In dust, in rain, in cold and sultry skies: 20
Save but the grain from mildews and the flood,
Nought anxious he what sickly stars ascend.
He knows no laws by Esculapius given;
He studies none. Yet him nor midnight fogs
Infest, nor those envenom’d shafts that fly 25
When rabid Sirius fires th’ autumnal noon.
His habit pure with plain and temperate meals,
Robust with labour, and by custom steel’d
To every casualty of varied life;
