He was resting, and gazing about him, when the wagon driver came up. The driver was a colored youth in a khaki shirt and an overseas cap, and his wagon was a horseless affair, huge and covered. The colored man, halting his truck to let a cross current of vehicles pass, dazzled Johnnie with a good-natured smile. Johnnie grinned back. "You goin' up Broadway?" he asked, with a jerk of his head toward the north. "All the way up t' Haa'lem," answered the black man, cordially. "Climb aboa'd!" There was a loop of chain hanging down from the end-board of the truck. Johnnie guided a foot through it stirrup-wise and reared himself into an empty wagonbed. Then as the wheels began to turn, he faced round, knelt comfortably, and let Broadway swiftly drop behind. He could not see all the new and engrossing sights that offered themselves in the wake of the truck and to both sides. His ears were packed with strange noises. Yet entertained as he was, from time to time he took note of the cross streets--Eighth, then Tenth, next, busy Fourteenth. From time to time the colored man took note of him. "You-all thay yit?" he would sing out over a shoulder; or, "Have Ah done los' you, kid?" Upon being reassured, he would return to his problem of nosing a way along with other vehicles, large and small, and Johnnie would once more be left to his fascinating survey. At Twentieth, he very nearly fell out on that shining head, this at catching sight of a mounted patrolman. No figure in his beloved book seemed more splendid to him than this one, so noble and martial and proud. Here was a guardian of the peace who was obviously no common mortal. Then and there, as the mounted dropped gradually into the background, Johnnie determined that should he ever be rich enough, or if hard work and study could accomplish it, he would be a mounted policeman. At Twenty-third Street, Broadway suddenly took a sharp turn--toward the right. Also, it got wider, and noticeably cleaner. More: suddenly confronted with the gigantic, three-cornered building standing there, a structure with something of the height and beauty of his own dream edifices, he realized that he was now entering the true New York. This was more like it! Here was space and wealth and grandeur. Oh, how different was this famous street from either of those which gave to the building in the area! Then he discovered that he was not traveling a street at all! He was skimming along an avenue. And it was none other than Fifth Avenue, for the signs at corners plainly said so. Fifth Avenue! The wonderful, stylish boulevard which Cis mentioned almost reverently. And he was in it!
