The Divining Rod: Virgula Divina—Baculus Divinatorius (Water-Witching)

In this spirited 19th‑century essay, a civil engineer steps onto the stage of a Chicago engineering club to argue that the curious practice of water‑witching deserves serious scientific scrutiny. He frames the divining rod not as superstition but as a phenomenon that might be explained through careful observation and experiment. The introduction reads like a call to open‑minded scholars, urging them to set aside prejudice and explore the hidden mechanics of this age‑old art.

The author weaves together historical anecdotes, such as the tale of two Spanish students uncovering a buried treasure, with his own notes and references to contemporary thinkers. He examines why many rational minds dismiss the unfamiliar, while others accept it without proof, and proposes a methodical approach to test the rod’s effectiveness. Throughout, the tone remains scholarly yet accessible, inviting listeners to join a thoughtful investigation rather than a sensational hunt. By the end of the first act, the groundwork is laid for a series of practical demonstrations that could reshape how engineers view folk knowledge.
