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.
