Chapter 9 Chapter 9 The Prospecting Wand and the Prospecting Pendulum

In recent decades, geophysicists have invented many ingenious instruments for exploring the geological features of the subsurface.In the petroleum industry, for example, there is a seismometer that can determine the depth of different formations with considerable accuracy.It cannot prove the presence of oil, but it can find rock structures that may contain oil.Even so, Rikaku has yet to find any way to tell from the surface whether certain minerals (such as oil or water) are actually buried deep in the earth without actually drilling. Pseudoscience is not subject to such limitations.In this chapter we shall discuss two exotic instruments of prospecting, the prospecting wand and the magic pendulum, and briefly describe how to use them and similar novel methods of prospecting for oil (commonly known as "prospecting magic"). .

The so-called wand prospecting is to use a thin stick with a fork at one end to find groundwater sources or other substances.In this method, the prospector holds the rod tightly in each hand, with the forked end facing upwards.He walked across the surface of the pool, and suddenly the wand turned in his hand, as if moved by a powerful, unstoppable force.Sometimes the turning was so violent that the bark was peeled off by clenched fists.Wherever the wand points down, of course the water is to be found. A variety of woods have been used for prospecting wands, but hazel, peach, and willow seem to be more commonly used.Some wand prospectors also use other substances such as ivory, metal, wire, etc. for this work.A few warlocks, especially in India (local warlocks often receive salaries from local water conservancy bureaus), use only two empty hands.According to these unarmed prospectors, when they walked over the groundwater source, the palms felt as if they were shocked by electricity.The ability to prospect with a wand seems to be limited to certain people.Some of the most famous wand prospectors were illiterate and themselves completely baffled by their psychic powers, without any explanation.

The use of various styles of sticks for divination has existed as early as ancient Greece and Egypt.However, at that time people were limited to predicting the future, detecting criminals, and performing such magic.In the Middle Ages, many priests used sticks for divination, but it has been associated with the power of the devil.The use of a forked wand to find mineral deposits apparently only began when the Germans were prospecting in the Harz Mountains in the fifteenth century.The German miners who entered England in the sixteenth century brought this method with them.In England, the application of the wand has shifted from prospecting to finding water.

By the end of the seventeenth century, wand prospecting was widely used in England and throughout Europe, and scientists vigorously debated and opposed it. "Tell us, in the name of the Father, the Son, and the Holy Spirit, how far is this from the mine?" A formula like this is often used by wand prospectors, but the Church still opposes it. In 1659, the Jesuit elder Gaspard Short wrote a book denouncing the practice as heresy, but he later changed his mind and endorsed the theory that human muscles produce an involuntary movement.The famous seventeenth-century wand prospector, Baron Beaussolier, was accused of witchcraft and died in prison. In 1701, the Inquisition issued a decree prohibiting the use of divine rods in trials.

By the "Age of Enlightenment" of the eighteenth century, wand prospecting had become a common practice and was no longer considered a ghostly trick.William Barrett, professor of physics at the Royal Irish Academy of Sciences, made the first significant "scientific" study of this problem in 1891.Barrett and Theodore Bestman's present book, The Prospector's Wand, published in 1926.This is one of the leading reference books on the subject.The basic point of the book is that wand movement is due to an involuntary movement of the wand prospector's own muscles.These people have a special ability to sense where there is water.

From 1909 to 1943, Frenchman Henri Mager published a series of books on wand prospecting, which further developed the theory that wands were controlled by electromagnetic waves. , the English translation of the book "The Wand and Its Method" was published in 1931.In England, two members of the "British Association of Wand Prospectors", Sissel Maby and Bedford Franklin, conducted a series of experiments.Their 452-page book, "Physics with the Prospecting Wand" (1939), also held the same view, arguing that this phenomenon was caused by radio waves. While articles and books on prospecting for wands could be filled with lengthy tomes, there is one recent book that has been more important than any previous one.This is the 534-page monograph "Psychophysics" written by Dr. Solkol Trump, a professor of geology at Al-Fadh I University in Cairo.Written in English and printed in the Netherlands, the book was published in 1949 by the Elsville Publishing Company.

According to the bibliographic advertisement of the publishing house, Dr. Trump was born in 1909, received a doctorate in geology from Leiden University in the Netherlands in 1932, and became a professor at the University of France and Germany in 1947.He has conducted wand prospecting experiments in Leiden and Delft in the Netherlands.This research work convinced him that wand prospecting was a real phenomenon, caused by the electromagnetic fields surrounding subsurface material.He believes that this electromagnetic field acts on a similar electromagnetic field in the prospector's brain.His book contains hundreds of striking illustrations, tables, and diagrams, including a 25-page electrocardiogram recorded by electrodes in the wand prospector's hand.

The first half of Trump's lengthy book deals with the electromagnetic field in Earth's atmosphere, subsurface and around living organisms.Wand prospecting is the result of a certain interaction of these electromagnetic waves.Trump is convinced that a wand prospector can not only determine the location of subterranean material, but he can also determine a person's gender.The wand prospector stands on the left side of a reclining man and turns his wand over his head. If the prospector's right hand is higher than his left, the person is a man.If it is a woman lying down, then the left hand will be higher than the right hand.But some wand prospectors have high and low hands, which is exactly the opposite.One might think this would disprove Dr. Trump.Absolutely not.This is simply due to the "opposite polarity" of the hands of these prospectors.

Hours, or even days, after a person leaves a chair or bed, a good wand prospector can correctly determine a person's sex based on where the person has been.Dr. Trump calls this the "afterglow phenomenon." It doesn't matter what material the wand is made of.According to Trump, the wand only serves as a kind of muscle action indicator.If the wand prospector washes his hands from hot salt water before working, his function is "greatly improved".If the wand is grounded with a copper wire, its function is completely lost.If his forearms are exposed to direct sunlight, he will also be less functional.Wearing rubber-soled shoes will increase his sensitivity.

Dr. Trump admitted that when testing these wand prospectors, some people often get it wrong. This does not bother Trump.He lists dozens of factors that can lead to failure—fatigue, lack of concentration, poor health, apprehension, too much friction on the soles of shoes, various atmospheric conditions, interference from nearby power lines, humidity in the ground, etc. ."Trees and roots in particular seem to cause disturbances that affect accurate detection," he wrote.Even though he took all of the above reasons into account, it was clear that failures were too numerous and elusive for him to find the justification he needed for each one.None of the examples given throughout the book resemble experiments carried out under supervision.

Trump's book also spends a lot of time talking about another phenomenon similar to wand prospecting, which he believes is also due to the action of electromagnetic fields.This phenomenon is called radiosensing, and is detected by a small pendulum formed by suspending a weight on a thin chain or string.The weight is also often a ring or a small piece of metal.Like prospecting wands, other substances have also been used. "Radiosensing" may have first developed in Europe in the eighteenth century, when it was used to diagnose disease.A pendulum is suspended above the patient, and the performer does not make any conscious actions, and soon the pendulum will mysteriously swing or turn in circles.The different swing patterns are said to indicate the different ailments the patient is suffering from.Later, this method was widely used to determine the location of underground mineral deposits and buried gold and silver treasures. Dr. Trump believes that everything in the world has its special "atmosphere", that is, the electromagnetic field.A person who can feel this electromagnetic field will unconsciously translate the feeling into muscle activity, which will cause the weight to swing.Trump believes that the pendulum can be used to distinguish various metals, paintings by different artists, papers of various colors, medicines, trees and genders. According to Trump, the pendulum spins clockwise on women and counterclockwise on men.But he did not mention that many practitioners sometimes rotate the pendulum clockwise and sometimes counterclockwise when they are treating women; while they are swinging back and forth when they are treating men.The "afterglow phenomenon" is the same as above when experimenting in a place where a person has rested.Where you pissed.Or experiment on women's fetuses, and the same reaction occurs. Trump's book ends with a discussion of the nest-seeking instincts of birds and beasts and other phenomena he attributes to the effects of electromagnetic fields.He believes that the sacred wounds, telepathy, stepping on fire, touch divination, and the influence of mother's experience on the fetus of some religious mystics should all be investigated from the perspective of electromagnetic fields. He said at the end of the book: "Most scientists in the twentieth century seem to lack the courage and imagination to face problems that seem unbelievable at first glance...", "Only extraordinary scientists have the ability to quickly open this Situations." There are 1496 titles at the back of the book, 700 of which are about wand prospecting and "radiation perception". Today, there are many associations and publications in the UK and Europe that study "radiation perception", showing the popularity of this problem.In England, there is a monthly magazine titled The Magic Pendulum.In France and Germany, similar journals have been published; recently, in Italy, two new journals have appeared on the study of Radiation Perception.Charles Ford wrote: "The fact that so many scientists now believe in wand prospecting makes me wonder if it may be a myth." In 1936, German and Italian armies seriously considered using the magic pendulum as a means of finding water.In the last world war, the Germans did use this method in the North African campaign. "Radiation perception" once fascinated the successful pseudo-scientists in Hitler's army.There is ample evidence that certain sections of the German Navy actually hung the magic pendulum over a large map of the North Atlantic in order to locate enemy battleships! By the way, Dr. Trump is very disapproving of this kind of long-distance "radiation perception" and the practice of measuring with a magic pendulum or wand on the photo.This does not fit with his electromagnetic field theory. One of the favorite arguments of wand-seekers is that everything that exists for a long time must have a reason, and Trump has repeatedly repeated this argument.If someone pointed out that astrology has a longer history, they would probably say, yes, astrology may have its basis too.This is actually Trump's position as well.In one of his earlier books, The Religion of the Modern Scientist (published 1947), he argued that the planets and stars may also affect electromagnetic fields on Earth, which in turn may affect people's character and future.However, he believes that a serious mistake of astrologers is that they use the date of birth rather than the date of conception in their calculations!This error has made most past astrology meaningless, but Trump believes that this error can be corrected, and astrology can also gain an empirical basis.The photographs accompanying the book bear the title: "Capillarity of a Solution of Silver Nitrate, Iron Sulfate, and Lead Nitrate Taken Two Hours Before Saturn Conjuncts the Moon." Compared to the "scientific" veneer of Trump's Psychic Physics, Kenneth Roberts' recent book, "Henry Gross and His Prospecting Wand" (1951), reads more like a this novel.Of course, Roberts doesn't claim to be a scientist, as evidenced by his many geological jokes.For example, he embraced the theory that groundwater veins had nothing to do with the water table, but instead came from gigantic "rock domes" that arched from the depths of the earth.But in fact, the rock dome is estimated to be 57,500 feet underground!At such depths, the heat of the earth must have turned the water into steam, so that there would be no wells but fountains of hot water.The idea that water was squeezed into the dome is, of course, geologically absurd.Adding to the absurdity is Roberts's suggestion that the pressure that arches the dome is the same as "the pressure that pushes the oil up . . . "Roberts, though, did not understand the basic geological fact that oil floats on water and is squeezed upward by the water into the tight raspberry-shaped headspace. Roberts is known as a writer of popular historical fiction.He was a field editor for The Saturday Evening Post before he succeeded in writing fiction.Although he has long been interested in wand prospecting, it was not until he discovered the function of Henry Gross's wand prospecting that he devoted his main interest to this aspect.Roberts writes the story of Gross' growing power in his book, declaring that "when the potential uses of the wand become more clearly understood and harnessed, it will be as important as electricity and atomic energy." status". He asked: "Why should scientists spend time, energy, and money conducting those very problematic experiments on wand prospectors in the laboratory, instead of devoting more energy to delving into the depths of a mysterious but extremely valuable thing?" What about phenomena? This phenomenon, if properly utilized, would prevent wars, move mountains, turn deserts into fertile fields, feed the hungry, heal the sick, and change the face of the world." The man who inspired Roberts to realize this earth-shattering force was Henry Gross, game inspector for Bidford, Maine.Roberts runs a farm in nearby Kennybank. In 1947, forest fires brought severe drought to the region.Roberts asked Gross to find him a new well.He was very impressed by Gross's accuracy in choosing the well site, so he bought many books published abroad on wand prospecting and radiation perception for this friend.Gross was attracted by these books and began to experiment with his functions. In less than three years, he became an unprecedented and magical super wand prospector. Gross was able not only to point out the tortuous course of underground water veins, but also to determine the exact depth, direction and flow of the water source, and to determine whether the water was good to drink.These can all be answered by asking questions of the wand, which can answer "yes" or "no".Tilting the wand means "yes" and standing still means "no".While Gross loves freshly cut maple branches for his wand, he can use other materials, even a long blade of grass for his detection.Wearing rubber gloves, or wearing rubber-soled shoes does not affect his detection effect. In 1949, Henry Gross discovered that he didn't have to be on the spot to detect, but could also detect areas many miles away.Roberts cited many examples of Gross' success in long-distance detection, the most notable of which was his determination of the location of three freshwater sources for Bermuda in 1950.Gross probed in Kennybank, 800 miles from Bermuda! "Mrs. Roberts moves a pencil on a map of Bermuda. Gross's wand tilts every time the pencil points to the right spot. Bermuda didn't have a single freshwater well at the time and was suffering from a severe drought. Gross' prediction It was later said to be all correct. One day, Gross probed on a map of Africa and found a very large water vein under the Sahara Desert.It traverses the entire mountainous region of West Africa and flows into the Gulf of Guinea!Unfortunately, this detection was not verified. Not only can Gross find water, but he can also locate people with his wand.When he visits a friend, he doesn't need to ring the doorbell to know whether the other party is at home.The wand could tell him exactly who was in the room.He can find those who deliberately hide in the forest, and he can tell where lost things are.On one occasion, he found an outboard motor that had fallen into 16 feet of water. On another occasion, Gross and Roberts experimented with wine.Gross touched the rye whiskey once with the tip of his wand, and after that the wand only tilted towards the rye whiskey and no other alcohol.If he touched the bourbon with the tip of the wand, the wand just tilted towards the bourbon.You don't even need to rub the tip of the wand, just touch the tip of the wand to a labeled brandy bottle, and the wand can be tilted towards other brandy bottles of the same brand.Roberts wrote, "It seemed to us almost inconceivable that the smell of Scotch whiskey and brandy could emanate through glass bottles, suggesting that the smell from the magnetic north pole might pass through everything... ...". Gross read about radiation perception and began experimenting with magic pendulums.He found this thing very clever.But what is different from others is that the magic pendulum circles when hanging on a man's body, and swings back and forth when hanging on a woman's body.Roberts reported that when Gross hung the pendulum over his hand for the first time, "I felt a sting...a growing pain, as if from an electric shock, and I had to withdraw my hand...".In Gross' hands, the pendulum can pinpoint the sex of animals, birds' eggs, and even people in photographs.But there is one strange exception, if a woman's blood does not contain rhesus factor, then the magic pendulum will react male! What is the cause of all these phenomena?The examples given by a man who prayed for the help of this art, and therefore believed in it, in a similar genre of fiction, are of course not sufficient.But, leaving aside the many dubious elements of Roberts' illustrations (important omissions, unintentional exaggerations, etc.), it is not impossible to draw some conclusions. For example, there is nothing to suggest that Henry Gross is a quack, or a liar.He seems to be a simple and honest person, completely bewildered by his psychic ability and takes a keen interest in it.But on the other hand, all the circumstances show that Gross unconsciously transmitted his thoughts to the wand and pendulum through subconscious muscle movements. It is an established fact in psychology that people's thoughts can be transformed into muscle actions unconsciously.In people especially prone to this, the above facts are the cause of such "mysterious" phenomena as Ouija boards, tilting tables, automatic writing, etc.There is a kind of mind reading, often called "muscle reading" in the magic industry, which is also based on this principle.A pin is hidden in a room, and the performer can find it instantly by asking an audience member to hold his hand.The spectator thought he was being guided by the magician, but the performer had the spectator guide him through involuntary muscle contractions.There are many famous musculoskeletons who can find hidden objects without physical contact at all, just by observing the reaction of the audience in the room. Please give your undivided attention to the toes of your left foot.Do you find yourself wiggling them slightly?Or, at least trying to force myself not to twist it?There are many who cannot read without a slight movement of the lips.Involuntary muscle activity can be tested with a homemade pendulum.Hang a small ring on a two-foot wire.You say to yourself, it circles over a woman's hand, and swings back and forth over a man's hand.Then just do it.So effective for most people that for decades such pendulums were sold as "gender indicators" in novelty toy stores across the United States.The reason, of course, is that the involuntary and invisible movement of your hand is enough to make the pendulum swing the way you want it to.Prospecting wands work exactly the same way.The wand is under a lot of pressure in the hand.It is still upright, but it is not easy to maintain balance, and the slightest muscle movement can make it fall instantly.It is not surprising that a good wand prospector is almost as proficient with a magic pendulum. But, one might ask, what would happen if a wand prospector or pendulum manipulator were tested under conditions in which they did not know in advance how their tool would behave?The answer is that whenever such tests are conducted under supervised conditions, the results do not reach the level expected by the law of averages.Even in Kenneth Roberts's obviously biased book, he records a large number of facts that Henry Grossfan failed under arranged conditions that approached scientific testing.For example, if one earthen jar holds water and one earthen jar holds sand, if the two jars are hidden in two paper bags, Gross will not be able to tell the difference.Putting the envelope containing the coins on the ground with some empty envelopes, he couldn't find which one contained the coins.If he touched a coin with the tip of his wand and dropped it on the floor, his wand would point to the coin.But if someone held the coin behind their back, clenched it in one fist, and then stretched both hands out in front of them, Gross couldn't be sure which hand the coin was in. If he put the pennies in one of the medicine boxes, Gross wouldn't be able to tell which one it was in.A few gold watches and pins were buried under the turf for Gross to find, with unsatisfactory results.At one point, Gross thought his wand (he had a piece of gold on the tip) had found gold in a creek near his house.After the ore was sent for analysis, it was proved not to be gold.Explaining the failure, Roberts said: "The stream flowed first over the gold and then over the rocks, so there was enough gold left in the water to affect Gross' wand!"Since Roberts doesn't say how he came to know all this, his explanation is not at all convincing.On another occasion, Professor Joseph Laing of Duke University conducted a series of experiments in which Gross sought to determine when water was flowing in a pipe and when it was not.Gross also suffered a disastrous defeat. For this failure, Roberts made two excuses.First, he believed that the water in the pipes did not actually stop flowing after the tap was turned off.It's still in a state of "agitation".In addition, Laing experimented with Gross under artificial and unnatural conditions.Later, he wrote that he regretted not thinking of building a 20-foot-square platform, covered with soil, and run a hose underneath.The hose zigzags under the platform, then asks Gross to walk over it, indicating the curved route the hose takes.Roberts affirmed that, under such circumstances, "Gross's wand must be able to point the hose correctly... a thousand times to be sure. It's a pity I didn't think of that." What a pity!Being able to guess where the hose is a thousand times to be 100 percent accurate is the kind of experimentation that is conspicuously missing from this book.What would a competent scientist think of Roberts' assurances of the results of such an experiment that were never carried out.well!I'm afraid such an experiment will never be carried out!Gross was once challenged by a clever professor at the University of Massachusetts to perform a blindfolded experiment, but he did not dare to take up the challenge.This experiment is actually simpler.Let Gross first find out the spot where his wand is tilted most, and then, with his eyes actually blindfolded, lead him around the spot, and see if his wand is still tilted when he goes to said spot.Is there anything fairer than this? After Gross's wand failed in some of the tests mentioned above, Roberts' reaction was interesting.Did these failures remind him that he should try to arrange another experiment, such as the hose experiment he imagined, or get some scientific basis for Gross' function?No.Instead, he wrote: "If in the eyes of the scientists these experiments proved nothing, in my opinion they proved a great deal. First of all, I must try to be as minimal and skeptical as possible in any subsequent experiment of wand detection." Theorists or geologists deal with ... ". Experiments with Gross's magic pendulum feature were equally dismal.In the obstetrics department of Maine General Hospital, he once hung a magic pendulum over the abdomens of 16 pregnant women.After these pregnant women gave birth, his tests were checked.Of the 16 cases, he was correct in only 7 cases.In fact, Roberts' niece did slightly better than him in a similar experiment with 11 pregnant women.She guessed 9 cases correctly. As for Gross's success in finding water, it was pure chance.In the first place, to a person who is thoroughly familiar with the terrain, there are often many signs on the surface that provide clues to determine the source of underground water.Gross, game warden, must have known the area inside out, and was undoubtedly a smart and quick-witted man.On page 46 of the book, he detects a vein of water leading to a spot that is often "obstructed by flooding to ... agricultural machinery."Page 276 goes on to say that he selected a site for the well, where the water source was very close to the ground, and "the nearby grasslands and shrubs, even in extreme drought conditions, are still moist and green." In all respects. It turned out that he was familiar with the soil, crustal deposits, sandy beaches and other structures that characterize the area.Even though he may not be aware of it, he can easily pick out important geological clues based on his very familiar surroundings. In many cases, what Gross detected with his wand confirmed what some already knew.Think of it this way: he himself may act as an unconscious "muscle psychic man," but he gathers cues from the reactions of those present and passes this information on to him. Foremost among this factor is the simple fact that anyone who digs deep enough can come across a source of water anywhere.There are much more water sources near the surface than people imagine.In many areas, digging down at a random spot has a good chance of finding water in shallow depths.In fact, water sources rarely occur in "water veins" (except in rare cases where cracks and cavities in rocks cause this).Below a certain level, there is a variable groundwater porous structure that changes from year to year and from season to season.In many areas, it is impossible to find groundwater at all, although it is no more than a trickle enough for a family. Bermuda is one such region.As on similar limestone islands, fresh rainwater infiltrates through the porous limestone and floats on top of the salty water below.No matter where on the island, when a well is drilled to such a point, there will be an upper layer of fresh water, but only a small amount.Roberts once expressed this view to reporters: the water source Gross found in Bermuda was an underground stream from the North American continent! Even if Roberts' material is true, it records several apparent failures by Gross to detect water with his wand.Like Dr. Trump, he has a gift for talking nonsense.At one point, Gross predicted the source of the water at 16 feet, but it turned out to be at 6 feet, this time said to be because "the water vein met an obstruction . . . forming a pressure zone."On another occasion, the water veins were redirected by the use of explosives.Another time, the water source was changed due to the vibration of the drilling rig.Even the weight of a bulldozer can crush a water vein, redirecting it, Roberts contends.Since it is difficult to avoid touching the ground when drilling a well, it is not difficult to find excuses for failure.It would be nice if there was water, anywhere, as in most cases.If there is no water source, it is because the water source "changed direction".So how did Roberts know that the water vein had changed direction?That's because the water was no longer where Gross said it was, and Gross was never wrong. s.Estimates of depth are extremely difficult to identify.Roberts used to say that Gross's predictions were accurate to the nearest inch, and anyone who has ever managed to measure the depth of water in a well knows the absurdity of that level of accuracy.On several occasions, Gross' estimates were off by many feet, as is the case for many wells in Bermuda, and he estimated from Kennybank Harbor telemetry that the source was 15 feet deep.His on-site retest was 30 feet.Water was found at 73 feet when the well was finally drilled. Measuring flow is even more difficult, and it varies greatly with the seasons.As Thomas Riddick, an engineer working on the water system, wrote in "Wand Prospecting Is Nonsense" (Harper's Monthly, July 1951): "There is no water engineer in America who can Calculating the flow of any one well to the quarter gallon per minute is impossible even with the most accurate methods of measurement after a twenty-four-hour pumping test." It goes without saying that at Grosse a quart After the prediction of 1/min, few people have tested it with the same accuracy. Testing water with a wand is far from a harmless and money-saving superstition.At present, there are countless wand water testers all over the world, earning handsome rewards.More recently, Roberts and Gross set up a company called Exploring Water, Inc., which charges at least $100 per well (with travel expenses included).Some detection jobs cost as much as $1,000. Using magic pendulums and more complicated methods to find oil is even more expensive.From the earliest days of the oil industry until today, crooks and lunatics have plagued geologists and oil producers alike with a bizarre supposedly infallible method of finding oil.Originally, there was a novel method called "oil sniffing", but in recent years it has become more common to call it "prospecting magic". Usually only gullible farmers spend this kind of wronged money.A well-spoken wand prospector surveys a farm for a fee of 10 yuan or a small fortune.In the future, if an oil company drills a well on this land, it will often encounter stubborn opposition from the farmer, because he thinks the location of the well is wrong.He will insist that 10 years ago he paid a geologist "to scour the land and tell him exactly where the oil is. In many cases, people who use magical prospecting have a strong belief in this method.Often, they pride themselves on their lack of technical knowledge and strongly condemn orthodox geologists for their reluctance to accept new things.They often claim to have sent the invention to a world-renowned scientist (usually a personal friend) who admits not to understand why.Most modern magical prospecting works on the principle of gravity, or detects certain indistinct electromagnetic radiation emitted by oil deposits.These magical prospecting devices are exquisitely designed and beautifully shaped, sometimes resembling a Ruby Goldberg machine.The people who invented such devices are, without exception, the only ones who can use them correctly.If a dry well is drilled according to the results of magic prospecting, the magic prospectors will always have a ready-made reason, but there is some kind of "disturbance" that affects the detection. A petroleum geologist in Tulsa recently sent me a copy of a 1952 advertisement letter received by the city's oil operators.The content of the letter is very interesting. Here is an excerpt from it: I have studied mining and petroleum geology for many years... and have a broad and general knowledge. ...I have spent more than 100,000 US dollars and many years to study a special method of magnetic logging....This method can achieve more than 90 percent accuracy. ...I have decided to selectively provide commercial Excellent service and rich experience... In view of the fact that operators can obtain millions of income by using these services and experience, we will charge reasonable service fees... ... My time is very limited, so please take care of me... He charges $1,000 for a general report on an area. Of course, the chance of finding oil in a blindly dug well is much less than that of finding water in a blindly dug water well.But, as one might expect, there have been successes, none more so than the 1943 discovery of the West Edmond oil field in central Oklahoma. The well was dug by a blind driller named Ice Gutowski, and financed by the Fox Bruin Company of Chicago.How did Ace determine the location of the well?There was a farmer living there named J. W．Jan, he has a bottle covered in goat skin that contains a mysterious substance, which he refuses to reveal.The bottle is hung on a watch chain. Where there is oil underground, the bottle swings north and south, and where there is salt water underground, the bottle swings east and west. 我有一位朋友，是地球物理学家。1944年他曾在埃德蒙的一家饭馆里见识过扬的这个宝物。瓶子吊在作试验用的沙子上面。瓶子工作得很好，但是我的朋友发现扬患有麻痹症，以致他抬手时发生明显的颤抖。 不管怎么说，古托夫斯基打的这口并揭开了20年来在俄克拉何马州发现的最大油层！而且，这个油层的结构，是属于用正统的地质学和地球物理学方法无法探测出来的一种类型。 这个故事还有更精采之处。无限笃信自己魔法的农民扬在这个地方购置了土地。新油田逐步扩大，最后到达了扬的地产边界。但是就此为止。因为在扬的土地上打了该油田有史以来第一口干井！
