Then as some heavenly minstrel, taught to sing High notes responsive to the trembling string, To some new strain when he adapts the lyre, Or the dumb lute refits with vocal wire, Relaxes, strains, and draws them to and fro; So the great master drew the mighty bow: • And drew with ease.

Pagina 93 - ... uncouth and venomous beast, avoid a paroxysm of horror at the sight of the common house-spider.
