Among the various improvements brought forward from time to time in the Billiard world, are those having for their object, the secure fastening of the tip to the point of the cue. The very latest idea in this direction is that of hollowing out the top of the cue, inserting a thin spiral spring and fastening the same securely, about a couple of inches from the top, by means of a brass pin. The tip, upon the same principle as an ordinary boot button, is made to attach to the loose end of the spring inside the cue, and by this means kept securely in position. The idea is that of a gentleman well known in Leeds, and we are informed that all the best players in that City now have their cues fitted in this style.
