Even though your guess is incorrect, I have to give you an A for effort, Steve. Tarbell didn't actually begin corresponding with Barton until 1919 when Barton sent her a letter (to which Tarbell didn't respond until 1923, and we get mad if a text isn't replied to within an hour!). And while they were civil to one another in their correspondence, there was a deep rivalry between them otherwise.
Great example of logical thinking, though!

Abraham Lincoln is the only man, dead or alive, with whom I could have spent five years without one hour of boredom.
