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.
Sometimes the dry season was the hindrance; more frequently residence in a town or village not close to virgin forest, and surrounded by other houses whose lights were a counter-attraction; still more frequently residence in a dark palm-thatched house, with a lofty roof, in whose recesses every moth was lost the instant it entered.

This last was the greatest drawback, and the real reason why I never again was able to make a collection of moths; for I never afterwards lived in a solitary jungle-house with a low boarded and whitewashed verandah, so constructed as to prevent insects at once escaping into the upper part of the house, quite out of reach.
After my long experience, my numerous failures, and my one success, I feel sure that if any party of naturalists ever make a yacht-voyage to explore the Malayan Archipelago, or any other tropical region, making entomology one of their chief pursuits, it would well repay them to carry a small framed verandah, or a verandah-shaped tent of white canvas, to set up in every favourable situation, as a means of making a collection of nocturnal Lepidoptera, and also of obtaining rare specimens of Coleoptera and other insects.

I make the suggestion here, because no one would suspect the enormous difference in results that such an apparatus would produce; and because I consider it one of the curiosities of a collector's experience, to have found out that some such apparatus is required.
When I returned to Singapore I took with me the Malay lad named Ali, who subsequently accompanied me all over the Archipelago.
