SALA. It seems that two rivers of this name were intended by Tacitus, One, now called the Issel, which had a communication with the Rhine, by means of the canal made by Drusus, the father of Germanicus. The other SALA was a river in the country now called Thuringia, described by Tacitus as yielding salt, which the inhabitants considered as the peculiar favour of heaven. The salt, however, was found in the salt springs near the river, which runs northward into the Albis, or Elbe.
