DEPARTURE OF MISSIONARIES.—Yesterday morning, a number of our missionary friends, including Elders W. S. Warren, W. B. Preston, W. R. Smith, A. N. Hill, W. Gibson, C. W. Penrose, W. A. McMaster, F. C. Anderson, and Elias Morris, left the city on their way to Europe. We understand they intend taking the "upper road," via Laramie, expecting that feed will be more plentiful on that route. From our knowledge of these gentlemen, we anticipate a good time for them and the cause of the mission on which they are engaged.
