A Sober Appraisal of "the Flying Saucer" (1948)

JF Ptak Science Books  Quick Post

This slightly engaging cover of Popular Science offers its readers a sober appraisal of the still very popularly new phenomenon of “the flying saucer”. Not “flying saucer” plural--”the” flying saucer phenom, complete at this point with a definite article...I have no idea when the “the” disappeared. In any event it is a pretty good explanation, though there is no mention here of “The Battle of Los Angeles”, when in 1942 aircraft batteries and searchlights blazed away into the high night air trying to stop a supposed Japanese attack. Six people on the ground were killed by shrapnel and debris, with no damage to anything flying overhead reported. There were some wild theories about what the “attack” was, along with accusations of cover-ups and political/economic conspiracies, and that seems to have been the extent of the matter. In any event, Pop Sci takes up the case of the weather balloon as a general explanation to people seeing intelligent life forms scooting around in our sky but not bothering to stop and say “hello”.

Just in case anyone is interested, here's the Oxford English Dictionary entry for “flying saucer”:

--flying saucer  n. the fanciful name given to various unidentified disc- or saucer-shaped objects reported as appearing in the sky.

• 1947   Times 8 July 4/4   During the past fortnight reports that dish-like objects, nicknamed ‘flying saucers’, have been seen travelling through the air at great speed..have come from the United States and Canada.
• 1948   Jrnl. Brit. Interplanetary Soc. 7 199   I haven't examined the details carefully, but the ‘flying saucers’ bear all the hall-marks of mass-suggestion.
• 1953   D. Leslie & G. Adamski Flying Saucers have Landed i. i. 13   Ever since the cliché ‘flying saucer’ was coined, the greatest and most exciting mystery of our age has been automatically reduced to the level of a music hall joke.
• 1965   New Society 9 Sept. 14/2   When Kenneth Arnold saw something from his airplane near Mount Rainier in June 1947, he gave them the happy name of flying saucers.

Nature Magazine Reviews Hitler (1933)

JF Ptak Science Books  Quick Post

Here's a razor-sharp summation and review of Adolf Hitler, being an uncommon appearance of that man and his "science" in Nature, volume 132, p. 198, 1933. 

"That the Nazi leader stands self-revealed as an ill-balanced, fanatical and otherwise abnormal is immaterial. What is supremely significant is that he has come into power on a wave of popular discontent  with present day social, political and economic conditions which is sufficiently intense to submit to previously unheard of restrictions for which a "scientific" backing is advanced."

A Nasty Piece of Propaganda from French Collaborationists (1943)

JF Ptak Science Books   Quick Post

The offending pamphlet here is a celebration of the invasion of the Soviet Union by Germany, a "two year anniversary" of the beginning of "Operation Barbarossa". The author(s) presented the new front in WWII as a "joined" effort on the part of European nations to rid the world of the Bolshevik threat. (The title of the work: Toute l'Europe contre le Bolchevisme, 2^eme Anniversaire which was published by CEA, the Centre d’Etude Antibolchéviquethe (Anti-Bolshevik Studies organization), a French organization running with Nazi funding.)

The pamphlet of course fails to mention the turning of the tide against the Germans, especially with the defeat and destruction of von Paulus and the 6th Army at Stalingrad in January/February 1943, the failure of the Caucasus push, and so on. Then again, this is a piece of propaganda, and facts can be conveniently excluded whenever necessary.  A few pages later by the way there is the introduction of Bolshevism being the invention of "International Judaism" and other anti-Semitic lies that was an attempt to perpetuate the fiction of the Nazis and the Allies working together to defeat Stalin and his Jewish co-conspirators in quest of world domination.. Besides the text supporting this stab-in-the-heart thinking is a horrible caricature of "international Jewry" combining with Bolshevism and Freemasonry (?) as a force out to capture the world. 

Events antithetical to this propaganda were excluded--I did check out some of the numbers for the battle represented below (like Smolensk and Vizma (Moscow) and those are correct...these battles were mainly fought in 1941/early 1942 at which point the Nazi offensive was still going forward, so there's not much from 1943. So numbers and events that supported the crucially insane claims of the pamphlet were used; everything else was ignored or re-packaged with false data and employed. 

When the Opposite of an Idea is the Better Idea (1922)

JF Ptak Science Books  Quick Post

Here's a suggestion for a new category for this blog: Ideas That May Be Better Backwards. The idea is presented in this wonderful image from Popular Mechanics in 1922 and features an endless trolley/conveyor of food that moves past stationary diners at a restaurant. You'd sit down, and gobs of food would be presented on an endless conveyor, moving along at probably 1 mph. This idea makes sort of very quick 3-beer sense, until you think of the probable waste and the cost of machinery and energy that it took to trundle the food along, and then replacing all of it that went cold, and so on. It seems to me the opposite might be the better if not still-bad idea: putting the patron seating area on a revolving stage and have a central location for the food where they'd take what they wanted. The conveyor-of-food idea withers next to the great Automat, where people would simply walk up to a long bank of small windowed receptacles with different foods inside, drop a few coins into the slot opening the lovely little (but thick) door, after which you'd simply find a place to sit and eat. (This automat was a German 19th c idea, and it became popular in the U.S. in the 1930s'-1960's, with Horn & Hardart leading the way with 30 or so locations in NYC. The H&H variety closed up by the early 1990's, their locations converted into Burger King meat/fat/carb slingshops.) Here it is:

 The image reminded me of one I saw for the very restrictive penitent/observer prisoner in chapel at Pentonville Prison in 1855--I know it is hardly similar whatsoever to the food-on-a-belt, but the two did come together somehow in my head:

A Tank at an Amusement Park (1920)

JF Ptak Science Books  Quick Post

There is something lingering and heartbreaking about this image found in Popular Mechanics for July, 1920. The image shows a refitted tank being used as a curious ride at an amusement park. No doubt people wanted to put WWI behind them, as the end of the war was still only two years old or so, and the imagery of millions of people killed during the conflict was still very recent, with the hardships and loss still quite present in the minds of nearly everyone in the world.  That said, the image of the smiling faces on the retrofitted tanks a bit much, seeming to be this side of disrespectful. Seeing the "Jeep" brand doesn't affect me like this--as the logo has almost nothing left in connection to the WWII vehicle, though I do feel a bit annoyed when I see a deluxe High Mobility Multipurpose Wheeled Vehicle  HMMWV, or Humvee) tooling around in the suburbs, begging attention in its mostly-useless incarnation, carrying with them the memory of hundreds of U.S. soldiers being killed in them. I just don't like the idea of desensitizing the imagery of these vehicles into something sugary. 

When the Words Feel Like the Bad Paper They're Written On--Trashing Frederick Douglass (1895)

JF Ptak Science Books  

1895 was a great big year in science--there were major contributions by Cantor, Poincare, Ramsay, and Perrin, among others, though the biggest of them all was the semi-accidental discovery by Roentgen of X-rays, a monument in the pursuit of further/deeper.

My own little 1895 discovery last night may be a well-established bit but was unknown to me, and it proved to be the opposite of further/deeper. I was trying to squeeze some life out of what looked like a pamphlet as dry and brittle as the bad newsprint it was made of:  History of the General Assembly of North Carolina, January 9-March 15, 1895, Inclusive (printed by E.M. Uzzell in Raleigh, 1895), which sounds just flat-out anti-interesting (especially with the very specialized time period).  It turns out that the 160-page work is written in a easy, journalismo sub-Menckian way, with a nod to humor here and there and a dose of familiarity, a good narrative style that was useful and breezy.

And as I hunted for some sparkly point in the daily comings and goings of the legislature, I ran right into the dark void.

The hole was a short report, “The Douglass Infamy”, which was an infamy of its own. Over the few pages of the article/review it discussed the  “humiliation of the white people of the south” caused by the General Assembly of the legislature choosing to suspend and adjourn their meeting out of respect  for Frederick Douglass, who had suddenly died during the session. The author referred to the action as "an offense against the dignity and sentiments of this proud State" ("State" is capitalized, "Negro" is not),  Douglass to as “the miscegentionist" straight-away after condemning the act of respect due the man, and was an "...author of many malignant and untruthful aspersions on the whites",  and referred to his as "an inferior race, incapable of civilization except for that under the whites".  Closing down the government was a "humiliation to white people" and disgusted some legislators to the point where they denied that the action had taken place. I think this was because it elevated Douglass to a level of equality, which just would not do: "The whites of North Carolina...regard any approach by the Negro to social equality with...abhorence [sic]". 

The was a significant amount of hateful nonsense in this entry, railing against Douglass, who in their view wrote terrible untruths about white people and who was “also guilty of miscegenation”, having married a white woman.  

“Thoughtful Democrats who have looked beyond the present moment and who have preferred to bear such party ills as they had, if such there were, rather than fly to others they knew not of, predicted that the fusion with Republicans of any considerable number of those who were formerly Democrats meant Republican domination, and that Republican domination meant, in one form or another, negro [sic] domination. The Douglas incident reveals the animus of that party and is a menace of its aims. (After the official declaration of the Fusionists, the General Assembly did not adjourn in honor of the birthday of Robert E. Lee, a legal holiday, but did adjourn out of respect for the memory of Frederick Douglas.)”

Finding this article was not surprising, really, though it was unexpected to some degree; there were a few other bits in the pamphlet similar to this, so the article did not stand alone. The part that is so amazing is that it the "Douglass Infamy" was just part and parcel of a documentary and interpretive  report on the action of the state legislature for a few months in 1895; and yet, there was this hateful business, taking up as much space and brain waves as noting that it was a cloudy day.  

Massive Paper Coronary for the Coroner’s Office of NYC, 1915

JF Ptak Science Books   Quick Post

If you ever had any interest—known and unknown—in reading about very impressive amounts of corruption and its constituents in the coroner’s office for NYC 104 years ago, here’s your chance to satisfy it. I’ve found a scarce report documenting the extraordinary conditions of that agency and also found a copy of it online, and include a link to the report (below).

You don’t want to be on the other end of this paper—it is scathing, and angry, and well-written and documented. From a quick read of it the office of the coroner of NYC was simply a fantastic mess of incompetent work and very highly competent corruption.

The report starts at the end, with a summary of findings, and then goes downhill from there:

• “The elective coroner in New York City represents a combination of power, obscurity and irresponsibility which has resulted in inefficiency and malfeasance in the administration of the office. With constant temptation and easy opportunity for favoritism and even extortion, with utter lack of supervision and control, and without the slightest preparation and training to create in the coroner's mind a scientific and professional interest in the performance of his duties, the present system could not have been better devised intentionally to render improbable, if not impossible, the honest and efficient performance of the important public function entrusted to his office.

Of the 65 men who have held the office of coroner since consolidation, not one was thoroughly qualified by training or experience for the adequate performance of his duties….”

There’s a ton of bitter accusation of wrongdoing along with the evidence to back it up.

A Not-So-Good Idea for Air Travel (1922)

JF Ptak Science Books   Quick Post

This October issue of Popular Mechanics 1922 is robust! Here's another attractive piece of design with loads of character and one central question:  "why?"  The image is that of a giant aeroplane capable of hauling 100 or more souls (not this particular version, though) for long distance uninterrupted flight of 1000 miles--so in order for there to be no in-between landings the aircraft came equipped with a glider aircraft (an altogether different version of the "hang glider") that was released for the mother ship. As you can see it is a much smaller aircraft and looks to me to be pretty well packed, leading no doubt to questionable utility and much prayer. The thing is, why bother with another aircraft when you can just stop the plane and let people off? This beast was half-stopped in the air anyway by modern standards, probably chugging away at, what, 100mph? (The airspeed record at this time was just a touch over 200mph.) and it wasn't flying very high (relative to even 1950), so stopping may not have been such a big deal. The airport or air station wouldn't've been an issue either, because the glider would near to land somewhere. Anyway, I just couldn't figure out this piece of The Possible Future.

A Different Sort of Motorcycle Sidecar (1917)

JF Ptak Science Books   Quick Post
This unlikely combination of vehicle and fuel source appeared in Popular Mechanics for June, 1917. 

It was fueled by "illuminating gas" which was a hydrogen/hydrocarbon mix and which was made to fire street lamps and such, a destructive process introduced in the very early 19th c.  It is highly flammable. Highly.

This suggestion for a 600 cubic ft power envelope for a motorcycle was supposed to save about two-thirds on fuel costs and replace the use of wartime gasoline, but...

Infiltrating Fascist Sympathizer Groups in the U.S. (1943)

JF Ptak Science Books  Quick Post

John Roy Carlson (the pseudonym of Arthur Derounien, 1909-1991) was an investigative journalist and during WWII he went undercover and infiltrated many of the right wing/fascist/"patriot" groups operating in the U.S.  The result of that work as a  well-received book called Undercover, My Four Years in the Nazi Underworld of America¹, which was published by Dutton in 1943 and which went through seven printings in its first two months of publication.  It wasn't yellow journalism, either--it was an expose of Nazi and fascist sympathizers, who--even after Pearl Harbor--supported the ideas of fascism.

Derounien was a busy man, joining and infiltrating such groups as:

• National Socialist White People's Party (formed by George Lincoln Rockwell in a shabby store front on Wilson Blvd in Arlington,Virginia, and renamed the American Nazi Party in 1960);
• Christian Mobilizers (allied with the Bund, this was a militant arm of the Christian Front which had a more-militant spin-off in the American Unity Party);
• America First Committee (a mixture of patriotic, isolationist far right-wing and Nazi sympathizers, infamously spearheaded by Lindbergh, the group disappeared on 7 December 1941; 
• German American Bund, (a loud German-patriotic pro-Nazi group which filled Madison Square Garden in 1939 with 20,000 members, sweatily drenched in Hitler rhetoric, an enormous portrait of G. Washington, Brownshirts,  and swastikas: https://www.theatlantic.com/video/index/542499/marshall-curry-nazi-rally-madison-square-garden-1939/);

plus the Gray Shirts (not to be confused with local boy Pelley's Silver Shirts, abandoned after his jail sentence for sedition and replaced in the 1950's with his new religion of UFOs and religious-something called "Soulcraft"), American Nationalist Party, American Women Against Communism, The American Defense Society, Anglo-Saxon Federation of America, National Workers League, Yankee Freemen, Flanders Hall, American Patriots, and others²--it was a very impressive undertaking. 

[German American Bund at Madison Square Garden, 20 February 1939.  Source: https://youtu.be/WpaYQqzFouw]

His book had a very wide impact, contributing to some degree in bringing together thirty leaders of such groups to trials for sedition during wartime. Carlson had in the intervening year or so, 1943/4, been subject to many accusations and charges of being an enemy alien himself, or Communist, or something--accusations initiated by many of the groups that he exposed. So it seems that in preparing himself for the trials to come that in anticipation of more libels to come Carlson published this short broadsheet call Under Cover News, which appeared five days before D-Day, June 1, 1944.  In it he asked himself questions that he thought his detractors might ask, and answered them.

A Bridge for Carrying a Ferry Over Water (1869)

JF Ptak Science Books  Post 2755   

I don't mean to appropriate the past from my seat here in the future, raising my eyebrows over what definitely seems to be an Ig Nobel engineering effort, but, well, there are times when you distill a bad idea over a low flame that the bad idea distilled is still a bad idea. 

I've tried to imagine the circumstance in which this bridge would make sense, particularly in light of the fact that it was a proposal by J.W. Morse to counter the Roebling plan to erect the East River (later “Brooklyn”) Bridge in about the same location. This is how this bridge plays itself out in my mind: a suspension bridge of some substantial size is constructed to carry a ferry from Manhattan to Brooklyn, even though it seems that a ferry would be able to get from one place to the other with not terrible fuss, except in the old style of using a boat it would be moving on/in the river rather than over it. The ferry wouldn't need a bridge to cross the river if it didn't wholly depend on one from completing its task, which ferries almost never do, being watercraft and all.

The details of the plan are a little shocking: that “car” hanging from the bridge cables measured 160'x40' (6400 square feet) and two storeys high, and was meant to carry 5,000 people at one time (75,000 over a 12-hour period) along with another 500 horses and carts on the lower level. It was to make the trip in a minute or two, and would be moved from one point to the other at a few feet above the river.

This might make sense if the river was choppy, or ice-bound, at which point it would be nice to use HyrdoplanePunk to get across the river. A bridge-as-bridge would accomplish this task without turning itself basically upside down and inside-out. 

As I said it is not so good to judge application of technology by a modern standard; though in this case it seems as though if you were to look just slightly into the future from 1869 that you'd realize a continuous flow across the river would be highly preferable to a car shuttling a limited number back and forth. In addition to numerous other issues, I'm not sure how the engineer was dealing with the traffic and congestion caused by the fits and starts of 1,000 or 2,500 (let alone 5,000) people plus freight leaving the car/boat all at once, joining a crowd of people and horses and so on waiting to board, dozens of times a day.

At the end of it all, this bridge is also just not very attractive, and not made for the ages—it seems temporary, a short range solution to a long range issue, something soon to be dismantled, used elsewhere, and then scrapped.

I should point out that there is a variety of bridge dedicated to this sort of transportation—it is evidently of French origin, and referred to as a pont a transbordeur, and seems to have some utility here and there, though that “here” and “there” did not include “Manhattan” and “Brooklyn”.

• From the article:  "While plans have now been divulged to connect the island of Manhattan in New York with Brooklyn by means of a giant suspension bridge over the East River, Mr. J. W. Morse has devised a bridge which permits of a much lighter construction than a normal suspension bridge and is, consequently, much cheaper to build. Mr Morse's project provides for transportation across the river in a giant platform, suspended by means of cables from a trolley running upon a gantry across the river. Measuring 40 X 160 feet, the platform has two stories: the top floor is for pedestrians while the bottom deck is intended for horses and carriages. While a normal suspension bridge requires extensive abutments and ramps to enable the road traffic to reach the bridge-deck level of almost 120 feet, Mr. Morse's transporter bridge obviates the need for such provisions. The fact that the traveller [sic] hangs only 3 feet above the water-and hence is almost at street-level-makes it easy for heavily loaded wagons to cross the river, and will also be appreciated by the workman returning home on foot after a hard day's toil in the factory or warehouse." --Scientific American,  24 May, 1869

The Mystery of Suggested Promise--an Advertisement for Electrical Cure of Diseases (1885)

JF Ptak Science Books

I'm stepping right into the middle of this one--there's a ton of material before and after this ad appeared in 1885 on the invention of the idea of curative factors of applying electricity in medical pursuits. It goes on to day of course but now the electrical stimulation will actually help rather than just simply electrically remove the money from your wallet. This ad happened to catch my eye while looking for telephone ads in the 1885 volume (#4) of Electrical World, mainly because of the graphics of the inventor, Dr. Kidder, happily satisfied and nonchalantly controlling a lightning bolt ignite the charge of a mortar--why a mortar, I don't know. (There's a slim chance for mortar-and-pestle, the mortar here being a siege weapon and the pestle being lightning issuing some sort of electrical wonder "pharmaceutical", but I think that's overthinking the image.) In any event the electric charge to the mortar spears various diseases and complains (including neuralgia, gout, paralysis, debility, dyspepsia, and headache) with electrical bolts/something, offering a cure to the afflicted with lightning speed. 

I'm not sure of Jerome Kidder's background as there are at least two I've found online that could be him, so I'll just continue on personal history in ignorance. Seems to me though that he must've known that whatever it was he was peddling just didn't work. 

A Small Episode in the History of Irony: On-Beyond Common Sense Rules from the Successor Company Which Built the World's Most Fatality-Stricken Railroad

JF Ptak Science Books   Quick Post

The Panama Railroad was flat-out more costly in the terms of human lives than any railroad ever built in the Americas.  Probably anywhere in the world, at any time, mile-for-mile. From 1851 until it was finished in 1855 the railroad linking the oceans was a thin ribbon of red that was 47 miles long and cost perhaps 12,000 lives. The Panama Railroad Company admitted to something like 1500 deaths or some such, I forget now--it was impossibly low, particularly since the only thing they seemed to do with the bodies of non-white laborers was bury them or sell them to medical schools far and wide...they most certainly did not count them. There is no record of perhaps 10,000 dead laborers, and there never will be.  

The railroad was being built in an impossibly bad place, with no utilizable natural resources, no laboring population to hire, and so on, all the while taking place in fantastically bad circumstances. As much as landslides and accidents took the lives of workers, they also succumbed to smallpox, dysentery, cholera, various types of fevers, and a host of other killers. Melancholia and depression also took the lives of perhaps 1000 Chinese workers, who it seems took their own lives for terrible living conditions, terrible pay, and terrible human treatment. It seems too astonishing to be so, but I've read a number of accounts of the so-called "Chinese Tragedy", and it bears up. 

And so all of this bubbled up when I found this very small and incredibly skinny hardback publication from the Panama Railroad Company called Safety Rules. It seemed terribly ironic. 

Now this was not the same company though it carried the same company name as the originator, this rule book being published in the "C.Z." ("Canal Zone") in 1945, and 80-some years separated the two, but I couldn't shake the terrible connection of opposites, especially given the breadth of the 255 rules in the rule book, many of which were incredibly obvious. I've included the first few rules in the book, #1 being not to hop off a moving train in front of it...that's even a hard sentence fragment to write, let alone conjure why it was written in the first place.

"Should Britain Fight?" An argument for Appeasement, 1938

JF Ptak Science Books  Post 2753

There were some in Great Britain who just simply did not want to become involved in the European crisis, and who saw their way around the obvious to the in-obvious of what needed to be seen. That, or the source of info leading to this opinion was limited. Or, the information sources were good but the interpretation was limited. Or it was too early in the process of war...except in this case, in the pamphlet below, it was already 1938, and the issue was Hitler and Czechoslovakia.

It is a little difficult to say when this was published in 1938--if it was published in the early Spring the Anschluss would not yet have occurred, and so no mention; but I have a feeling that this is post-Anschluss, and the event (of March 1938) is treated with silence, as it surely would not have fit very well with the writer's denouncing of the diatribes against Hitler. My suspicion is that this was post-Anschluss and pre-Munch Agreement/Diktat (30 September), and that the entire business with Austria is left out of whatever thinking is going on here. There is a mention of strengthening Chamberlain's hand though nothing specifically about the Munich meeting, so my general reaction is that this pamphlet was printed in the Summer of 1938. 

The case that the author makes is that the Sudeten Germans “are suffering from intolerable grievances” and that anything to the contrary is a construction of “the Press” who were implying that the troubles were “mostly imaginary”, “therefore assuming that Hitler is trumping up an agitation as a mere excuse for aggression which would endanger the peace of Europe”, and so on. Any sort of European war coming as a result of  an involvement over Czechoslovakia, the author contends, would result in "world Bolshevism", no matter the winning side. Thus the need for Great Britain to stay away from any possible conflict, and that its only "moral position" would be to see justice done to the Sudenten Germans.  Poland and Hungary would carve up their own slices of the rest of Czechoslovakia in October and November 1938, and then come March 1939 Germany would seep into what was left of the country, completing the death of the six-month Munich agreements. 

And somehow the ending argument was that even if Central and Southern Europe were “dominated” by Germany, “she will be a disunited, and therefore weaker country, Balkanized out of any resemblance to her present self”.

In any event, these sentiments were hardly unknown, in any country. The U.S. certainly had its fair share of groups espousing these beliefs, some --like the "America First" organization--held on to their keep-our-distance programs 28 months into the war, only disappearing on December 7, 1941.

Using a Stick to Find Fugitive Murderers (1693)

JF Ptak Science Books Quick Post

Here's a quick bit, found in the title of a book that I bumped into--one could evidently hire a dowser to find "fugitive murderers" and "robbers" in addition to precious ore, and water, and treasures, and what-have-you. It appears in Pierre Le Lorrain,  l'Abbe de Vallemont's  La Physique occulte, ou Traité de la baguette divinatoire et de son utilité pour la découverte des sources d'eau, des minières, des trésors cachez, des voleurs et des meurtriers fugitifs. Avec des principes qui expliquent les phénomènes les plus obscurs de la Nature (1693) which almost translates by itself to "Occult Physics, or the Treatise of the Divine Wand and its Use in Discovering Water Springs, Mining, Hidden Treasures, Robbers and Fugitive Murders. With principles that explain the darkest phenomena of Nature". 

The subject of dowsing is just something I cannot spend any time on, except to say that it was of particular interest at this time (in the late 17th century), and that in addition to this semi-spiritual mind-application of mining and etc. M. Le Lorrain (1649-1721) also includes astrological tables to help in the pursuit of the inexplicable. I don't know how that was supposed to work outside of making his hocus pocus less approachable and more complex by showering it in complicated-looking astrological diagrams, showing that "science" was at work.

In addition to all of the other gifts that Le Lorrain's practice offered, finding robbers and "fugitive murderers" were among its talent set. And why not? Perhaps the practice was entirely removed and existed in a set of unexpected Umwelten. Perhaps the diving involved "need" as a confluence of the alignment of the stars and the specific needs of finding water, or criminals, each of which would offer its own vapor-need trails to the diviner.  (As it turns out it seems that need/vapor-need wasn't too far off a guess, as Le Lorrain thought the connection to be invisible corpuscles.) In any event, that world is a secret one, with the answers to exactly what it is all about (present tense intended) probably answerable on a Ouija board, even though in other aspects of his life Le Lorrain was a man with a scientific background (writing on the Copernican cosmology and on magnets).  As I've already said a couple of times, I don't understand this. 

• An epigram on dowsing/diving, the rod being known in Latin as Virgula Divina. The rod makes an appearance here, in 1651, a hundred years after it makes its first appearance in general, in print. Water-finding by divination etc. is an ancient practice, though the special stick that is now associated with it seems not to be mentioned until much later.

Virgula divina.

"Some Sorcerers do boast they have a Rod,

Gather'd with Vowes and Sacrifice,

And (borne about) will strangely nod

To hidden Treasure where it lies;

Mankind is (sure) that Rod divine,

For to the Wealthiest (ever) they incline."--Samuel Sheppard, from Epigrams theological, philosophical, and romantick (1651)
