Hold Your Nose

Mary Jones (1707-1778), "Epistle, from Fern-Hill," in her Miscellanies in Prose and Verse (Oxford: Dodsley, 1750), pp. 133-138 (lines 47-56 on p. 136):

As when (to speak in phrase more humble)
The Gen'ral's guts begin to grumble,
Whate'er the cause that inward stirs,
Or pork, or pease, or wind, or worse;
He wisely thinks the more 'tis pent,
The more 'twill struggle for a vent:
So only begs you'll hold your nose,
And gently lifting up his clothes,
Away th' imprison'd vapour flies,
And mounts a zephyr to the skies.
