June 1, 1906. Called a traveler because it is on rails and travels along with the work, this piece of equipment mixes concrete for placement in the forms used for building the east and west walls. The ingredients for each concrete batch are delivered by rail to the traveler, and, after mixing, the concrete is placed through the long hanging tubes. As the wall rises in height, shorter tubes will be used. (MWRD photo 3440)
