5th While labouring for Elder J. Young in the latter part of the day we experienced a verry Sudden, hard, & rapid storm of wind and rain. A vane of it passed south of the temple in the form of a whirl wind or tornado. It destroyed and injured several buildings. It crushed one of Elder Young buildings instantly and removed the one we were in. Yet no lives were lost nor persons injured. Soon all was calm again.
