In 1835 Parker and his new recruit, Marcus Whitman, joined the fur-traders’ caravan and headed westward. Not until cholera had broken out and Dr. Whitman’s medical skill had prevented disaster in the caravan did the unholy traders appreciate having the missionaries in their group. On August 12 the party reached the fur-trading rendezvous, which was held that year near the junction of Horse Creek and the Green River in Wyoming. There, once again Whitman was able to display his medical skill. He successfully removed a 3-inch iron arrowhead from the back of the famous mountain man, Jim Bridger, under the watchful eyes of traders, mountain men, and Indians. This exhibition of competence was not lost on the Nez Percé and Flathead. Parker and Whitman talked to them and found that they were indeed anxious to have missions. To get the missions established by the next year, Whitman decided to return East and organize volunteers for the new field. Parker was to continue on to Oregon, explore for mission locations, and meet Whitman’s party when it reached the rendezvous the next summer. Parker, traveling with the Nez Percé, reached their homeland on the Clearwater River in present Idaho late in September. Thence he went down the Columbia River to Fort Vancouver, where he spent most of the winter with the Hudson’s Bay Company traders. During the winter and the next spring, he made several trips of exploration in the country between the Clearwater and the Willamette. In the spring of 1836, he learned that the Nez Percé were returning to the rendezvous by a northerly, rugged route. Parker, feeling his years at last, decided to return to the United States by sea. Before the Indians’ departure, he wrote letters for them to carry to the rendezvous. Although Whitman received these letters, it is doubtful if they contained any information of value to the 1836 American Board party. While Parker was at Fort Vancouver, Marcus Whitman, back in New York, had been busy gathering men and money in order to establish the missions in the Oregon country. [Illustration: Marcus Whitman’s certificate appointed him “an assistant missionary to Indian tribes West of the State of Missouri.” It was also necessary for the missionaries to get permission from the Secretary of War to visit the Indian lands of western United States.] _“We Want You for Oregon”_ On his return trip from the rendezvous in 1835, Whitman wrote to Rev. David Greene, one of the secretaries of the American Board, about the need for recruits for Oregon. Greene in his reply told Whitman about two missionaries who had volunteered for the West; he also cautioned Whitman against taking a bride into the wilderness.
