Looking down upon the Avenue, at the corner of Thirty-third Street, just below the Waldorf, are familiar windows. They belonged to a hotel that was, or is, the Cambridge, and in the rooms behind the windows, I recall occasional pleasant and profitable hours spent in the company of Richard Harding Davis. There was another window some blocks farther down, in the building occupying the point where Fifth Avenue and Broadway join. That window gave light to the workshop of James L. Ford, the obstinate satirist, who resents the charge of amiability, and who will not be pleased if you tell him that in the pages of "The Literary Shop" he did the best work of his life. At another corner, between the two already mentioned, the early riser of a few years ago might have seen the literary pride of Indiana assuming the duties of the traffic policeman who had not yet reached his post, and with the aid of a whistle joyously acquired ordering east and west-bound vehicles to proceed and north and south-bound vehicles to halt. If you know your Avenue well enough, the countenances of nearly all of the "Best-Selling" kings are easy of recognition. Arriving at the Thirties, Robert W. Chambers is likely to turn off, bound for one of the antique shops that are to be found in the parallel thoroughfare two blocks to the east. At any point on the Avenue between the Washington Arch and the Plaza you may stumble upon the cane-swinging discoverer of the principality of Graustark, and the cane-swinging inventor of the "Tennessee Shad," appraising together the new styles in women's hats, or investigating the display in a shop-window. What is the subject that they are so earnestly discussing? The Influence of Rabelais on the Monastic System of the Fifteenth Century? The obscurity of Robert Browning? Whether or not the art of the novel is a finer art than it was in the days of the Victorians? Not at all. The point in dispute is the figure of Delehanty's batting average in 1867. The vital importance of the matter is the reason of their obvious excitement.
