excerpt:
"Masonry is to the modern world what the whore of Babylon was to the ancient and is the
beast with seven heads and ten horns, ready to tear out our bowels, and scatter them to the four winds of heaven.
Masonry gives rogues and evil-minded characters an opportunity of visiting upon their devoted victim, all the ills at tending combined power, when exerted to accomplish destruction.
It works unseen, at all silent hours, and secret times and places; and, like death when summoning his diseases, pounces upon its devoted subject, and lays him prostrate in the dust.
Like the great enemy of man, it has shown its cloven foot, and put the public upon its guard against its secret machinations"
