In the morning to tumble out of your hotel into that same strange town in the clarity of early sunshine, to have this great street or that or that--Market or Geary or Powell--stretching forth as if longing to invite your explorations--here again is the fascination of travel. The big trolley cars come rolling up Market street in quick succession, and for an instant their appeal is strong. But over there is a car of another sort, running on narrow-gauge tracks and with the roar of an endless cable ever at work beneath the pavement. The little cars upon those narrow tracks interest you. They are as gaily colored and as bravely striped as any circus wagon of boyhood days, and when you pay your fare you can take your choice--between the interior of a stuffy little cabin amidships or open seats at either end arranged after the time-honored fashion of Irish jaunting cars. San Franciscans do not hesitate. They range themselves along the open seats of the dinky cars and look proud as toads as the cars go clanking up the awful hills. The San Francisco cable car is in a transportation class by itself. It clings tenaciously to early traditions. For in San Francisco the cable railroad was born--and in San Francisco the cable railroad still remains. One Andrew S. Halladie was its inventor--somewhere early in the "seventies." Up Clay street hill, and to know and appreciate the slope of Clay street hill one must have seen it once at least, Halladie's first car struggled, while its passengers held their breaths just as first-comers to San Francisco still hold their breaths as they ride up and down the fearful hills. The telegraph told to the whole land how a street railroad was running on a rope out in that little-known land of marvels--California. But the telegraph could not tell what the railroad on a rope meant to San Francisco--San Francisco encompassed and held in by her high sand hills. The Clay street cable road had conquered one of the meanest of these hills and they began to plan other roads of a similar sort. Like a blossoming and growing vine the city spread, almost overnight. Sand-dunes became building-lots of high value and a new bonanza era was come to San Francisco. And, with the traditional generosity of the coast, she gave her transportation idea to other cities. In a little while St. Louis, Chicago, Washington and New York were banishing the horse cars from their busiest streets. A new era in city transit was begun. A few years later the broomstick trolley--cheaper and in many respects far more efficient--displaced the cable-cars in many of these cities. But San Francisco up to the present time has stuck loyally to her old-time hill conquerors. And the nervous lever-clutch of the gripman as he "gets the rope" is as distinctive of her as are the fantasies of her marvelous wooden architecture.
