"Considered in the world of physics," began the lordly tones of the Reverend Frederick, "dynamics is that branch of mechanics that treats of the effects of forces in producing motion, and of the laws of motion thus produced; sometimes called kinetics, opposed to statics. It is the science that treats of the laws of force, whether producing equilibrium or motion; in this sense including both statics and kinetics. It is also applied to the forces producing or governing activity or movement of any kind; also the methods of such activity."
The big words rolled out magnificently over the awed gathering, and the minister flattened his chin and rolled his eyes up at the people in his most impressive way.
Margaret's gaze hastily sought the row of rough men on the front seat, sitting with folded arms in an attitude of attention, each man with a pair of intelligent eyes under his shaggy brows regarding the preacher as they might have regarded an animal in a zoo. Did they understand what had been said? It was impossible to tell from their serious faces.
"Philanthropy has been called the dynamics of Christianity; that is to say, it is Christianity in action," went on the preacher. "It is my purpose this morning to speak upon the dynamics of altruism. Now altruism is the theory that inculcates benevolence to others in subordination to self-interest; interested benevolence as opposed to disinterested; also, the practice of this theory."
He lifted his eyes to the audience once more and nodded his head slightly, as if to emphasize the deep truth he had just given them, and the battery of keen eyes before him never flinched from his face. They were searching him through and through. Margaret wondered if he had no sense of the ridiculous, that he could, to such an audience, pour forth such a string of technical definitions. They sounded strangely like dictionary language. She wondered if anybody present besides herself knew what the man meant or got any inkling of what his subject was. Surely he would drop to simpler language, now that he had laid out his plan.
It never occurred to her that the man was trying to impress her with his wonderful fluency of language and his marvelous store of wisdom. On and on he went in much the same trend he had begun, with now and then a flowery sentence or whole paragraph of meaningless eloquence about the "brotherhood of man"--with a roll to the r's in brotherhood.
Fifteen minutes of this profitless oratory those men of the wilderness endured, stolidly and with fixed attention; then, suddenly, a sentence of unusual simplicity struck them and an almost visible thrill went down the front seat.
