Frederick Spencer Oliver said that an occult teacher called Phylos supplied the material for A Dweller on Two Planets. His account places the beginning of the work at Yreka, California, in 1883–1884 and its completion in Santa Barbara County in 1886. The surviving published preface is a detailed personal claim about inspiration and dictation. It does not independently establish the existence of its claimed outside author.

The published object and the claimed experience
The title page of the 1905 first edition attributes the book to “Phylos the Thibetan” and names Baumgardt Publishing Company of Los Angeles. A Library of Congress copy, digitised by Internet Archive, preserves that published object. It is direct evidence of what readers were being offered in 1905. The dates of the experiences described inside it must be considered separately.
Oliver’s own preface calls him an amanuensis: a person writing for someone else. Born in Washington, DC, in 1866, he said that his parents brought him to California two years later. He presented his limited education as part of the puzzle, arguing that the scope of the book exceeded his ordinary attainments. That is his self-description, not a comparison of the manuscript against independently established records of his reading or education.
Yreka, a family circle and a private teacher
At one point Oliver says writing commenced in 1884; elsewhere he gives 1883–1884. His narrative describes an initial period of mental conversations with Phylos, followed by concern from his father about his withdrawal from ordinary life. After Oliver explained himself, his parents wanted to hear the teacher too. According to Oliver, Phylos would not speak directly to them, but allowed Oliver to repeat what he heard.
He names a home circle consisting initially of his parents, W. S. Mallory and himself, with Mrs S. M. Pritchard and Mrs Julia P. Churchill attending later. He explicitly places this beginning in Yreka, Siskiyou County. These names make the account more specific, but the preface remains Oliver’s report of their involvement. Separate statements from those participants have not been examined for this case. Their inclusion should not be presented as several independent confirmations of the teacher.
Oliver also says the book was begun within sight of Mount Shasta and almost finished there, before completion in Santa Barbara County in 1886. The geographical sequence matters. This is not evidence that every writing session occurred at Yreka, or that the events narrated in the book happened in northern California. The case concerns the claimed production of the text, anchored in the place where Oliver said it began.
Conscious dictation rather than automatic writing
The method Oliver describes is more complicated than an unconscious hand producing a finished manuscript. He says that he remained aware of his surroundings, heard the teacher and often put the ideas into his own language. He compares his role with that of a stenographer and says he learned shorthand because it would be useful. He expressly contrasts his experience with what he understood spiritualists to mean by automatic writing.
Sessions were irregular. Some allegedly occurred after he was awakened at night, using lamplight or writing in darkness. Chapters arrived out of narrative order, sometimes separated by weeks or months. His reference to writing backwards concerns the order of sentences or passages, not a claim that the surviving book consists of mirror-script. Preserving that distinction avoids turning an unusual description into a different phenomenon.
He reports two revisions and an episode in which the teacher ordered more than two hundred sheets burned before Oliver read them. He also acknowledges literary editing for publication, explaining it as the removal of his own transmission errors. These admissions are important to the history of the text. They describe a process involving selection, rewriting and loss of material, rather than an untouched record deposited in a single sitting.
The dates offered as proof
Oliver says that Mrs M. E. Moore of Louisville, Kentucky, typed the completed manuscript in duplicate in 1894 and retained one copy through midsummer 1899. He asserts that her copy remained unchanged and that evidence of this had been preserved. He also gives copyright dates of 1894 and 1899, the latter associated with a changed title. Those assertions appear in his own published account. This review has not inspected the typed duplicate, copyright deposits or an independently documented chain of custody.
The distinction becomes especially important when Oliver invokes the book’s supposed anticipation of X-rays and wireless telegraphy. To establish a prediction, a relevant passage would need securely demonstrable wording and a date preceding the development being claimed. A later statement that earlier wording was fixed is part of the claim to be checked; it cannot perform that check by itself. Broad similarities also require careful comparison with what the text actually says, rather than retrospective matching by topic.
An added prediction about electrically enhanced telescopes is explicitly assigned to a different setting: Reno, Nevada, in 1886. Oliver says he put it in a short story seen by a young woman and her family. The addendum is signed at Los Angeles on 11 October 1899. It is retained here as evidence of the way he argued for Phylos’s knowledge, without relocating the Reno episode to Yreka or treating the named but unexamined testimony as proof.
What the voice of Phylos adds
The preface includes a letter headed as being from Phylos and dated January 1886. It presents a Christian occult teacher concerned with moral instruction, the soul and the dangers of sensational writing. Its presence helps explain how the book asks to be read: as spiritually authoritative teaching and history, rather than simply an entertaining narrative.
That letter is transmitted through the same publication as Oliver’s account. It is not a separately authenticated correspondent answering him from an independently verified address. Its assertions therefore cannot be used as external corroboration of the authorship claim. Recognising this does not decide whether Oliver was sincere, consciously inventive or describing an experience he understood spiritually. The reviewed material does not establish any of those explanations conclusively.
Assessment and location
The map pin is an approximate Yreka locality reference, rounded from the Census Gazetteer, not Oliver’s home or a verified writing-session site. The account also names Santa Barbara County and Reno in its wider chronology. No private address or visitor route to a supposed session location is identified.
The outcome is Insufficient evidence for an independently existing Phylos or extraordinary knowledge supplied by that figure. The original preface documents a belief and a claimed experience in considerable detail, while leaving the essential external checks incomplete. The publication itself is real; its account of occult authorship remains unverified.
Sources and related reading
The main source is Oliver’s amanuensis’s preface, original printed pp. 13–23, including the letter attributed to Phylos and the later addendum. The 1905 Library of Congress copy supplies the published edition and title-page context. The US Census Gazetteer supplies Yreka’s locality reference (GEOID 0686944). Checked 13 November 2026.
A separate later California claim appears in Guy Ballard’s Mount Shasta account. The people, dates and claims differ. The existence of both traditions is not evidence that either independently validates the other.
