As a comparison take for example WE Sanders. What do we know about him? Well we know he was an adult male who played cards. My guess for the number of adult male who played cards in the US is about 5 million. What else do we know about him that allows us to narrow it down statistically? We don't even know he was in Chicago at the right time let alone had any business with McKinney. He doesn't sound anything like Erdnase, which is a big point against him.
There are many strong connections with Sanders. First off, Sanders not only played cards but wrote down a magic trick! And he brought several boxes of playing cards with him on a packing list for a trip. Not to mention the Erdnase/earth-nose/mining connection, the history of playing around with anagrams, interest in dialectical speech patterns, and several other strong links.
And I *totally* disagree that Sanders sounds nothing like Erdnase. Unlike Galloway his writing style and word choice is very similar to Erdnase. To me this is one of the strongest of the many pieces of evidence for Sanders. Here's a sampling (i posted many of these sometime ago in this same thread):
Erdnase: he coolly proposes to "MAKE GOOD" by transforming the wrong card
Sanders: Has "MADE GOOD" at the bar, where he shines
Erdnase: It is almost AN AXIOM that a novice will win his first stake.
Sanders: this latter is AN AXIOM in mining during this period of development, and should be invariably followed where possible.
Erdnase: it may enable the skilled in deception to take A POST-GRADUATE COURSE in the highest and most artistic branches of his vocation
Sanders: during the following year he took A POST-GRADUATE COURSE in Civil Engineering
Erdnase: the average card player
Sanders: the average mining engineer
Erdnase: The first described is AN EXCELLENT ONE for retaining either the top or bottom stock...
Erdnase: The position is AN EXCELLENT ONE for ordinary dealing, and should never be changed.
Sanders: this joint is without doubt AN EXCELLENT ONE when, and only when, ....
Erdnase: DESCRIBING with detail and illustration EVERY KNOWN expedient, manoeuvre and strategm of the expert card handler
Sanders: the mines operated under these methods PRESENT EVERY KNOWN characteristic of lode formation.
Erdnase: LITTLE OR NO skill is required, BUT a practiced hand can locate and bring the cards to the top
Sanders: large excavations may be supported with LITTLE OR NO timbering, BUT usually...
Erdnase: various METHODS OF LOCATING AND PRODUCING selected cards
Sanders: the METHODS OF LOCATING AND ALIGNING the sets are those used for...
Erdase: An expert can run the whole deck WITH THE UTMOST rapidity
Sanders: huge timbers that have been framed WITH THE UTMOST precision
Erdnase: though this method IS now BY FAR THE MORE prevalent among men who play for money
Sanders: this station, while requiring more excavating to construct, IS BY FAR THE MOST economical in the end
Erdnase: we shall describe several of the BEST METHODS known for secretly exchanging
Erdnase: the BEST AND SIMPLEST METHODS of accomplishing the sleights
Sanders: probably the SIMPLEST METHOD OF aligning the side plates of inclined-shaft sets
Sanders: being the SIMPLEST AND CHEAPEST METHOD OF framing
Erdnase: if requested to determine from what single artifice THE GREATEST ADVANTAGE is derived we would unhesitatingly decide...
Sanders: the plan above described may be of THE GREATEST ADVANTAGE in blocking-out the ores for purposes of description and localization; and it may be employed with great benefit in connection with...
** Both OFFER a TREATISE and stress the IMPORTANCE of DETAILS **
Erdnase: A TREATISE on the Science and Art of Manipulating Cards
Erdnase: the sum of our present knowledge is PROFFERED THIS IN VOLUME
Erdnase: IMPORTANCE of DETAILS [full section heading]
Sanders: it has appeared worth while to make the present COLLECTION WHICH IS OFFERED not as a complete TREATISE on the subject, but rather as a series of essays which go fully into many IMPORTANT DETAILS
** Both justify the use of CERTAIN TERMS AND SYMBOLS for THE SAKE OF BREVITY **
Erdnase: Many of the methods of card manipulation explained in this work originated with us, and we have, in describing the various processes and conditions, used CERTAIN TERMS for the SAKE OF BREVITY, to DESIGNATE the particular matters referred to.
Sanders: for the SAKE OF BREVITY in description, CERTAIN SYMBOLS letters or figures, are employed to DESIGNATE the various mine workings, as follows:
Sanders: they are thus marked, CERTAIN SYMBOLS may be discarded for the SAKE OF BREVITY, and only such as are essential to the DESCRIPTION of the working be employed.
** Both take time to describe the relevance of the illustrations **
Erdnase: Therefore the writer has expended much time and care in illustrating many manoeuvres that at first may seem unimportant, but all of which are essential to the curriculum of artistic card handling.
Sanders: in the figures drawn to illustrate the article, sizes of timber most frequently used have been arbitrarily taken for convenience. The figures giving dimensions are working drawings showing the methods of framing, as explained, and can easily be applied to frames and timbers of any desired dimensions.
** Both give disclaimers, describing the author's intentions and the limitations of what is covered **
Erdnase: IT IS NOT OUR PURPOSE TO DESCRIBE the various kinds of apparatus, or prepared or mechanical cards, that play so great a part in the professional conjurer's startling exhibitions.
Sanders: IT IS NOT THE PROVINCE OF THIS ARTICLE TO TOUCH UPON methods of mining in use above ground, whether by hydraulic mining, or other processes, but rather to deal with the support of underground excavations by the use of timbers, and the details of mining therewith connected. NOR IS IT INTENDED TO ...
