   I have already alluded to "strawing," which can hardly be described as quackery. It is rather a piece of mountebankery. […] The strawer offers to sell any passer by in the streets a straw and give the purchaser a paper which he dares not sell. Accordingly as he judges of the character of his audience, so he intimates that the paper is political, libellous, irreligious, or indecent.
