Already a low undertone of protest and complaint against the seven o'clock bell is being heard from the dwellers in the Yard. Communications and denunciations will soon appear in their annual abundance. The justification of this old custom is to be found in the fact that it is successful in calling forth words of execration and condemnation. The Senior requires something upon which to vent his discontent, and then it distracts his mind from harmful meditation on the probable results of the world war, or the possibilities of more comprehensive knowledge of the fourth dimension. As David Harum says, "A certain amount of fleas is good fer a dog, it keeps him from worryin' about bein' a dog."
Perhaps the "gentlemen higher up" find this a sufficient justification for the custom.
