While Wilford Woodruff is preaching at John Benbow's Hill Farm to over 1,000 people, the local rector preaches to only 15. The rector sends a constable to arrest Elder Woodruff for preaching without a license. When the constable learns that he has a license, he sits and listens to the sermon and requests baptism at the end of the meeting. The next day the rector sends two more people to spy on Elder Woodruff's preachings, and both of them request baptism.
