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
the table, while many would fly up to the roof and give me a chase
all over the verandah before I could secure them. In order to show
the curious connection between the state of weather and the degree
in which moths were attracted to light, I add a list of my captures
each night of my stay on the hill.

Total 1,386
It thus appears that on twenty-six nights I collected 1,386
moths, but that more than 800 of them were collected on four very
wet and dark nights. My success here led me to hope that, by
similar arrangements, I might on every island be able to obtain an
abundance of these insects; but, strange to say, during the six
succeeding years, I was never once able to make any collections at
all approaching those at Sarawak. The reason for this I can pretty
well understand to be owing to the absence of some one or other
essential condition that were here all combined.
