I Come from Salem City is a parody of the popular song "Oh! Susanna" (1848) by Stephen Foster. The sailor version here invokes tales of the gold rush from Forty-Niners rounding Cape Horn for the San Francisco Bay. Evidently, the song saw a surprisingly long life aboard ships.

Frank Shay categorizes the song as a forecastle ballad, sung for recreation and entertainment. It was also used while working around the capstan.
