Proctor states that it "can be tried." He says, however, that the distance involved in the experiment "should be three or four miles." Now, Mr. Wallace took up six miles in his experiment, and was unable to prove that there is any "curvature," though he claimed the money and got it; surely it would be "amusing" for anyone to expect to be able to show the "curvature of the earth" in three or four miles, as Mr. Proctor suggests! Nay, it is ridiculous. But "the greatest astronomer of the age" says the thing can be done! And he gives a diagram: "Showing how the roundness of the Earth can be proved by means of three boats on a large sheet of water." (Three or four miles.) But, though the accepted astronomical theories be scattered to the winds, we charge Mr. Proctor either that he has never made the experiment with the three boats, or, that, if he has, the experiment did NOT prove what he says it will. Accepted theories, indeed! Are they to be bolstered up with absurdity and falsehood? Why, if it were possible to show the two ends of a four-mile stretch of water to be on a level, with the centre portion of that water bulged up, the surface of the Earth would be a series of four-mile curves! But Mr. Proctor says: "We can set three boats in a line on the water, as at A, B, and C, (Fig. 7). Then, if equal masts are placed in these boats, and we place a telescope, as shown, so that when we look through it we see the tops of the masts of A and C, we find the top of the mast B is above the line of sight." Now, here is the point: Mr. Proctor either knows or he ought to know that we shall NOT find anything of the sort! If he has ever tried the experiment, he knows that the three masts will range in a straight line, just as common sense tells us they will. If he has not tried the experiment, he should have tried it, or have paid attention to the details of experiments by those who have tried similar ones a score of times and again. Mr. Proctor may take either horn of the dilemma he pleases: he is just as wrong as a man can be, either way. He mentions no names, but he says: "A person had written a book, in which he said that he had tried such an experiment as the above, and had found that the surface of the water was not curved." That person was "Parallax," the founder of the Zetetic Philosophy. He continues: "Another person seems to have believed the first, and became so certain that the Earth is flat as to wager a large sum of money that if three boats were placed as in Fig. 7, the middle one would not be above the line joining the two others." That person was John Hampden. And, says Mr. Proctor, "Unfortunately for him, some one who had more sense agreed to take his wager, and, of course, won his money." Now, the "some one who had more sense" was Mr. Wallace. And, says Proctor, in continuation: "He [Hampden?] was rather angry; and it is a strange thing that he was not angry with himself for being so foolish, or with the person
