I had much ado, though I bit my Lip, to forbear Laughing at so pleasant a Punishment; and therefore to take me off of this odd piece of Pedantick Discipline, which, without doubt, would have made, me burst out at last; I prayed my Philosopher to tell me what he meant by that Journey of the Town he talked of, and if the Houses and Walls Travelled? "Dear Stranger," answered he, "we have some Ambulatory Towns, and some Sedentary; the Ambulatory, as for instance this wherein now we are, are Built in this manner: The Architector, as you see, builds every Palace of a very light sort of Timber; supported by four Wheels underneath; in the thickness of one of the Walls he places ten large pair of Bellows, whose Snouts pass in a Horizontal Line through the upper Story, from one Pinacle to the other; so that when Towns are to be removed from one place to another, (for according to the Seasons they change the Air) every one spreads a great many Sails upon one side of the House, before the Noses of the Bellows; then having wound up a Spring to make them play, in less than Eight days time their Houses, by the continual Puffs which these Windy Monsters blow, are driven, if one pleases, an Hundred Leagues and more. "For those which we call Sedentary, they are almost like to your Towers; save that they are of Timber, and that they have a Great and Strong Skrew or Vice in the Middle, reaching from the top to the Bottom; whereby they may be hoisted up or let down as People please. Now the Ground under neath is dugg as deep as the House is high; and it is so ordered, that so soon as the Frosts begin to chill the Air, they may sink their Houses down under Ground, where they keep themselves secure from the Severity of the Weather: But as soon as the gentle Breathings of the Spring begin to soften and qualifie the Air; they raise them above Ground again, by means of the great Skrew I told you of."
