| C.N. Douglas, comp. Forty Thousand Quotations: Prose and Poetical. 1917. | | | | Vigilance |
| | | The masters eye makes the horse fat. From the Latin. | 1 |
| It is the enemy who keep the sentinel watchful. Mme. Swetchine. | 2 |
| Vigilance is not only the price of liberty, but of success of any sort. Beecher. | 3 |
| He is most free from danger, who, even when safe, is on his guard. Syrus. | 4 |
| There is a significant Latin proverb, to wit, Who will guard the guards? H. W. Shaw. | 5 |
| A prudent person, having to do with a designing one, will always distrust most when appearances are fairest. Richardson. | 6 |
| | Chance will not do the work. Chance sends the breeze; |
| But if the pilot slumber at the helm, |
| The very wind that wafts us towrds the port |
| May dash us on the shoals. The steersmans part |
| Is vigilance, or blow it rough or smooth. |
Ben Jonson. | 7 | | |
