Specific plans to preach the restored gospel in the west matured during the second conference after Church organization, held late September, 1830. The missionary theme was prominent during the three-day duration of this conference. The official minutes summarize what was probably the first missionary farewell in LDS history: "Singing and prayer in behalf of Brother Oliver Cowdery and Peter Whitmer, Jr., who were previously appointed to go to the Lamanites." The Ohio labors of Oliver Cowdery, Parley P. Pratt, and their companions doubled the membership of the Church and created a solid nucleus for rapid growth and a secure, if temporary, gathering location. One must assess the impact of these four men in four weeks with a certain awe.
