Brother Moulthrop entered the Conference in 1840, and was first appointed to the Racine Mission.  In 1841 he was stationed at Troy, where he performed a vast amount of labor and gathered many souls for the Master.  He remained a second year and had for a colleague Rev. Henry Whitehead, so well known in connection with the Chicago Depository.  On coming to Waukesha he had Rev. S. Stover as a colleague.

At the close of his term Brother Moulthrop retired from the work, but was re-admitted to the Conference in 1859, it being conceded that so valiant a veteran should be permitted to spend the balance of his life in connection with the Conference.

Prairieville Circuit at this time extended from the lake towns to Watertown, and into Washington county as far as settlements had penetrated.  As stated in a former chapter, Brother Frink had passed over this region in 1839, and had formed classes during the Conference year at several places, but it now remained for his successors to extend the field.  In doing this Brother Moulthrop opened an appointment at Wauwatosa and in several other neighborhoods.

At Prairieville, the class formed by Brother Frink consisted of Mr. Owen, Leader, Mrs. Owen, Richard Smart, Truman Wheeler, Mrs. Truman Wheeler, Hiram Wheeler, Mrs. Hiram Wheeler, Theophilus Haylett and Horace Edsell, and to these were soon after added, Mr. and Mrs. Winters, Mr. and Mrs. Joseph Hadfield, Mr. and Mrs. Alexander Henry, Mr. and Mrs. Daniel Clark, Sarah Packham, Mr. Blodgett, Mr. and Mrs. John Bromell, John White, and Rev. Jonas Clark.  Brother Henry was soon after made the Leader.

The members of the class at Summit were John Merical, Leader, Levi Merical, John Merical, Jr., Philip Scheuler, Mary Scheuler, Maria L. Frink, Sarah Taft, and Sarah Hardell.

Prairieville charge was now in the Chicago District, and Rev. Hooper Crews was the Presiding Elder.  During this year he assisted Brother Moulthrop in holding a protracted meeting at Prairieville, and large numbers were converted.

Brother Crews was one of the choicest men in the Conference.  He began his ministerial work when what is now the great Northwest was yet in its infancy, and has mingled in the discussion and settlement of all the great questions which have arisen.  His appointments have placed him in the front rank of his compeers, and among them all, none have made a better record, or will go from labor to reward leaving a profounder regret among the people.

At the Milwaukee Conference in 1844, Prairieville charge was divided.  The northern portion was set off and erected into the Washington Mission, with Rev. J.M.  Snow as Pastor, of whom a record will be made in another chapter.  Brother Moulthrop remained on the old charge, and was able to take care of what remained without an assistant.

The following year, 1845, the charge again required two men, and Revs.  G.W.  Cotrell and Miles L. Reed were appointed, and had a year of great prosperity.  This year Pewaukee was detached from the Prairieville charge and added to Washington Mission, and as this change drew the latter to the southward, the name of Washington was dropped, and that of Menomonee substituted.  Brother Snow remained on the charge.
