The remarkable manner in which this prophecy has been fulfilled the most casual observer will readily admit; for Spiritualism—even as a religious power—has far outstripped any other form of religion in the world in the rapidity of its growth, having reached every civilized nation and permeated every other form of belief in less than half a century.

The Fox Sisters were still called the "Rochester Knockers," the "Fox Girls," the "Rappers," and other epithets, equally foolish and obnoxious to their interests and feelings. Catherine Fox, the youngest girl, had been removed to the house of Mr. W. E. Capron, of Auburn. Mrs. Fish, though generally present when phenomena were transpiring, was not in its earliest phases conscious of being a medium. Margaretta, the other sister, was then in reality the only one through whom the manifestations appeared to proceed, when in November, 1848, the spirits, who had long been urging them to permit public investigations to be made through her mediumship, informed them by raps that "they could not always strive with them," and since they were constantly disobedient to the spirits' requests, and obviously opposed to their presence, they should leave them, and in all probability withdraw for another generation, or seek through other sources for the fulfilment of the high and holy purposes for which this spiritual outpouring had been designed. To these appeals the family were inflexible. They constantly prayed that the cup of this great bitterness "might pass from them." They did not wish to be "mediums," and abhorred the notoriety, scandal, and persecution which their fatal gift had brought them, and when warned that the spirits would leave them, they protested their delight at the announcement, and expressed their earnest desire that it might be fulfilled.

There were present at a circle, when communications of this character were made, several influential persons of the city, who had become greatly interested in the manifestations and were warm friends of the family. They could not, however, realise that the threat here implied would actually be fulfilled until the spirits, by rappings, spelled out several messages of a particularly affectionate and valedictory character. The scene became, says an eye-witness, solemn and impressive. The spirits announced that in twenty minutes they would depart, and exactly as that time expired they spelled out, "We will now bid you all farewell;" when the raps entirely ceased.

The family expressed themselves "glad to get rid of them;" the friends present vainly tried to obtain, by solicitations, made, as it would seem, to empty air, some demonstration that this beneficent and wonderful visitation had not indeed wholly ceased. All was useless. A mournful silence filled the apartment which had but a few minutes before been tenanted with angels, sounding out their messages of undying affection, tender counsel, wise instruction, and prescient warning. The spirits indeed were gone; and as one by one the depressed party separated and passed out into the silent moonlit streets of Rochester, all and each of them felt as if some great light had suddenly gone out, and life was changed to them. There was a mighty blank in space and a shadow everywhere, but spirit light came no more to illuminate the thick darkness.

A fortnight passed away, during which the former investigators called constantly on the Fox family to enquire if their spirit friends had returned. For the first few days a stoical negative was their only reply; after this, they began more and more fully to recognise the loss they had sustained. The wise counsellors were gone; the sources of strange strength and superhuman consolation were cut off. The tender, loving, wonderful presence no more flitted around their steps, cheered their meals, encouraged them in their human weakness, or guided them in their blindness. And these most wonderful and providential beings their own waywardness had driven from them. At last, then, they met their enquiring friends with showers of tears, choking sobs, and expressions of the bitterest self-reproach and regret.

On the twelfth day of this great heart-dearth, Mr. W. E. Capron, being in Rochester on business, called at the house of Mrs. Fish, with Mr. George Willets, a member of the Society of Friends, and one of their earliest spiritual investigators. On receiving the usual sorrowful reply that "the spirits had left them," Mr. Capron said: "Perhaps they will rap for us if not for you." They then entered the hall and put the usual question if the spirits would rap for them, in answer to which, and to the unspeakable delight of all present, they were greeted with a perfect shower of the much-lamented sounds.

Once more the spirits urged them to make the manifestations public. Again they reiterated the charge with solemn earnestness, and despite of the mediums' continued aversion to the task imposed upon them, the fear of a fresh and final bereavement of the inestimable boon of spirit communion prevented their continued resistance to the course proposed.

When the persons who were called upon to aid the mediums and take somewhat prominent parts in the work urged the awkwardness of the positions assigned them, the spirits only replied, "Your triumph will be so much the greater." There is no doubt that the severe warning they had just received, and the fear of its repetition, acted upon the whole party with more force than any argument that could have been used to induce their submission.

At the injunctions of the spirits a public investigation into the possibility of communion between the world of spirits and the earth they once inhabited was carried out. Magistrates, editors, and professional men were the judges, and enlightened American citizens the jury. The aim of wide-spread publicity was attained. Thousands heard and wondered at, and finally believed in spiritual communion who would never have dreamed of the subject but for the persecution and slander that was publicly directed against the "Rochester Knockers."

The records of these persecutions and slanders abound with disgraceful and painful incidents which, whilst being discreditable to the persons responsible for their propagation redound with full credit to the honour and integrity of the mediums selected by the Spirit world to be the forerunners of a new dispensation.
