President & sister E. [Emma Smith] rode up to Temple [to be baptized] for the benefit of her health she is rapidly gaining. ... When going down the hill near Caspers the carriage got overbalanced and upset. President Joseph was thrown some distance from the carriage and the children all three almost under it. He arose and enquired if any of the children were killed but upon examination there was no one seriously hurt, Frederic G. W. [Frederick Smith] had his cheek bruised which was about the worst injury received. ... It seemed miraculous how we escaped serious injury from this accident.
