Every peddler shall furnish the judge of the probate court with evidence of his good character and shall take and subscribe before him this oath:

"I swear that I will use this license in no county other than the one for which it is granted, that I will not suffer any person to use it in my name, and that I am a citizen of this state. So help me God."

Such oath and license shall be entered in the book kept for that purpose. The license shall contain a physical description of the peddler.
