The Long-Bell Lumber Company, led by Robert A. Long, made the decision in 1918 to buy a great expanse of timberland in Cowlitz County. A total of 14,000 workers were needed to run the two large mills as well as lumber camps that were planned. The number of workers needed was more than a lumber town, or the nearest town, could provide. Long planned and built a complete city in 1921 that could support a population of up to 50,000 and provide labor for the mills as well as attracting other industries. Several buildings in the city were built from Long's private funds.
