But of greatest immediate interest was the Orne material. It took Ward only a short time to prove from identity of penmanship a thing he had already considered established from the text of the letter to Curwen; namely, that Simon Orne and his supposed son were one and the same person. As Orne had said to his correspondent, it was hardly safe to live too long in Salem, hence he resorted to a thirty-year sojourn aboard, and did not return to claim his lands except as a representative of a new generation. Orne had apparently been careful to destroy most of his correspondence, but the citizens who took action in 1771 found and preserved a few letters and papers which excited their wonder. There were cryptic formulae and diagrams in his and other hands which Ward now either copied with care or had photographed, and one extremely mysterious letter in a chirography that the searcher recognised from items in the Registry of Deeds as positively Joseph Curwen's.
