I grew up in Arkansas, from 1937 until I left in 1962. I never heard of the name of the state being spelled OFFICIALLY, "Arkansaw." My great, great grandfather was a U.S. Congressman from Arkansas, and I have a book from his library entitled, "The Constitution of the United States," which among other things, gives the admission dates of all the states, to that time, into the Union, spells the name, "Arkansas." This book was given to all members of Congress and was published in 1846.
There was a song called, "The Arkansaw Traveler," and a scurrilous book, supposed to be "hahahaha funny," written by Bob Burns, in the '30s, which had the term "Arkansaw," in the title. It denigrated the state and its inhabitants, and gave a false image of the state to outsiders that everyone there was a backwards, barefoot hillbilly, which was difficult to overcome.
If one looks on old maps, one sees the name of the state spelled "Arkansas," and the great river that runs through it, the "Arkansas River." I mean old maps of the 1850s vintage... which I have. Or look at the reproduction maps of the War For Southern Independence, and you'll see the correct spelling. Ad infinitum.
Anyone can put anything he wants on a knife, but the official spelling of the state's name has ALAWYS been "Arkansas."
Just thought you Arkansas boys would like to know.
