It is generally easy for a boy to get hold of a set of old clockworks, for a discarded clock of some sort is almost certain to be found in the household storeroom. If the main-spring is intact, it is highly probable that a little tinkering and cleaning will be sufficient to put the mechanism in working order, at least so that it can be used for running small engines, automobiles, and other mechanical toys that most interest boys.

Before taking a set of works apart, it is well to examine it carefully and note the positions of the various springs and wheels, so it will be possible to put them together again properly should you wish to do so. Without taking notice of this, you are likely to have a handful of wheels as a result, with which you can do nothing except perhaps convert them into tops.
