We now exercise animals before breakfast.  Trumpet!

When you want to do anything to a touchy animal which he is likely to resent, you commence by putting what is called a “twitch” on his lip, i.e. a stout stick with a loop of cord or leather on one end, the loop being slipped over his upper lip and twisted up tight by the handle.  When his lip is pinched up into a bulb he is practically helpless, losing interest in everything in the world except lip which he eyes askance in pained suspense until released.
