He attended the meeting where Sidney Rigdon asked the Saints to appoint him as guardian, and where Brigham Young claimed that the Twelve Apostles were the ordained leaders; and many times thereafter he testified that he saw Brigham Young changed to appear like Joseph and heard his voice take on the Prophet's tone. And after that manifestation he never doubted for a moment that the rightful leadership of the Church was vested in the twelve, with Brigham Young at their head. He remained in Nauvoo till almost the last departed. He assisted Browning in transforming the old rusty steamer shafts into cannons that were so effectually used by Daniel H. Wells at the Battle of Nauvoo.
Leaving Nauvoo with the last of the Mormon exiles, he crossed Iowa and settled at Pisgah, where he served as counselor to Lorenzo Snow, President at Mt. Pisgah. In his devoted attachment to Lorenzo Snow, he was an enthusiast; also to Father Morley and he would follow their leadership anywhere. Orville and Elvira had their two children, Almer and Adelia.
An incident that illustrated the pioneer life of 1845-6 is told in the story of the "Last Match." In the winter of 1845-6 Orville S. Cox and two Whiting boys, cousins of Elvira, went from Pisgah with ox teams and wagons down into Missouri with a load of chairs to sell. Whitings had a shop in which they manufactured chairs. Being successful in disposing of their chairs, and securing loads of bacon and corn, they were almost home when an Iowa blizzard, or hurricane, or cyclone, or all in one, struck them. Clouds and Egyptian darkness settled suddenly around them. They had not modern "tornado cellars" to flee into and no manner of shelter of any kind. The cold was intense; the wind came from every direction; they were all skilled backwoodsmen and knew they were very close to their homes; but they also knew that they were hopelessly lost in that swirling wind and those black clouds of snow. They and their oxen were freezing, and their only hope of life was in making a fire and camping where they were. Everything was wet and under the snow, and an arctic wind in the fierceness of unclaimed violence was raging around them. At first, they unyoked the oxen that they might find some sort of shelter for themselves. Then with frost-bitten fingers they sought in the darkness and storm for dry fuel. The best they found was damp and poor enough—and now for a match. Only three in the crowd, and no such matches as we have in these days either. Inside a large wooden bucket in which they fed grain, they carefully laid their kindling. Then turning another bucket over it to keep out of the falling snow, and hugging close over to keep the wind off, they lifted the top bucket a little and one of the Whiting boys struck a precious match. It flickered, blazed a moment against the kindling and was puffed out by a draft of wind. Another match was taken, and it died almost before it flared. Only one match remained to save three men from certain death. Their fingers were so numb they could not feel, and every minute increased their numbness. "Let Orville Try; he is steadier than we", they said. So Orville, keenly sensing his responsibility, took the tiny splinter of wood and struck the spark; it caught, it blazed and the fire lived and grew.
Now they were in the woods and the fuel was plentiful and soon a roaring blaze was swirling upward. The cattle came near, and although their noses and feet were frozen, their feet grew new hoofs and their noses healed of frosted cracks. When the storm broke and light appeared, they found themselves only a few rocks from their home fences.
For a good reason, Orville was not in the Battalion draft. The Whiting boys, Sylvester Hulet, and Amos Cox were. But Orville was very busy manufacturing wagons. It was told of him that he found a linch pin and said, "I'll just make a wagon to fit that pin". He prepared as good and serviceable an outfit as his limited means would allow for the long dreary journey to the mountains. Two home made wagons, without brakes—brakes were not needed on the eastern end of the journey—two yoke of oxen, three yoke of cows, a box of chickens on the back of a wagon, a wife and two children, with bedding and food, was the outfit that started across the plains the last of June 1847, singing the song "In the spring we'll take our journey. All to cross the grassy plains." He travelled in the hundred of Charles C. Rich, known as the Artillery Company. Cox was captain of one of the tens. Oh! the seemingly endless level prairie! The monotony was terribly wearing. When Independence Rock was sighted, and again when Chimney Rock was sighted, it was wonderful relief. Great land marks they were, in that unsettled country. Now they were sure they were approaching the Rocky Mountains, especially the children longed for that goal.
One evening at camping time, 4:00 P.M., a herd of buffalo were sighted about two miles away. The people were very hungry for a piece of fresh beef, so Father and one companion shouldered their guns, snatched their percussion caps and powder horns, and started to "try a hunter's luck." About sunset they got their steak, a generous load of the best cuts from the Buffalo, and started for camp. On and on they went. What they thought was a two mile stretch lengthened and lengthened, and their loads of meat grew heavier and heavier. They began to think they were lost; but the camp fires and stars told them they were going in the right direction. Finally they decided to fire their guns. This they did, and it filled the camp with alarm, least the hunters were in danger. Two or three men rushed away in the darkness to give aid, and they fired their guns to locate the hunters. Several shots brought them together. "Help us with this grub pile", they said. Help was given. They reached the camp at 11:00 o'clock. It must have been six miles or perhaps ten to the herd of buffalo. They were now in the clear air of the up-lands and could see much farther than they had been able to see in the Mississippi valley.
The next morning all in the camp had a feast of fresh meat.
After leaving the Platte River, while travelling along the sweet Water River, the company met General Kearney and his company of Battalion scouts with their illustrious prisoner, the great path-finder Freemont.
(When California was freed from Mexican rule, Freemont and his little band, who had helped to free it, were greatly rejoiced; and in their enthusiasm his followers proclaimed Freemont governor. General Kearney arrived and expected to be governor by right of his generalship. He was very angry and had Freemont arrested and sent to Washington.)
With Freemont's guards were Sylvester Hulet, Elvira's Uncle, and Amos Cox. They had traveled many weary months in an unknown, lonely country; and C.C. Riche's company were also travel weary. To thus meet relatives so unexpectedly was a joy unspeakable to both parties.
