curve.
Once upon a time—about the year 1870—occurred an unusual sporting event. John Hampden, who was noted for his piety and his bad language, whose avowed purpose was to support the principles of this earth’s earliest geodesist, offered to bet five hundred pounds that he could prove the flatness of this earth. Somewhere in England is the Bedford Canal, and along a part of it is a straight, unimpeded view, six miles in length. Orthodox doctrine—or the doctrine of the newer orthodoxy, because John Hampden considered that he was orthodox—is that the earth’s curvature is expressible in the formula of eight inches for the first mile, and then the square of the distance times eight inches. For two miles, then, the square of two, or four, times eight. An object six miles away should be depressed 288 inches, or, allowing for refraction, according to Proctor (Old and New Astronomy) 216 inches. Hampden said that an object six miles away, upon this part of the Bedford Canal, was not depressed as it “should” be. Dr. Alfred Russell Wallace took up the bet. Mr. Walsh, Editor of the Field, was the stakeholder. A procession went to the Bedford Canal. Objects were looked at through telescopes, or looked for, and the decision was that Hampden had lost. There was rejoicing in the fold of the chosen, though Hampden, in one of his most furious bombardments of verses from the Bible, charged conspiracy and malfeasance and confiscation, and what else I don’t know, piously and intemperately declaring that he had been defrauded.
In the English Mechanic, 80-40, someone writes to find out about the “Bedford Canal Experiment.” We learn that the experiment had been made again. The correspondent writes that, if there were basis to the rumors that he had heard, there must be something wrong with established doctrine. Upon page 138, Lady Blount answers—that, upon May 11, 1904, she had gone to the Bedford Canal, accompanied by Mr. E. Clifton, a well-known photographer, who was himself uninfluenced by her motives, which were the familiar ones of attempting to restore the old gentleman who first took up the study of geodesy. However, she seethes with neither piety nor profanity. She says that, with his telescopic camera, Mr. Clifton had photographed a sheet, six miles away, though by conventional theory the sheet should have been invisible. In a later number of the English Mechanic, a reproduction of this photograph is published. According to this evidence this earth is flat, or is a sphere enormously greater than is generally supposed. But at the 1901 meeting of the British Association for the Advancement of Science, Mr. H. Yule Oldham read a paper upon his investigations at the Bedford Canal. He, too, showed photographs. In his photographs, everything that should have been invisible was invisible.
I accept that anybody who is convinced that still are there relics upon Mt. Ararat, has only to climb Mt. Ararat, and he must find something that can be said to be part of Noah’s Ark, petrified perhaps. If someone else should be convinced that a mistake has been made, and that the mountain is really Pike’s Peak, he has only to climb Pike’s Peak and prove that the most virtuous of all lands was once the Holy Land. The meaning that I read in the whole subject is that, in this Dark Age that we’re living in, not even such rudimentary matters as the shape of this earth have ever been investigated except now and then to support somebody’s theory, because astronomers have instinctively preferred the remote and the not so easily understandable and the safe from external inquiry. In Earth Features and Their Meaning, Prof. Hobbs says that this earth is top-shaped, quite as the sloping extremities of Africa and South America suggest. According to Prof. Hobbs, observations upon the pendulum suggest that this earth is shaped like a top. Some years ago, Dr. Gregory read a paper at a meeting of the Royal Geographical Society, giving data to
