Round trip special Exposition railway tickets at greatly reduced rates are available from all points to San Francisco, Los Angeles or San Diego as the destination. The price of tickets from points east of the Rocky Mountains is the same whether the destination be San Francisco, Los Angeles or San Diego. The trip going and returning may be by the same route or by different routes, but the routes described on the tickets must be followed. Tickets from Chicago and farther east are valid going or returning via New Orleans. Tickets via Portland, Seattle, etc., involve a supplementary charge, concerning which the local railway representatives should be consulted. The baggage of those who intend to stay in Berkeley should be checked directly to Berkeley, California (by either the Southern Pacific or Santa Fe routes) instead of to San Francisco. All round trip tickets require validation for the return trip.
Railway rates have been greatly reduced, the cost of a round trip being $62.50 from Chicago and $94.30 from New York.
Special lines of steamers advertise passage between the Atlantic and Pacific Coast by way of the Panama Canal at rates varying between $135 and $198 (one way).
Stop-overs for side trips can be arranged either going or returning. Round trip rate from San Francisco to Hawaiian Islands and return by either of several lines of steamers from $110 up. Yellowstone National Park is reached from Livingston on the Northern Pacific (to Gardner and return $3.20). A six-day trip in the park from Gardner costs $40 and another of 534 days $53.50. Yellowstone Park may also be reached from Ogden on the Union Pacific by a branch to Yellowstone (round trip $9.25). From here a five-day trip in the park costs $35 and a six-day trip $40.
The Yosemite National Park is reached by Southern Pacific or Santa Fe lines, stopping at Merced, Cal. Round trip from Merced to Valley $18.50. Both hotels and comfortable camps may be found at the camp. Several groves of Big Trees may be visited from the Valley. One grove very much visited is only six miles from Santa Cruz (on the Southern Pacific).
Alaska may be visited by steamer trip from Seattle or Vancouver. Round trip from Seattle $66 and up. From Prince Rupert (on Grank Trunk) a trip to Alaska may be made at an additional expense of about $30.
Attention may be called to two publications which will add to the scientific interest of the trip. The Pacific Coast Committee of the American Association has compiled a guide book entitled "Nature and Science on the Pacific Coast," which contains a large number of articles by leading men of science. The United States Geological Survey has prepared four guide books covering railway routes west of the Mississippi. These books, which contain full descriptions and excellent maps, may be obtained by sending one dollar for each to the Superintendent of Documents, Washington, D. C.
