SANDHOGS

A 20th Century-Fox production available only to schools. "A factual story of the various operations incident to the building of an underground tunnel. Various sequences show workers entering the tunnel by elevator; the operation of air-pressure gauges; exit from the air chamber into the tunnel itself, workers using rock drills, scoops, and dynamite for the blasting." "The work of the men engaged in this precarious operation is idealized as they are shown removing mud, damming off and pumping out water, erecting girders, welding, and 'holing through.' Thus is a vehicle presentation of the labor that goes into the construction of a modern convenience used by millions." "Recommended for use in junior and senior high schools for social studies groups studying transportation and industries. Might be useful also for vocational guidance groups discussing essential labor and motivation." Advisory committee
