The "Error of the Day" may be defined as the "The difference between
the distance or range which must be put upon the sights in order to
hit the target and the actual distance from the gun to the
target."--_Admiralty Note._
A great naval gun never fires twice alike. It varies from day to day,
and expert allowance has to be made in sighting every time it is
fired. Variations in atmosphere, condition of ammunition, and the
wear of the gun are the contributory causes to the ever-varying
"Error of the Day."
"Say, ain't he pretty?"
"A Jim-dandy--oh, my!"
"What's his price in the open market?"
"Thirty millions--I think not."
