never found another spot
where these insects were at all plentiful, it will be interesting
to state the exact conditions under which I here obtained them.

On one side of the cottage there was a verandah, looking down
the whole side of the mountain and to its summit on the right,
all densely clothed with forest. The boarded sides of the cottage
were whitewashed, and the roof of the verandah was low, and also
boarded and whitewashed. As soon as it got dark I placed my lamp
on a table against the wall, and with pins, insect-forceps, net,
and collecting-boxes by my side, sat down with a book. Sometimes
during the whole evening only one solitary moth would visit me,
while on other nights they would pour in, in a continual stream,
keeping me hard at work catching and pinning till past midnight.
They came literally by the thousands. These good nights were very
few. During the four weeks that I spent altogether on the hill I
only had four really good nights, and these were always rainy,
and the best of them soaking wet. But wet nights were not always
good, for a rainy moonlight night produced next to nothing. All
the chief tribes of moths were represented, and the beauty and
variety of the species was very great. On good nights I was able
to capture from a hundred to two hundred and fifty moths, and these
comprised on each occasion from half to two-thirds that number of
distinct species. Some of them would settle on the wall, some on
