The Spring Bok is found throughout the whole of South 
Africa, but in no part so numerously as in the colony, the north- 
eastern division of which they traverse in herds of thousands, 
devouring everything they meet with in their course. They re- 
main only a portion of the year, and it is during that season the 
Lion is most frequently found there. Vast numbers are killed, 
and the flesh dried against a season of scarcity.—A. Smith. 
The Springbock at certain periods make a trak bokken or 
grand migration. They march slowly and steadily along, like the 
flood of a river, about half a mile in width. These vast legions 
will continue streaming along in an unbroken, compact phalanx 
for two or more hours.—R. G. Cumming, Hunter’s Life, 1. 122.
