Gone in a flash

Getting lost in Twain's amusing Roughing it 

Carriage rattling in the praries enduring a female chatterbox,

later come across a jackrabbit, huge ears taller than a fox 

they scare him by shooting, 

flattening ears he responds by scooting,

hopping over bushes, gone in a flash

thirty five miles an hour, faster than a horse, some dash

We have them here too they're hares
