Death loves a shining mark, a signal blow. [ Young ]

They know the time to go!
The fairy clocks strike their inaudible hour
In field and woodland, and each punctual flower
Bows at the signal an obedient head
And hastes to bed. [ Susan Coolidge ]

Ships that pass in the night, and speak each other in passing.
Only a signal shewn and a distant voice in the darkness:
So on the ocean of life we pass and speak one another.
Only a look and a voice, then darkness again and a silence. [ Henry Wadsworth Longfellow ]

A blush is no language: only a dubious flag-signal which may mean either of two contradictories. [ George Eliot ]

The highest mark of esteem a woman can give a man is to ask his friendship; and the most signal proof of her indifference is to offer him hers.

Stillness of person and steadiness of features are signal marks of good breeding. Vulgar persons can't sit still, or, at least, they must work their limbs or features. [ Holmes ]

There is power in love to divine another's destiny better than that other can, and by heroic encouragements hold him to his task; what has friendship so signal as its sublime attraction to whatever virtue is in use. [ R. W. Emerson ]

Ostentation is the signal flag of hypocrisy. The charlatan is verbose and assumptive; the Pharisee is ostentatious, because he is a hypocrite. Pride is the master sin of the Devil; and the Devil is the father of lies. [ Chapin ]

Bear your burden manfully. Boys at school, young men who have exchanged boyish liberty for serious business - all who have got a task to do, a work to finish - bear the burden till God gives the signal for repose - till the work is done, and the holiday is fairly earned. [ James Hamilton ]
