46. Because it is in firm (infirm).

Hark! the muffled drum sounds the last march of the brave,
The soldier retreats to his quarters, the grave,
Under Death, whom he owns his Commander-in-chief,
No more he’ll turn out with the ready relief;
But in spite of Death’s terrors or cannon’s alarms,
When he hears the last trump he’ll stand to his arms!
Farewell! brother soldiers, in peace may you rest,
