". . . A company of Scandinavian emigrants bound for Zion, numbering 703 souls, sailed from Copenhagen, June 18, 1874, together with five returning elders, namely, Peter C. Carstensen, Christian F. Schade, Peter C. Christensen, Mathias B. Nilsson and Jens Hansen. The first company of 517 souls left by the steamer 'Milo' and arrived safely in Hull, England, Monday, June 22nd, in the forenoon and the same day were taken by rail to Liverpool. Another company of 186 souls, in charge of Elder Christian F. Schade, left on the steamer 'Humber' and had a hard voyage across the North Sea on account of rough weather, for which reason the captain ordered a lot of cattle to be thrown overboard; but the ship arrived nevertheless safely at Hull on the 22nd in the evening, and on the following day the emigrants arrived by train in Liverpool, where all the Scandinavian Saints, together with a number of other emigrants, went on board the steamer 'Idaho,' which sailed from Liverpool on Wednesday afternoon June 24th. There were 810 Saints on board and about 300 other emigrants, who occupied the forepart of the ship. Elder Peter C. Carstensen was appointed leader of the company with Elders John Clark and George F. Gibbs as his assistants. With the exception of one stormy day, the weather was favorable all the way. On that day the waves rolled like mountains, and a mighty wave rushed over the deck, and (the hatchway happening to be open) a great volume of water went down below, so that mess boxes, baskets and the like were seen floating about, while the passengers were forced into the bunks till the water was pumped out. A remarkable calm was observed among the Saints on that occasion, while the opposite was the case with the other passengers, who were badly frightened. Captain Forsyth, relating the occurrence on the following morning at the breakfast table, said that he went down to the people in the forepart to allay their fears, as they were crying aloud, 'Lost, we are lost!' But after he had assured them that there was no danger, because there were too many 'Mormons' aboard for the ship to be harmed, order and quiet was restored. A Catholic priest, who was present, took exception to this statement, but the captain said that he had now for 18 years conveyed the 'Mormons' safely across the Atlantic, and he had never heard of the loss of any ship carrying 'Mormons.'
On the 6th of July the company arrived safely in New York and on the following day proceeded by rail from Jersey City westward, arriving in Ogden and Salt Lake City, all safe, on the 15th of July. Two children had died of measles on the journey. . . ."
