There was a certain shipmaster on board who had left his vessel in Rio Janeiro, with directions to the mate to bring her to San Francisco, by way of Cape Horn. The oracle was consulted as to the position of the ship at that particular time. Without a moment's hesitation, the latitude and longitude of the vessel were given, placing her somewhere off Valparaiso (Chili). "That's just where _I_ put her!" cried the master with an ejaculation of unfeigned surprise. On reaching San Francisco shortly after, the vessel was discovered quietly tied up at one of the wharves. I found too, on landing, that the prophecy, "You will find important letters awaiting you from home," was not fulfilled, neither in my case nor in that of the other "worker." Now in the case of putting down the position of the merchant vessel, the "worker" who was operating with me at the time did not know how to plot the position of a ship at sea, after the manner of seamen; and although the method of stating a ship's position was perfectly familiar to me, yet I _anticipated_ that the answer in regard to her would have been given in general and indefinite terms. What was my astonishment, then, to find distinctly written out, "Latitude 35 deg. 30 min. S.; longitude 98 deg. 40 min. W." True this position was about four thousand miles out of the way, but where did the answer, such as it was, come from? Continued experiments proved that in every instance where Planchette attempted to foretell an event, it failed ignominiously; and while it replied to questions with the utmost effrontery, it was rarely correct, unless indeed, as it shrewdly said itself, "the worker was reliable as an informant." Many months after these experiments, I found myself on the shores of southern France. Here my associations were entirely different from those I had known in the far-off Pacific, and, desirous of ascertaining how Planchette would comport itself under the change of conditions, I essayed further trials. It will be sufficient to give one example of the answers given: "What should one do," it was asked, "when life becomes unbearable?" The answer was contained in one word, but written in such a scrawl as to be illegible. The question was repeated, when the same word apparently was written in reply, but still illegible. The question was put a third time, when Planchette, with great energy, wrote in bold characters, and distinct, the word PRAY. On comparing this with the former answers, they were found to be the same. The question, however, is not as to the degree of faith to be placed in the words of Planchette, but why should it write at all? In attempting to answer this question, I shall confine myself mainly to the field of daily experience, and draw illustrations from such works only as are familiar to the great majority of readers.
