During the last three years of his life, Zeb entered a period of gradual political and physical decline. While evidence of his slow loss of influence and energy was obvious at various times, the fact that his health was declining was masked by bursts of accomplishment. It is important to recognize that at this time there was a fundamental historical shift that would have undermined Zeb's political position whether he had been in good health or not.

There is very little direct evidence as to what his physical problems were, but the best existing evidence indicates that all of the pressure associated with his reelection campaign caused a recurrence of the symptoms that had plagued him two years earlier.

Zeb admitted that he had experienced enough seasickness on the journey "to satisfy any curiosity that I may have felt." He told another correspondent that he had thrown "up everything except my seat in the Senate!" The party landed at Queenstown in Ireland and traveled rapidly through Cork, Killarney, Dublin, and Belfast. When they reached Ulster, Florence and Harry continued on to the west coast, where the family home of Florence's first husband was located. Florence proved to be an avid tourist, and she loved Ireland. Apparently she suffered a number of scrapes and falls during the trip, but she was not
