At this moment, apparently from some upper region, there burst forth an uproar so sudden and overwhelming that it might well have been taken for a premature testing of a large sample of Partridgite; until a moment later it began to resemble more nearly the shrieks of some partially destroyed victim of that death-dealing invention. It was a bellow of anguish, and it poured through the house in a cascade of sound, advertising to all beneath the roof the twin facts that some person unknown was suffering and that whoever the sufferer might be he had excellent lungs. The effect on the gathering in the drawing-room was immediate and impressive. Conversation ceased as if it had been turned off with a tap. Twelve separate and distinct discussions on twelve highly intellectual topics died instantaneously. It was as if the last trump had sounded. Futurist painters stared pallidly at _vers libre_ poets, speech smitten from their lips; and stage performers looked at esoteric Buddhists with a wild surmise. The sudden silence had the effect of emphasising the strange noise and rendering it more distinct, thus enabling it to carry its message to one at least of the listeners. Mrs. Pett, after a moment of strained attention in which time seemed to her to stand still, uttered a wailing cry and leaped for the door. "Ogden!" she shrilled; and passed up the stairs two at a time, gathering speed as she went. A boy's best friend is his mother. CHAPTER X INSTRUCTION IN DEPORTMENT While the feast of reason and flow of soul had been in progress in the drawing-room, in the gymnasium on the top floor Jerry Mitchell, awaiting the coming of Mr. Pett, had been passing the time in improving with strenuous exercise his already impressive physique. If Mrs. Pett's guests had been less noisily concentrated on their conversation, they might have heard the muffled _tap-tap-tap_ that proclaimed that Jerry Mitchell was punching the bag upstairs. It was not until he had punched it for perhaps five minutes that, desisting from his labours, he perceived that he had the pleasure of the company of little Ogden Ford. The stout boy was standing in the doorway, observing him with an attentive eye. "What are you doing?" enquired Ogden. Jerry passed a gloved fist over his damp brow. "Punchin' the bag." He began to remove his gloves, eyeing Ogden the while with a disapproval which he made no attempt to conceal. An extremist on the subject of keeping in condition, the spectacle of the bulbous stripling was a constant offence to him. Ogden, in pursuance of his invariable custom on the days when Mrs. Pett entertained, had been lurking on the stairs outside the drawing-room for the past hour, levying toll on the food-stuffs that passed his way. He wore a congested look, and there was jam about his mouth. "Why?" he said, retrieving a morsel of jam from his right cheek with the tip of his tongue. "To keep in condition." "Why do you want to keep in condition?"
