In my opinion, what constitutes the faculty of divination is an inherent quality that cannot be acquired. Some people describe it as a sixth sense, while Dr. Grasset, a French authority, believes that the ability to find underground streams proves the existence of a faculty belonging to a class of psychological feelings forming what he calls "psychisme inferieur," the study of which is just beginning to attract the attention of the scientific world.
Perhaps I should explain that, as a rule, a forked twig, the extremities of which are held loosely in each hand, is used to locate sub-artesian water, and in this connection its movements, so far as is known, can only be affected by natural running streams. The rod, or twig, does not work if carried over water passing through drains, culverts, and such like. My explanation of the movements of the rod is that they are caused by electro-magnetism, the diviner being perhaps highly charged with electricity. The water has absorbed the electricity of the adjacent bodies in the earth, the currents coming to the surface enters the air—ether—and the currents entering his body, he being a non-conductor, agitates him. Most people are conductors, consequently the current passes through them, and they do not feel it. The electric twig in the hands of the diviner forms a part of the connection between the body and the water, and by a law of nature, these two bodies must either attract or repel each other. If the experimenter is a person with a small amount of the electric fluid in his nature, that is negatively charged, the water being positive will draw down or attract the twig, hence the downward movement. If on the other hand, he is surcharged with electricity, or positive, the positive electricity of the water will repel the other, and the twig will bend upwards. The movements of the twig may thus be accounted for, but, comparatively, so little is known or understood of the marvellous influences and workings of electricity that it is impossible to be dogmatic on the question.

The forks of the twig should be held lightly between the second and third fingers of the hands, pressing the thumbs on the side of the twig with just sufficient force to give the ends a slightly-outward direction. If a person possesses the faculty, and water flows anywhere beneath him, the twig will turn round on its ends between his fingers. In my own case, should I hold the twig tightly over a natural underground stream, it will bend under and round in an endeavour to follow out the movement I have just mentioned. It will, perhaps, be interesting to know that now I only use the twig for the purpose of indicating the presence of streams. The faculty is so sensitive in my hands that I can detect water if I am 20 yards away. I have found by careful observation and study that I can far more effectively decide upon the actual bore site by the indications which my hands give. Holding them downwards, open, and with the palms facing, I have found that as I approach the strongest, and therefore the most suitable, point in the stream for boring, they are thrust forcibly apart and upwards by the same power, apparently, that acts upon the twig. I found this out in a peculiar manner. After marking a site with the twig, I happened to place my hands together, and to my surprise they came up, and I could not keep them together.
I must say it was only by accident that I discovered my possession of this faculty. About 1906, a water diviner visited the Winton district, and one day several friends and myself went with him in his quest for water. He explained his methods to the party, and naturally we all provided ourselves with twigs.
After living so many years in the dry, western country, I was, of course, very interested in the experiment, and closely following directions was astonished after walking about for some time to find my rod revolving slowly. Members of the party near at hand were equally astonished, and called loudly to the others to "come and look at Corfield's twig." They, thinking it was due to the twig alone, soon ruined it, but I felt that I was possessed of some power, which previously I did not know I possessed, as I knew I was not turning the stick myself. For about twelve months after that I closely studied every phase of the phenomenon, and during that time I discovered good water for many residents in the district.
In 1907, an opportunity came to me to employ my faculty for the benefit of pastoralists and the State generally.
Mr. R. C. Ramsay, of Oondooroo Station, invited me to ascertain if good water was obtainable in a dry belt of that country, and in this I was entirely successful.
It is an interesting fact that I do not require to leave a vehicle by which I may be travelling in order to carry out my search for water. Whilst seated in a train, or motor car, travelling at the rate of 30 or 40 miles an hour, I have by means of the rod located streams. If it were not that the currents were in the air, as I have previously referred to, I should be insulated by the India-rubber tyres of the motor.
