There are a few, however, who have been so pre-eminent and so involved in public polemics that no history of the movement can disregard them, even if their careers have not been in all ways above suspicion. We shall deal in this chapter with the histories of Slade and Monck, both of whom played a prominent part in their days.
Henry Slade, the celebrated slate-writing medium, had been before the public in America for fifteen years before he arrived in London on July 13, 1876. Colonel H. S. Olcott, a former president of the Theosophical Society, states that he and Madame Blavatsky were responsible for Slade's visit to England. It appears that the Grand Duke Constantine of Russia, desiring to make a scientific investigation of Spiritualism, a committee of professors of the Imperial University of St. Petersburg requested Colonel Olcott and Madame Blavatsky to select out of the best American mediums one whom they could recommend for tests.
They chose Slade, after submitting him to exacting tests for several weeks before a committee of sceptics, who in their report certified that "messages were written inside double slates, sometimes tied and sealed together, while they either lay upon the table in full view of all, or were laid upon the heads of members of the committee, or held flat against the under surface of the table-top, or held in a committeeman's hand without the medium touching it." It was en route to Russia that Slade came to England.
A representative of the London World, who had a sitting with Slade soon after his arrival, thus describes him: "A highly-wrought, nervous temperament, a dreamy, mystical face, regular features, eyes luminous with expression, a rather sad smile, and a certain melancholy grace of manner, were the impressions conveyed by the tall, lithe figure introduced to me as Dr. Slade. He is the sort of man you would pick out of a roomful as an enthusiast." The Seybert Commission Report says, "he is probably six feet in height, with a figure of unusual symmetry," and that "his face would attract notice anywhere for its uncommon beauty," and sums him up as "a noteworthy man in every respect."
Directly after his arrival in London Slade began to give sittings at his lodgings in 8 Upper Bedford Place, Russell Square, and his success was immediate and pronounced. Not only was writing obtained of an evidential nature, under test conditions, with the sitter's own slates, but the levitation of objects and materialized hands were observed in strong sunlight.
The editor of THE SPIRITUAL MAGAZINE, the soberest and most high-class of the Spiritualist periodicals of the time, wrote: "We have no hesitation in saying that Dr. Slade is the most remarkable medium of modern times."
Mr. J. Enmore Jones, a well-known psychic researcher of that day, who afterwards edited THE SPIRITUAL MAGAZINE, said that Slade was taking the place vacated by D. D. Home. His account of his first sitting indicates the business-like method of procedure: "In Mr. Home's case, he refused to take fees, and as a rule the sittings were in the evening in the quiet of domestic life; but in Dr. Slade's case it was any time during the day, in one of the rooms he occupies at a boarding-house. The fee of twenty shillings is charged, and he prefers that only one person be present in the large room he uses. No time is lost; as soon as the visitor sits down the incidents commence, are continued, and in, say, fifteen minutes are ended." Stainton Moses, who was afterwards the first president of the London Spiritualist Alliance, conveys the same idea with regard to Slade. He wrote: "In his presence phenomena occur with a regularity and precision, with an absence of regard for 'conditions,' and with a facility for observation which satisfy my desires entirely. It is impossible to conceive circumstances more favourable to minute investigation than those under which I witnessed the phenomena which occur in his presence with such startling rapidityÉ. There was no hesitation, no tentative experiments.
