When we got to the top of the street, and turned north, we espied a crowd at the Tron Church. "A dog-fight!" shouted Bob, and was off; and so was I, both of us all but praying that it might not be over before we got up! And is not this boy-nature? and human nature too? and don't we all wish a house on fire not to be out before we see it? Dogs like fighting; old Isaac says they "delight" in it, and for the best of all reasons; and boys are not cruel because they like to see the fight. They see three of the great cardinal virtues of dog or man--courage, endurance, and skill--in intense action. This is very different from a love of making dogs fight, and enjoying, and aggravating, and making gain by their pluck. A boy,--be he ever so fond himself of fighting,--if he be a good boy, hates and despises all this, but he would have run off with Bob and me fast enough: it is a natural, and a not wicked interest, that all boys and men have in witnessing intense energy in action. Does any curious and finely-ignorant woman wish to know how Bob's eye at a glance announced a dog-fight to his brain? He did not, he could not, see the dogs fighting: it was a flash of an inference, a rapid induction. The crowd round a couple of dogs fighting is a crowd masculine mainly, with an occasional active, compassionate woman fluttering wildly round the outside and using her tongue and her hands freely upon the men, as so many "brutes;" it is a crowd annular, compact, and mobile; a crowd centripetal, having its eyes and its heads all bent downwards and inwards, to one common focus.
