Section 63. Whoever, not being under seventeen, or a person asking charity within his own town, roves about from place to place begging, or living without labor or visible means of support, shall be deemed a tramp. An act of begging or soliciting alms, whether of money, food, lodging or clothing, by a person having no residence in the town within which the act is committed, or the riding upon a freight train of a railroad, whether within or without any car or part thereof, without a permit from the proper officers or employees of such railroad or train, shall be prima facie evidence that such person is a tramp.
