_ 61 Ibid._, 72, 73, 74. Boyd states in “Am. Hist. Rev.,” IV., 632, 635, that the county ceased to exist in 1781. This is erroneous. Mr. Boyd’s article is the most scholarly treatment of the County of Illinois which has been published. Aside from the errors as to the time of the beginning and the ending of the county, and doubtful statements as to Todd’s leaving Illinois and subsequently resigning, no errors of fact have been noted. A more complete, but unpublished, article on the subject is by Dr. Edith Lyle. 62 Sinclair to Haldim, from Michilimackinac, Feb. 17, 1780—“Mich.
