"After them!" shouted Mr. Graham, and instantly the hunters spurred on their horses many of which were used to the sport, and in a few minutes Guy, who was poorly mounted was left some distance in the rear, while the foremost of the horsemen were at the very heels of the flying herd. The dust of the prairie began to rise from beneath their hoofs in clouds, through which Guy could indistinctly see the buffaloes dashing forward, one turning occasionally upon some audacious man who had fired upon him, who would then wheel his horse quickly and escape from the reach of the infuriated animal, which would continue its flight or fall to the earth, with a terrible bellow.
