- Judge Strong, who was one of the territorial judges, always came to the post on his trips to hold court. He lived on the Columbia. Starling was the Indian agent. Moses was collector of the post, and lived at Olympia. Goldsborough, Mason, Simmons, in fact, all of the first pioneers were seen at the post frequently during the few months of my tour of duty. Steilacoom was the place where the vessels landed, and it was called a city, although there were only a few houses. Dr. Webber had a store and dealt in lumber. Mr. John M. Chapman had taken the best of the ground for the town and Lafayette Balch had taken a claim adjoining to the north, and was in partnership, too, with Webber.

The Columbia River (Upper Chinook: Wimahl or Wimal; Sahaptin: Nch’i-Wàna or Nchi wana; Sinixt dialect swah’netk’qhu) is the largest river in the Pacific Northwest region of North America. The river forms in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is 1,243 miles (2,000 kilometers) long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven states of the United States and one Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world.
