But he went straight ahead as it looked to be the safest course. The savages, like a pack of wolves, came yelling on behind.

It was easy for the Steam Horse, however, to keep ahead of them.

If it had been daylight Barney could have amused himself giving the savages a wild chase.

But it was so exceedingly dark that he dared not go too fast.

Pomp kept up his destructive fire just the same, and the savages dropped at every shot.

On and on in the night ran the Steam Horse.

Fortunately thus far they had encountered no obstacle.

The course had been perfectly smooth, with scarcely a pebble to jar them.

But Barney could not hope for this to last.

It seemed as if they had covered several miles when a startling thing happened.
