The Giant's Causeway, of which much has been written, for it is one of the wonders of the world, lies on the north coast of Ireland, about two hours by rail from Belfast, and there are several trains daily to the nearest town, called Portrush. There is an excellent hotel there, owned by the railway company, which ranks as one of the best in Ireland, and several other smaller hotels, inns, and boarding-houses innumerable for the accommodation of the crowds of people who go there every year as "trippers" and to spend their holidays. The Giant's Causeway, about five miles from Portrush, is reached by an electric railroad, which, I am told, was the first ever successfully operated in all the world. It was built in 1883, designed by the late Sir William Siemens, the celebrated electrician, and operated with power generated by the water of the Bush River. It was originally on the third-rail system, but was changed into an ordinary overhead trolley seven or eight years ago. The first trolley railroad was built in Richmond, Va., three years later than this. The most interesting object at Portrush is an ancient but well preserved Irishman of the type you see in pictures and formerly on the stage, who stands at the street corner, where the railway tracks take a curve, with a big dinner bell and rings it with almost superhuman energy whenever the cars approach from either direction. This occupation engages him from some unknown hour in the morning until some unknown hour in the night, and if he ever eats or sleeps or rests that fact is not easily ascertained by a stranger. There are no bells on the cars, no alarm can be given for some reason, but nobody ever complained that he was not warned of danger at the crossing by the bell ringer, who seems to have a profound sense of his responsibilities. It is a delightful ride along rocky cliffs that have been worn into fantastic forms by the incessant pounding of the ocean, and, although many people express their disappointment at the Giant's Causeway, it is well worth a visit because it is unique in geology. A stream of lava, at the most twenty-six hundred feet wide and about fifteen miles long, was arrested by some means upon the extreme north coast of Ireland, and in cooling took the form of detached columns from six to thirty feet long and from eight to twenty-four inches in diameter. There are more than forty thousand of these columns in three parallel terraces, standing upright and presenting a smooth surface, but they are all separate and no two of them are of the same size or shape. There is said to be only one triangle, only one nonagon, and only one of diamond shape in all the forty thousand. Most of them are pentagons and hexagons and octagons.
