Inscription.

When "Screw Steamers" or "Propellers" first appeared on the Great Lakes in the 1840's they quickly became the most efficient form of transportation.

Consequently, the popularity of the screw skyrocketed in the second half of the 19th century and continues in present day ship design and recreational boating,
