Sentence:  It at once became abundantly manifest, that those six <WSD>Peelers</WSD> had arrived with some object in view; and before the Sovereign People had time even to guess what that object might be, one of the Peelers very coolly depreived the horse of his nose-bag; another just as coolly returned the bit to his mouth; and a third, with equal coolness, go hold of the reins, when a fourth, who was certainly not quite so cool, did, by virtue of the application of a short round truncheon, persuade the passive animal to move on.
