I learned today that our archives has received some of the papers of A. Hamer Reiser who was formerly secretary of the First Presidency of the Church. ... Brother Affleck suggests that "It would be conservative to say that the $26 million-plus was spent on purchases and services in the communities of Utah to an additional 2,000 persons or firms." In other words, he summarized, "at least 3,000 persons and firms in Utah did business with the Church in 1960 for a total of $44,847,000."
