At the Eddy family homestead in Chittenden, Vermont, visitors in 1874 reported seeing figures emerge from a curtained cabinet and hearing musical instruments played in darkness. Henry S. Olcott made the house the centre of a sustained investigation, publishing his observations in newspapers and in People from the Other World in 1875. His measurements, room diagrams and descriptions preserve unusually concrete details of how the séances were arranged.
Olcott became convinced that ordinary impersonation did not explain what he saw. Yet his own account also records poor illumination, disagreements about appearances, restricted views and his inability to impose the test conditions he wanted. The historical case therefore rests on a reporter’s observations and the testimonials he gathered, together with arguments about the adequacy of those observations. Its significance does not require accepting the figures as deceased people.
Two brothers and different kinds of sitting
The preface to Olcott’s 1875 book places its Vermont narrative between late August and the first week of December 1874. In his account of a particular return visit, he says that he reached Chittenden on 17 September and attended a sitting that evening. Those statements describe the period covered by his reporting and one arrival within it; they should not be collapsed into a claim that every described event happened on a single night.
The performances also differed. William Eddy occupied a closet-like cabinet adjoining the raised platform at one end of the upstairs circle-room. Figures described as materialised spirits emerged before the audience. Horatio Eddy’s sittings included hands appearing around a shawl or curtain and instruments sounding while his movements were supposedly controlled. Other circles took place in total darkness. A claim about the controls in one arrangement cannot automatically establish the conditions of the others.
The room Olcott measured
In chapter VII, Olcott describes a room approximately 37 feet 6 inches long and 17 feet wide in an extension to the house. A chimney stood at the far end, with William’s narrow cabinet beside it and a raised platform in front. The book supplies both a section through the platform and a ground plan showing the audience benches, lamp and observer’s position.
His principal architectural question was whether a confederate could reach the cabinet unseen. He reported examining the walls, floor, ceiling and spaces beneath the platform, finding no sliding panels or concealed entrance. He also described looking into the low roof space and taking the undisturbed cobwebs as evidence against recent movement there. These were his inspections of the building, not a modern forensic examination or an independently reproduced survey.
A cabinet window attracted particular suspicion. Olcott says that he obtained permission to cover its outside with fine mosquito netting and to seal it with wax bearing his signet. He inspected it daily for about three weeks and reported that the appearances continued. He also acknowledged a small storm-damaged tear, which he repaired. The detail matters: the source describes a maintained precaution with an interruption, rather than an enclosure that remained untouched throughout the entire investigation.
Olcott printed a certificate dated 26 September 1874 from O. F. Morrill of Chelsea, Massachusetts, whom he identified as an inventor. Morrill said that he had examined the structure with Olcott and found no route for introducing accomplices except the audience-facing door. He rejected jugglery as an explanation while withholding full acceptance of spiritual appearances. The certificate documents a named visitor’s opinion; it does not transform the whole investigation into an institutional verdict.
The first evening and the problem of dim light
For the 17 September sitting, Olcott records twenty-five people assembling during stormy weather. William entered the cabinet shortly after seven, while singing and instrumental music accompanied the proceedings. A high voice from behind the curtain initially struck Olcott as William speaking in falsetto. He later reversed that judgement after believing that he had seen and heard the figure called Mrs Eaton at closer range.
Another recurring figure was called Honto and was presented as an Indigenous woman. Olcott attributed a height of five feet three inches to her, using a painted scale beside the cabinet, and argued that her build and movement differed from William’s. He nevertheless admitted that on his first two viewings the dull light had made him judge her height and bulk much the same as the medium’s.
That admission makes the lighting dispute central. Olcott believed that experience trained the eye and made later estimates reliable. A critic could instead question whether repeated viewing increased familiarity without supplying a better test of identity. Elsewhere in the book Olcott explicitly concedes that facial details were indistinguishable in the available light, while maintaining that stature, costume and broad appearance could be compared. Those are different claims about what an observer could actually see.
The names and identities assigned to the figures remain part of the séance narrative. They are not verified biographies of Indigenous people. Olcott himself expressed doubt that some of the supposed spirit names had an authentic Indigenous origin. This account therefore retains Honto as the name used during the performances, without endorsing the claimed origin or treating the book’s illustrations as photographs of a recovered person.
Horatio’s hands and the spring balances
Olcott also tried to obtain numerical results. In his account of spring-balance experiments, he describes two instruments, each with a fifty-pound capacity. One was fastened for a horizontal pull from the railing; the other was attached to a ring screwed into the floor for a vertical pull. The experiments concerned the hands appearing at Horatio’s circle, rather than the walking figures emerging from William’s cabinet.
On 30 September, with twenty-six spectators reportedly present, Olcott says that a hand protruded and took the balance hook. He read a steady forty-pound pull. On 2 October he reported a vertical pull reaching the instrument’s fifty-pound limit. He associated that second hand with the séance personality George Dix, partly because of what he interpreted as a missing little finger. These are observations and identifications reported by Olcott, not surviving independently calibrated recordings.
A letter he printed from Charles Goodsell supported the first experiment. Goodsell said that he held Horatio’s left hand while Horatio’s right grasped his wrist, and that he nevertheless saw another left hand pull the balance. The evidential burden therefore fell on the reliability of the hand control as well as the scale reading. A measured force would establish neither a disembodied hand nor a spirit’s identity if an ordinary hand could have been freed unnoticed.
A later explanation of the holding test
In The Physical Phenomena of Spiritualism (1907), pages 193–195, Hereward Carrington described the Eddy holding test as deception. He outlined transferring pressure between fingers, or replacing a hand’s pressure with concealed lead or a spring clasp, leaving a real hand free behind the curtain. His discussion supplies a concrete challenge to the assumption that felt pressure guarantees continuous restraint.
Carrington was writing decades later, and the passage is not a report of catching the brothers during Olcott’s particular experiment. His description concerns hand effects, rather than establishing how every full-body figure was produced. His broad statement that Eddy sittings were always illuminated also needs qualification against Olcott’s explicit descriptions of dark circles. The two sources should be compared at the level of the particular test they describe.
What Olcott’s confidence did and did not settle
For a dark circle, Olcott describes sitting in front of Horatio, with another visitor on the medium’s lap, physical contact between the three and instruments sounding around them after the light was extinguished. Such arrangements show the attempts made to detect movement. They also show why a description of restraint could appear convincing while leaving outsiders dependent on touch, sound and the author’s interpretation of what happened out of sight.
In chapter XI, Olcott acknowledged that he had been unable to conduct his experiments under the test conditions he wanted. He still rejected impersonation and accomplices as adequate explanations, and criticised visitors who reached an opposite conclusion after one evening. His prolonged attendance was a real feature of the investigation; duration alone did not resolve the visibility and control problems he described.
The surviving record supports a substantial historical episode of mediumship, observation and disagreement at Chittenden. It preserves specific reported effects, attempted precautions and differing explanations. It does not supply an independently verified materialisation, or a demonstrated reconstruction covering every performance. Reading the arrangements separately makes the case more intelligible than treating either Olcott’s confidence or a later general exposure as a complete verdict.
Sources and related reading
The principal source is Olcott’s People from the Other World, Hartford, 1875, especially the preface and chapters VII, IX, XI, XIV and the spring-balance account on printed pages 253–260. Selected original pages and the cabinet plan were visually checked against extracted text. Carrington’s later critique is used specifically for the holding test. Neither book is presented as a neutral court record or a modern experimental replication.
