The San Joaquin and Sacramento Rivers, having united, flow westward into Suisun Bay, thence by a strait to the circular and expansive San Pablo Bay, which in turn empties into San Francisco Bay. On the strait connecting Suisun and San Pablo Bays is Benicia, where lived the famous pugilist John C. Heenan, the "Benicia Boy," and the immense forge-hammer he wielded is on exhibition there. At the head of San Pablo Bay is Napa, or Mare Island, the location of the Navy Yard. Upon the mainland opposite is Vallejo, whence a railway runs up the fertile Napa Valley, through orchards and vineyards and among mineral springs, to Calistoga. Near here is the strange Petrified Forest, where there are scattered upon a tract of four square miles the remains of a hundred petrified trees. The Bay of San Francisco is a magnificent inland sea, fifty miles long and ten miles wide, connected with the Pacific Ocean by the strait of the Golden Gate, five miles long and a mile wide. The bay is separated from the ocean by a long peninsula, having the city of San Francisco on the inside of its northern extremity. Over opposite, on the eastern shore of the bay, is Oakland, the terminal of the Southern Pacific Railway routes from the East, a city of fifty thousand people, named from the numerous live-oaks growing in its gardens and along the streets. It has extensive manufactures and a magnificent view over the expansive bay and city of San Francisco and the distant Golden Gate, where the enclosing rocky shores can be seen rising boldly, the northern side to two thousand feet height. In the Oakland suburbs is Berkeley, where are some of the College buildings of the University of California, founded in 1868 and having twenty-three hundred students, many of them women. The attractive grounds cover two hundred and fifty acres, and the endowments exceed $8,000,000. South of Oakland is the pleasant suburban town of Alameda. On the western shore of the bay, south of San Francisco, is Menlo Park, a favorite place of rural residence for the wealthy San Francisco people, having many handsome villas and estates with noble trees. Here is Palo Alto or the "tall tree," taking its name from a fine redwood tree near the railway, an estate of over eight thousand acres, which is the location of the noted Leland Stanford, Jr., University. This is the greatest educational endowment in America, having a fund of over $30,000,000, the gift of Senator and Mrs. Leland Stanford in memory of their only son. The University has twelve hundred students, many being women. The buildings, which in a manner reproduce the architecture of the ancient Spanish Missions, are of buff sandstone, surmounted by red-tiled roofs, picturesquely contrasting with the oaks and eucalyptus trees which are so numerous and the many tropical plants that have been brought there. The Palo Alto estate is one of the great California stock-farms.
