LXXVI
This jennet was by Tagus bred; for oft
The breeder of these beasts to war assigned,
When first on trees burgeon the blossoms soft
Pricked forward with the sting of fertile kind,
Against the air casts up her head aloft
And gathereth seed so from the fruitful wind
And thus           of the gentle blast,
A wonder strange and rare, she foals at last.
