THE UNION FERRY DEPOT,
from which our boat started on its six mile trip across the Bay, is a wonderful structure, and is built on a mud foundation where the Bay has been filled in. It is 659 feet long with a clock tower rising 245 feet. The second story contains a hall the whole length of the building, 48 feet wide and 42 feet high. The building belongs to the State and is used for waiting rooms for some of the great railroads and for the many large ferry boats which cross the Bay to Oakland, Alameda, Berkeley, Sausalito and many other points. The Bay is filled with shipping of every description and from all parts of the world.
