Again I pressed the lean ribs under me.
"After the spotted leopardess!" I whispered in his ear.
He turned his head this way and that, snuffing the air; then started, and went a few paces in a slow, undecided walk.

Suddenly he quickened his walk; broke into a trot; began to gallop, and in a few moments his speed was tremendous.

He seemed to see in the dark; never stumbled, not once faltered, not once hesitated.

I sat as on the ridge of a wave.

I felt under me the play of each individual muscle: his joints were so elastic, and his every movement glided so into the next, that not once did he jar me.
