"My visit to Oregon was one of special interest. I here met, after a separation of four years, my dear friends, Brother and Sister Van Horn, whom we claim as our children. Brother Van Horn has not furnished as full and favorable reports of his work as he might justly have done. I was accordingly somewhat surprised, and very much pleased, to find the cause of God in so prosperous a condition in Oregon.
