The only germ in their constitution from which the "Imperial Wizard" Simmons of the twentieth century Klan could breed his present organization was the promise of absolute secrecy. For his copying years later, the first Klan also contrived a disguise. It consisted of a white mask, a tall cardboard hat, a gown or robe, and for the night riding excursions, a cover for the horses' bodies and mufflers for their feet. Only after the Pulaski organization had entertained itself for many nights did the phenomenon present itself which was to make the Klan a weapon in the progress of post-war reconstruction. It was the discovery that the African negro was twice as fearful of mysticism and mystery as the white man. It taught the white men of Tennessee and neighboring states that they had a means of their own of preventing what they considered political mismanagement and social insolence in the control by northerners and freedmen of the state government. BECOMES MILITARY ORGANIZATION The Pulaski riders made themselves popular. Young men of neighboring towns organized brother Klans. When southern society found itself a Humpty Dumpty fallen from the wall, it grasped the Pulaski idea as the means for pulling itself up again. The Klan became a military organization, with the purpose of keeping order among the negroes by intimidating them. Mysticism in the order grew. Humor grew with it, and by the time the states of the north discovered that the south had an organization which was in purpose a society of regulators, the young southern war veterans were donning their white robes and cardboard hats with a human skull and two thigh bones as the symbols of allegiance. The oath which the grand cyclops administered has been preserved in southern diaries and documents. It was taken in a solemn manner as the knights were grouped amid the bones. The oath follows. "We (or I, as the case might be) do solemnly swear before Almighty God and these witnesses, and looking upon these human bones, that I will obey and carry into effect every order made by any cyclops or assistant cyclops, and if I fail strictly to conform and execute every order made, as above required of me, unless I am prevented from some cause which shall be no fault of mine, or if I shall give any information to any person or persons except members of this order, that the doom of all traitors shall be meted out to me, and that my bones may become as naked and dry as the bones I am looking upon. And I take this oath voluntarily, without any mental reservation or evasion whatever, for the causes set out in said order, so help me God." Ku-Klux horsemen who rode white-sheeted through the south in the nights of 1866 regarded themselves as upholders of sectional patriotism.
