Parrish and the others arrived in Oregon in May 1840. In California the vessel was sold in order to purchase cattle to be
driven overland to the Willamette Valley. On February 1, 1842, Parrish was selected as a trustee to the new
Oregon Institute, a school established to teach the children of the missionaries that later became
Willamette University. Also in 1842, Parrish moved to the
Clatsop Plains and took over the
Clatsop Mission from
Joseph H. Frost. In 1844, when the Methodist Mission was dissolved by George Gary, Parrish purchased the Clatsop Plains mission. From 1849 until 1854 he worked as an Indian agent in the now
Oregon Territory. As a rancher he was the first breeder in Oregon of pure-breed sheep, and had brought the first white clover seed to Oregon when he migrated aboard the Lausanne. ==Later life==
