Extract

In work on responses of insects to sound at Belleville, by Mr. G. Wishart, a mechanical device was needed to provide a means of slowly revolving a pair of directional light-traps in a horizontal plane on the circumference of a circle 20 feet in diameter. One of the traps was to be used as an experimental trap and the other as a check against the results of the first. A machine was designed, constructed, and put into operation in July, 1961.
