After the speech was recited it attracted much attention; was published in newspapers, periodicals, etc., and was extensively quoted. Jefferson, as we learn from his Papers at Washington, took it down in 1775, getting it from Lord Dunmore's officers, and published it in his "Notes," in 1784; unfortunately he took for granted that its allegations as regards Cresap were true, and accordingly prefaced it by a very unjust attack on the reputed murderer. Until thirteen years after this publication, and until twenty-three years after the speech had been published for the first time, no one thought of questioning it. Then Luther Martin, of Maryland, attacked its authenticity, partly because he was Cresap's son-in-law, and partly because he was a Federalist and a bitter opponent of Jefferson. Like all of his successors in the same line, he confused two entirely distinct things, viz., the justice of the charge against Cresap, and the authenticity of Logan's speech. His controversy with Jefferson grew very bitter. He succeeded in showing clearly that Cresap was wrongly accused by Logan; he utterly failed to impugn the authenticity of the latter's speech. Jefferson, thanks to a letter he received from Clark, must have known that Cresap had been accused wrongly; but he was irritated by the controversy, and characteristically refrained in any of his publications from doing justice to the slandered man's memory. A Mr. Jacobs soon afterwards wrote a life of Cresap, in which he attempted both of the feats aimed at by Martin; it is quite an interesting production, but exceedingly weak in its arguments. Neville B. Craig, in the February, 1847, number of _The Olden Time_, a historical magazine, followed on the same lines. Finally, Brantz Mayer, in his very interesting little book, "Logan and Cresap," went over the whole matter in a much fairer manner than his predecessors, but still distinctly as an advocate; for though he collected with great industry and gave impartially all the original facts (so that from what he gives alone it is quite possible to prove that the speech is certainly genuine), yet his own conclusions show great bias. Thus he severely rules out any testimony against Cresap that is not absolutely unquestioned; but admits without hesitation any and every sort of evidence leaning against poor Logan's character or the authenticity of his speech. He even goes so far (pp. 122, 123) as to say it is not a "speech" at all,--although it would puzzle a man to know what else to call it, as he also declares it is not a message,--and shows the animus of his work by making the gratuitous suggestion that if Logan made it at all he was probably at the time excited "as well by the cruelties he had committed as by liquor." It is necessary, therefore, to give a brief summary of a portion of the evidence in its favor, as well as of all the evidence against it. Jefferson's Notes and Mr. Mayer's book go fully into the matter.
