dc.description.abstractA jumbo is a mobile drill carriage or scaffold on which several drills could be mounted. This image may depict the construction of tunnels for New York City's water supply from the Catskill watershed. In 1905 the New York State legislature passed an act allowing the City to acquire lands and build water control structures in the Catskills for its water supply, including the East Delaware Tunnel, West Delaware Tunnel and the Rondout Tunnel (Delaware Aqueduct).
