The last of the capital sunstones were placed on the [Nauvoo] temple walls. There were problems in raising the stone, causing a delay of an hour and a half, when it was finally placed at 10:30 a.m., which closed the construction season for 1844. The last stone had been cut by Harvey Stanley. Twelve of the capitals were still lacking their trumpet stones, which would not be placed until the following spring. The Saints viewed the late arrival of winter as divine assistance in their labors; the season's first snow storm commenced just two hours after the last sunstone was placed. By morning there was four inches of snow on the ground.
