<p>By 1910, the Denny-Renton Clay and Coal Company was one of Renton's most important businesses. Company workers removed the clay from nearby cliffs using high pressure hoses. Other laborers formed and baked the clay into bricks, sewer tile, terra cotta and other building materials. By 1917, the Denny-Renton Clay Company was reportedly the world's largest producer of street paving brick.
This photo, taken in 1908, shows workers using a hose to extract clay from a hillside.</p>
