Excerpt from the St. Helens Sentinel Mist February 28, 1936 promoting Scappoose:
SCAPPOOSE HOME OF MANY LARGE SCALE OPERATIONS AND IS ALSO HOME SITE
It is considered a sportsman's paradise with boating attractions and unlimited salmon trolling in season.
It is the home of the fertile Delta lands comprising 5700 acres of diked farms. Beet, turnip, cabbage, and other valuable seeds are grown in quantity. Peas, beans, cucumber, potatoes, tomatoes, cabbage, and sweet corn yield bountifully.
When the plants are in bloom, the Peterson & Dering rose farm is one of the northwest's admired beauty spots.
Ideal living conditions and low overhead are assets of the locality. Fine schools, parks and streets, with electricity and water available add to it as a home place.
Two of the best ventilated potato cellars in the northwest, with a capacity of 250 cars of potatoes, the California Conserving Company with 15 acres for expansion, Peterson & Dering who are wholesale growers of roses and will double their plant's capacity this season, the West Coast Shoe factory which is famous through northwestern logging camps for high grade, hand made logging shoes. Blehm Broom factory which is a maker of quality brooms and is gaining prestige rapidly, the Haffner Cereal plant which is continually developing new breakfast foods and sending them to all parts of the northwest, E. E. Kingsley Lumber company which was compelled to increase its capacity this season to meet the demands for building material -- all of these are reasons for the prosperity of Scappoose. Also to be included is the Komning Lumber company.
Scappoose grade school has seven acres of playground and is one of the best equiped in the county. Scappoose high school cost $50,000 and is recognized for efficiency. It has an ideal football and track field.
