Jack Robinson was a man in olden days who became well known because of the shortness of his visits when he came to call on his friends, according to Grose, who has looked up the subject very carefully. When the servants at a home where Jack Robinson called went to announce his coming to the host and his assembled guests, it was said that they hardly had time to repeat his name out loud before he would take his departure again. Another man, Halliwell, who has also investigated the development of the expression, thinks that it was derived from the description of a character in an old play, “Jack, Robes on.” It is also interesting to learn that the sandwiches which we all enjoy so much at picnics are so called because of the fact that an English nobleman, the Earl of Sandwich, always used to eat his meat between two pieces of bread. What is an Aerial Railway Like? Wonderful ingenuity has been shown in contriving a means to enable people to ascend the Wetterhorn Mountain in Switzerland. The sides of the mountain are so irregular and rough in their formation that it was found impossible to build even the incline type of railway, such as is usually resorted to where the ascent to a mountain is particularly steep. So the engineers who studied the problem finally contrived two huge sets of cables, securely fastened at the top, and fixed to a landing place a short distance from the base of the mountain. Cars, holding twenty passengers each, are carried up and down these cables, one car balancing the other, by means of a cable attached to each, which passes around a drum at the top. [Illustration: THE WETTERHORN AERIAL RAILWAY _Reproduced by permission of The Philadelphia Museums._] There is probably no railway in all Europe upon which travel affords more wonderful scenery than this trip, suspended in the air, up the side of the Wetterhorn Mountain, the three peaks of which are all considerably more than two and a quarter miles high. Why are They Called “Newspapers”? Although something like an official newspaper or government gazette existed in ancient Rome, and Venice in the middle of the sixteenth century also had official news sheets, the first regular newspaper was published at Frankfort in 1615. Seven years later the first regular newspaper appeared in England. It was customary to print the points of the compass at the top of the early single-sheet papers, to indicate that occurrences from all four parts of the world were recorded. Before very long, the publisher of one of the most progressive papers rearranged the letters symbolic of the points of the compass, into a straight line, and printed the word NEWS, and in a very short time practically every newspaper publisher decided to adopt the idea.
