A third suspicious letter was in an unknown tongue and even an unknown alphabet. In the Smith diary found by Charles Ward a single oft-repeated combination of characters is clumsily copied; and authorities at Brown University have pronounced the alphabet Amharic or Abyssinian, although they do not recognise the word. None of these epistles was ever delivered to Curwen, though the disappearance of Jedediah Orne from Salem as recorded shortly afterward showed that the Providence men took certain quiet steps. The Pennsylvania Historical Society also has some curious letter received by Dr. Shippen regarding the presence of an unwholesome character in Philadelphia. But more decisive steps were in the air, and it is in the secret assemblages of sworn and tested sailors and faithful old privateersmen in the Brown warehouses by night that we must look for the main fruits of Weeden's disclosures. Slowly and surely a plan of campaign was under development which would leave no trace of Joseph Curwen's noxious mysteries.
