Buffalo Grass.—(Buchloë dactyloides Engelm), a species of low, fine-leafed creeping perennial, rarely growing more than 4 to 6 inches high, was once very plentiful on the western plains. It grew on the dry prairies and river bottoms from South Dakota to Texas, attained its growth early and cured long before frost time, preserving all its nutriment and forming the principal forage of the buffaloes during winter. It seemed to thrive best where most trampled. As the plains country settled up, and tame grasses have been introduced the buffalo grass has gradually disappeared, the newer varieties crowding it out.
