I had sprung to one side to let it go by when I heard a man's voice shouting, "Whoa!" The voice did not come from the carriage but from the road behind it.
"Whoa! Stop him!" it shouted.
I jumped back into the road.

The horse saw me appear directly in front of him, shied and reared.

The carriage lamps were lighted and by their light I saw the reins dragging.

I seized them and held on.

It was all involuntary.
