Harry Buck, born in New York State, preached for the Wesleyan Methodists for several years before he and Jane became Sabbathkeepers about 1852. From 1854 to 1859 Buck preached widely, together with other evangelists, in New York, Vermont, and Canada East. Problems seem to have attended his work, however, for in 1861 Ellen White wrote him a very frank letter regarding his unwillingness “to learn or submit to your brethren” and his, at times, “harsh, hard spirit.” The upshot of the letter was that “in your present condition … [God] will not accept your labors.” Some months later Harry Buck confessed his faults publicly through a letter to the Review editor, but there is no evidence that he returned to itinerant ministry. He did, however, remain an active church member for the rest of his life, first in Buck's Bridge church, New York, where he was ordained as an elder in 1862, and, from about 1864, in the Monterey, Michigan, church. 1EGWLM 799.1
