Beginning of a skyscraper /
The scene is an excavation site in New York City. A large group of workmen with picks and shovels are digging. Carts drawn by pairs of horses can be seen emerging from the smoke in the background.
From a contemporary American Mutoscope and Biograph Company catalog: Starting a Skyscraper--New York--26 feet. Taken in the immense excavation for the foundation of the new Macy Building at the corner of Broadway and 34th Street, New York. An excellent study of modern American push and enterprise.
