Photograph of a United States Army Corps of Engineers sign for Lock and Dam No. 24 along the Mississippi River at Clarksville, Missouri. The photograph was taken on board the steamboat DELTA QUEEN.
Photograph of the view from the sun deck. Note the tow boat and barges to the right of the flag staff near the shore line. The steamboat DELTA QUEEN would catch up with them later in pictures.
Paddlewheel nearly stopped, the Queen eases into the auxiliary chamber at Alton, her early-rising passengers gathering on the forward promenade deck to observe the activity and admire the skill of her master as she glides silently into the chamber.
Some say the paddlewheel is the most efficient means of marine propulsion ever devised; no one will argue that it is the most picturesque. No words can describe the symphony of motion as the pitman travels back and forth; the crank and eccentrics turn, and as she gathers speed, the spray irrigates the mint patch.
