must

“No animal in the world is so dangerous as an elephant in must.”

“Early one morning the sub-inspector at a police station the other end of the town rang me up on the 'phone and said that an elephant was ravaging the bazaar. Would I please come and do something about it? […] It was not, of course, a wild elephant, but a tame one which had gone "must". It had been chained up, as tame elephants always are when their attack of "must" is due, but on the previous night it had broken its chain and escaped.”
