Re: alleged Lincoln quote:
"I see in the near future a crisis approaching that unnerves me and causes me to tremble for the safety of my country.
As a result of the war, corporations have been enthroned and an era of corruption in high places will follow..."
Further research turned up:

- According to Wikiquotes here your alleged Lincoln quote is first found at the Journal of United Labor (Vol 8, no. 20, Nov. 19, 1887, pg. 2).
The Journal of United Labor was published in Marblehead, near Boston, MA, and was house organ for the Noble and Holy Order of the Knights of Labor, an early radical labor union. The JUL link above is to the Library of Congress, which I've never used and wouldn't know how.
- Here wikiquotes discusses disputes about this alleged quote.
- Here we see where wikiquotes calls the Lincoln quote "misattributed" rather than "disputed" and cites the Journal of United Labor as its first appearance.
They also quote Lincoln's secretary, John Nicolay, as saying, in full: "This alleged quotation from Mr. Lincoln is a bald, unblushing forgery.
The great President never said it or wrote it, and never said or wrote anything that by the utmost license could be distorted to resemble it."
The source for Nicolay's quote is a New York Times article titled: "A popocratic forgery" dated October 3, 1896, which is available online, but behind their subscription paywall = $1 per month.
Btw, "popocratic" is a clever portmanteau combining "populist" with "Democratic" = "popocratic".
That is the source of the alleged Lincoln quote, according to the NYTimes in 1896. - There is a second early source listed by wikiquotes: the 20 May 1898 periodical "The Flaming Sword" here
So I found and read through the entire May 20 edition of Flaming Sword, twice, but did not see this particular Lincoln quote mentioned at all.
There was, seemingly, a different Lincoln quote referred to, but not this one.
Bottom line: the copy in wikiquotes of the article in
Journal of United Labor, citing this alleged Lincoln quote, seems to me detailed enough to be genuine, which means we can now put the alleged Lincoln quote's earliest confirmed appearance as November 19, 1887, in the house organ of the Knights of Labor.
And this, we can easily assume, is the source for Jack London's use of the quote in his 1908 book, "The Iron Heel".
I have been waiting for you to respond to message #74 because it contains more of the quote, and also another quote by Lincoln which is similar, (So much for what John Nicolay says about it) and the link I gave you goes to a webpage where the guy claims to have found the actual source of the quote.
For some reason you have ignored message #74, and at first I thought it was because you didn't like the ramifications of it and didn't want to address it.
Did you just overlook it?
