"DEPARTURE OF THE SHIP UNDERWRITER. -- The ship Underwriter, Captain Roberts, cleared on Wednesday the 28th of March, and sailed for New York on Friday the 30th. There were on board 594 souls of the Saints, under the presidency of Elder James D. Ross, assisted by his counsellors, James Taylor and John Croft. This number included 70 souls from Switzerland, and the remainder from the British Mission. Nearly the whole of this emigrating company of Saints are en route direct for Utah, the home of the Saints. God speed and bless them abundantly on their journey!"
