On Monday, May 28, 1877, the work of excavation was begun. Workmen were supplied by wards of the Logan Temple District, which at that time comprised the Cache, Box Elder, and Bear Lake Stakes of Zion. Besides giving of their time and energy,--gifts known as labor donations,--the people contributed freely of cash, livestock, merchandise, and farm produce, and their contributions were supplemented by liberal appropriations from the general Church funds. Truman O. Angell, Jr., was the architect. Rock-laying began on July 20, 1877, on what was known as the extension--a building eighty feet by thirty-six feet in area and twenty-three feet high, lying immediately north of the Temple proper and connected therewith; this has been used since the completion of the Temple for engine room, office, reception, and assembly rooms, thus corresponding to the Annex of the Temple in Salt Lake City. On September 19, 1877, the corner stones were laid under the immediate direction of John Taylor, president of the Council of the Twelve. President Taylor laid the south-east corner stone and Franklin D. Richards offered the dedicatory prayer thereon. The south-west corner stone was laid by Edward Hunter, Presiding bishop of the Church, and the dedicatory prayer thereon was offered by his counselor, Leonard W. Hardy. The north-west corner stone was laid by George L. Farrell, president of {220} the High Priests' quorum of the Cache Stake of Zion, and the accompanying prayer was offered by Moses Thatcher, of the Council of the Twelve. The north-east corner stone was laid by Albert P. Rockwood, one of the First Council of the Seventy, and the accompanying prayer was offered by Horace S. Eldredge, another member of the First Council of the Seventy. The Temple as it stands is one hundred and seventy-one feet long, ninety-five feet wide, and eighty-six feet high at the square, with an octagonal tower at each corner one hundred feet high, and a large square tower at each end. The tower at the west end is one hundred and sixty-five feet, and that at the east one hundred and seventy feet high. In this feature of the east tower being higher than that at the west the Logan Temple resembles the greater structure at Salt Lake City. Massive buttresses strengthen the walls, and the masonry is of the best. As to architecture, the Temple may be described as belonging to the castellated style.
