GOLDEN GATE, California.—This forms the entrance to San Francisco Bay, which is about seventy miles long and from ten to fifteen wide, and is narrowed into a channel only about one mile wide; here the waters escape in a current as the tide ebbs and flows to and from the ocean. As one approaches from the ocean towards the bay, the south side of the Golden Gate exhibits a shelving point of land which terminates in a long fortification called Fort Point. The portion of the strait between the light house on the north and the fort on the south, is termed "The Golden Gate," or "Chrysopylæ."
