The construction of a rubble masonry wall on top of bedrock in Section 4, September 1894. A single leg derrick is used to lift and place each masonry stone. The masonry courses were set back at vertical intervals to emulate the steps created by the channeling machines in solid bedrock. (MWRD photo, disc 4126, image 88)
