Though war-signs fail in time of peace, they say,
 Two awful portents gloom the public mind:
All Mexico is arming for the fray
 And Colonel Mark McDonald has resigned!
 We know not by what instinct he divined
The coming trouble--may be, like the steed
 Described by Job, he smelled the fight afar.
Howe'er it be, he left, and for that deed
 Is an aspirant to the G.A.R.
When cannon flame along the Rio Grande
A citizen's commission will be handy.
