Probably The Nautical Almanac and Astronomical Ephemeris published by the Lords Commissioners of the Admiralty in Great Britain. (See, for example, The Nautical Almanac and Astronomical Ephemeris for the Year 1846 [London: William Clowes and Sons, 1842].) These almanacs consisted of astronomical figures and charts to be used for navigation. Pratt had a growing interest in almanacs. The previous summer, he published an almanac for 1845, and during the summer of 1845 he published an almanac for 1846. (Crawley, Descriptive Bibliography, 1:269–272, 308.)

Rigdon spent much of February 1845 in Kirtland, Ohio, preaching to large audiences at the Kirtland temple and organizing a congregation there. He was joined by other prominent Mormon dissenters, including William Law and William E. McLellin, in preaching at Kirtland. According to Rigdon’s account, these activities led to some conflict with local Latter-day Saints who endorsed the leadership of the apostles. (Sidney Rigdon, Letter to the Editor, Latter Day Saint’s Messenger and Advocate [Pittsburgh], 15 Mar. 1845, 145–146.)

Rigdon and his followers published the Latter Day Saint’s Messenger and Advocate (later named Messenger and Advocate, of the Church of Christ), with the first issue dated 15 October 1844 from Pittsburgh. The paper sought to expose conditions “as they exist at the present time among the Saints, particularly at Nauvoo,” including the practice of polygamy and other allegations against the Quorum of the Twelve Apostles. These exposés were quoted by opponents of the church. Thomas Sharp, for example, occasionally reprinted articles from Rigdon’s paper in the Warsaw Signal, noting that “it is by far the ablest edited Mormon Periodical we have ever seen and it scores the Twelveites without mercy.” (John A. Forgeus to Samuel L. Forgeus, 25 Sept. 1844, in Latter Day Saint’s Messenger and Advocate [Pittsburgh], 15 Oct. 1844, 10; “Spiritual Wife System,” Warsaw [IL] Signal, 29 Jan. 1845, [1].)
