I was used to horses and this one was frightened, that was all.
"Whoa, boy!" I ordered.

"Whoa! Stand still!" The horse had no intention of standing still.
He continued to rear and plunge.

I, clinging to the reins, found myself running alongside.

I had to run to avoid the wheels.

But I ran as slowly as I could, and my one hundred and ninety pounds made running, on the animal's part, a much less easy exercise.
The voice from the rear continued to shout and, in another moment, a man seized the reins beside me.
