James Greenwood, Stirring scenes in savage lands (1865)
“ The signal is given, the war-song commences, and the mass moves simultaneously as if it were but one man. Every arm is in motion; every head turns at once; the feet of all strike the ground in time with such force that the vibration is felt for more than two hundred yards. Every muscle is in movement; every feature distorted; the most gentle countenance assumes a ferocious and savage expression. The more violent the contortions, the more beautiful the dance is considered. ”
