It was one of those abnormally springlike days that New York sometimes experiences at the latter end of March, days when negligee shirts and last summer's straw hats make a sporadic appearance, and bucolic weather prophets write letters to the afternoon papers abusing the sun-spots. Really, it was hot, and I was anxious to get out of the dust and glare; it would be cool at the club, and I intended dining there. The time was half-past six, the height of the homeward rush hours, and, as usual, there was a jam of vehicles and pedestrians at the Fourth Avenue and Twenty-third Street crossing. The subway contractors were still at work here, and the available street space was choked with their stagings and temporary footwalks. The inevitable consequent was congestion; here were two of the principal thoroughfares of the city crossing each other at right angles, and with hardly enough room, at the point of intersection, for the traffic of one. The confusion grew worse as the policemen and signalmen stationed at the crossing occasionally lost their heads; every now and then a new block would form, and several minutes would elapse before it could be broken. In all directions long lines of yellow electric cars stood stalled, the impatient passengers looking ahead to discover the cause of the trouble. A familiar enough experience to the modern New-Yorker, yet it never fails to exasperate him afresh.
