Railway Signals.—An effective communication from the guard to the engineman, for the prevention of railway accidents, seems to be an important desideratum, which has hitherto baffled the ingenuity of philosophers. The only proposed plan likely to be adopted, is that of a cord passing below the foot-boards, and placing the valve of the steam whistle under the control of the guard. The trouble attending this scheme, and the liability to neglect and disarrangement, render its success doubtful. What I humbly suggest is, that the guard should be provided with an independent instrument which would produce a sound sufficiently loud to catch the ear of the engineman. Suppose, for instance, that the mouth-piece of a clarionet, or the windpipe of a duck, or a metallic imitation, were affixed to the muzzle of an air-gun, and the condensed air discharged through the confined aperture; a shrill sound would be emitted. Surely, then, a small instrument might be contrived upon this principle, powerful enough to arrest the attention of the engineer, if not equal to the familiar shriek of the present whistle.

It is hoped that this hint will be followed up; that your publication will sustain its character by thus providing a medium of intercommunication for these worthies, who can respectively lay claim to the titles of men of science and men of letters, and that some experimenter "when found will make a note"—a stunning one.

A Centenarian Trading Vessel.—There is a small smack now trading in the Bristol Channel, in excellent condition and repair, and likely to last for many years, called the "Fanny," which was built in 1753. This vessel belongs to Porlock, in the port of Bridgewater, and was originally built at Aberthaw in South Wales. Can any of your readers refer to any other trading vessel so old as this?
