A great cry of horror now went up from Frank and Barney.
The mustang was seen racing along the edge of a mighty chasm. In a few seconds he would be almost sure to take an impossible leap over a deep gorge.
If he should go to the bottom of that gorge it would be the end of Pomp and the mustang.
This was seen at a glance and with the most intense of horror Barney cried:
“Shall I fire, Misther Frank? It’s the only thing as will save the naygur.”
“You will have to do that,” replied Frank, sharply. “Look out for your aim, Barney. God help Pomp!”
Barney pulled the trigger.
Crack!
The bullet sped true to its mark. It struck the mustang in the side.
The animal faltered, threw up its head, stumbled, and then pitched forward in a heap.
