Here [Lowell, Mass.] I found a branch of the Church of about 20 members in tolerable good standing. ... In this Branch there is a Coloured Brother, (An Elder ordained by Elder Wm. Smith while he was a member of the Church, contrary though to the order of the Church or the Law of the Priesthood, as the Descendants of Ham are not entitled to that privilege) by the name of Walker Lewis. He appears to be a meek humble man, and an example for his more whiter brethren to follow.
