 Davis and Henry Brooks opened a brickyard on South Monroe between what would later be known as Cannon Hill Park and Cannon's Addition.The site was rich in clay deposits, and the brickyard was later developed into the Washington Brick, Lime & Sewer Pipe Company.By 1900, Cannon's Addition began to experience increased growth and evolved into a middle class residential neighborhood; over the next fifteen years Spokane grew from a city of 30,000 to a population of 100,000.
