And it shows in the distance, by reason of the mixed uniforms and standards, a totally chaotic mass of men, heaped one on another. But it needs only that the commander lift his finger, and instantly this living coil of knotted intricacies develops itself in perfect order, and with a speed like that of mountain rivers.112
