Sometime I contriv'd to dig a Hole under the Place where they made their Fire, and put in five or six Pound of Gun-powder, which when they kindled their Fire, would consequently take Fire, and blow up all that was near it; but as in the first Place I should be very loth to wast so much Powder upon them, my Store being now within the Quantity of one Barrel; so neither could I be sure of its going off' at any certain Time, when it might surprise them, and at best, that it would do little more than just blow the Fire about their Ears and fright them, but not sufficient to make them forsake the Place; so I laid it aside, and then propos'd, that I would place my self in Ambush, in some convenient Place, with my three Guns, all double loaded; and in the middle of their bloody Ceremony, let fly at them, when I should be sure to kill or wound perhaps two or three at every shoot; and then falling in upon them with my three Pistols, and my Sword, I made no doubt, but that if there was twenty I should kill them all: This Fancy pleas'd my Thoughts for some Weeks, and I was so full of it, that I often dream'd of it; and sometimes that I was just going to let fly at them in my Sleep.

Peter's headship was as much emphasized by Christ Himself, and was as clearly recognized in the infant Church, as was the enduring authority of the episcopal body; and it is a puzzle which the Catholic finds it hard to solve, how those who deny that the supreme authority of Peter's successor is an essential factor in the constitution of the Church can consistently maintain the Divine authority of the episcopate.
