At the loading switch two cars are shifted at atime by means of the hand winch and cable and are keptspotted so that material can be shoveled directly into the4-yd. hopper car without rehandling. By the use of theelevated inclined track sand and stone were piled highclose to the mixer, requiring far less hand wheeling thanwould have been possible with material delivered by teamsand wagons. The entire operation of this plant is highlyefficient and it demonstrates what can be accomplishedwith light, portable, inexpensive equipment in difficult. Inclined Track and Mixing Plant.

The conditions confronting the contractor there-fore was a large area of loose sand over which it wouldhave been difficult to haul material with teams andwagons. The structures comprised a main building 120x184 ft., apower plant 60x80 ft., a saw-filing house 18x40 ft., and anoffice 26x32 ft. Owing to the loose sand fill it was neces-sary to construct comparatively deep side walls andfoundation piers, requiring a large quantity of soft nature of the ground also made the most prac-tical design of plant one in which all concrete was mixedat a single point from which it was wheeled to the mixing plant was therefore located close to the endsof the main building and power plant and about 160 the railroad switch.
