Apparently some Saints were questioning the right of the Twelve to replace the wooden font which had been built under Joseph Smith's directions. In the Times and Seasons Brigham Young explained the reason for erecting the stone font and he wrote that the Saints should not wonder at the decision. Just because Joseph Smith had built, a wooden font did not mean that it should be permanent. He stated that he wanted a font that would not "stink" and take so much time in keeping it clean.
