“I thought I saw a specimen of the almost extinct herds of buffalo,” answered the naturalist.
“Buffalo!” cried Nestor, standing up to get a good view. “That’s the other automobile you see!”
“So it is!” admitted the professor, taking a second glance.
“Put on all the steam you’ve got!” cried the miner. “We must catch them before night or the mine is lost! We’re close to it now!”
Jerry opened the throttle wide and shortened the intervals of sparking. The automobile fairly jumped ahead, but so rough was the road that the travelers were bounced about like peas in a pod.
“We’re gaining on them!” Ned shouted. “We’ll soon be up to them!”
In a little while not more than an eighth of a mile separated the two machines, and this distance was gradually being lessened. Stoneham and Dalsett, who were in the rear seat, looked back and shook their fists.
“Not very pleasant chaps,” commented Nestor. “Well, we don’t mind how they look.”
