Forgetful of their former juice, the grape
Bears sorry clusters, for the birds a prey.
Soothly on all must toil be spent, and all
Trained to the trench and at great cost subdued.
But reared from truncheons olives answer best,
As vines from layers, and from the solid wood
The Paphian myrtles; while from suckers spring
Both hardy hazels and huge ash, the tree
That rims with shade the brows of Hercules,
And acorns dear to the Chaonian sire:
So springs the towering palm too, and the fir
Destined to spy the dangers of the deep.
But the rough arbutus with walnut-fruit
Is grafted; so have barren planes ere now
Stout apples borne, with chestnut-flower the beech,
The mountain-ash with pear-bloom whitened o'er,
And swine crunched acorns 'neath the boughs of elms.
Nor is the method of inserting eyes
And grafting one: for where the buds push forth
Amidst the bark, and burst the membranes thin,
Even on the knot a narrow rift is made,
Wherein from some strange tree a germ they pen,
And to the moist rind bid it cleave and grow.
Or, otherwise, in knotless trunks is hewn
A breach, and deep into the solid grain
A path with wedges cloven; then fruitful slips
Are set herein, and- no long time- behold!
To heaven upshot with teeming boughs, the tree
Strange leaves admires and fruitage not its own.
Nor of one kind alone are sturdy elms,
