PENDULUMS can be of almost any shape and, within reason, any size. Personally I use one not unlike a miniature mason’s plum-bob, about the size of a small hen’s egg and weighing just under two ounces. For ordinary purposes they should be made of wood or ebonite, in fact of any material that is a non-conductor of electricity. My Italian friend used a gold one:, quite small, about the size and shape of an acorn. Needless to say, that was not the one he gave me to practice with, which was of ebonite, but I now find it a little too heavy so I prefer wood. It is essential that the pendulum is black or dull in colour. Metals and bright colours are not suitable as they may produce special effects by acting as “samples” instead of the medium between the operator and the “sample”. Hollow pendulums are used for special purposes, being filled with a small quantity of the substance sought, such as oil or gold.

The string or thread must be pliant and strong: I use fine fishing line, about fifteen inches long with a small bone ring at one end to prevent it slipping through my fingers. I have seen all manner of things used as pendulums, all serving the purpose equally well; it is the person using the thing that matters, not so much the pendulum itself, although I have read of one Radiesthetist who used over a thousand different types.

The pendulum by itself can do nothing, you have only to suspend it from some inanimate object to prove this: it will remain stationary even if a railway engine is placed under it, but once it comes in contact with the human hand a piece of metal no larger than a pin’s head will bring it to life. The pendulum will do one of four things: 1, remain stationary; 2, swing or oscillate; 3, gyrate in a clockwise direction; 4, gyrate in an anti-clockwise direction. Under certain conditions it will move in an ellipse.


In order to get results Radiesthesia must be approached with enthusiasm and optimism; this is very important because the mental condition of the operator has considerable bearing on the result of his or her experiments. If the subject is treated halfheartedly nothing useful will be achieved and is better left alone as it will only be a waste of time and money.

In order to get the fundamental principles of this science you must try to imagine yourself, the operator, as a super-sensitive receiving set, as in fact you are. It is common knowledge that the volume from an ordinary wireless set can be increased by holding one end of the aerial. This surely proves that the human body can and does receive waves or radiations from the ether. Similarly in Radiesthesia you receive radiations from outside sources which you instinctively pass on, through reflex muscular action, to the pendulum, which, by its movements, enables you to perceive and measure the external influences you are, quite unwittingly, receiving. The pendulum may be regarded as ancillary to the sense of Touch as compared with the microscope in relation to the sense of Sight; it serves as an amplifier, but like the pendulum, requires suitable conditions and arrangement to be efficient.

The conditions under which experiments are made are very important, but before I give some of the more important I want you to accept from me, as a fact, that all objects, both animate and inanimate, give off radiations which, if the objects are sufficiently close to you, you will pick up, albeit unintentionally, thereby giving you mixed and possibly useless and baffling results.

In view of what I have just said it will be obvious that experiments should not be undertaken in a room full of people or on a table on which there is any large object which might influence you; for example, a sewing machine, tools, knives, etc. Nor should they be undertaken when the operator is unwell, or under the influence of alcohol, however slight, or during a thunderstorm when atmospherics are likely to be strong; nor should the operator wear rubber-soled shoes, as they will act as insulators. So much for the conditions, now for the arangement. The operator should be seated at a wooden table, preferably facing towards the West, with both feet firmly on the floor or ground (not cross legged). Assuming that he is right handed, the pendulum should be suspended from the right hand, the twine being held between the thumb and first finger, with the right elbow resting on the table, to give stability. The left hand should be on the table and may be either holding, or pointing at, the subject matter or “sample” as it is generally called. The arms and body of the operator now resemble a horseshoe magnet, the hands being the positive and negative poles; or perhaps a better comparison would be to a receiving set which, in fact, it is. The stage is now set for operations, but before commencing it is advisable to carry out a self -test of your sensitivity so as to avoid disappointment later on.

Testing for Sensitivity

There are several methods, all equally good, but the one I am going to describe has the added advantage of being self-applied and therefore allows of periodical checks at various times and under various conditions. Stand erect, facing due West, relax as much as possible, place the left hand over the solar plexus, palm inwards with the fingers closed. Suspend the pendulum from the right hand, using the full length of the twme, so that the pendulum is opposite the centre of the left hand and about 8 inches from it. The pendulum will commence to gyrate in a clockwise direction. Count the number of gyrations carefully, and if the gyrations are weak and less than fifteen your chances of getting any reliable results from Radiesthesia are remote and I suggest you go no further with it.
