Strona 392 - Yon cottager who weaves at her own door, Pillow and bobbins all her little store, Content though mean, and cheerful, if not gay, Shuffling her threads about the live-long day, Just earns a scanty pittance, and at night Lies down secure, her heart and pocket light...

Strona 11 - Tis chastity, my brother, chastity : She that has that is clad in complete steel, And, like a quivered nymph with arrows keen, May trace huge forests, and unharboured heaths, Infamous hills, and sandy perilous wilds ; Where, through the sacred rays of chastity, No savage fierce, bandit, or mountaineer, Will dare to soil her virgin purity.
Strona 42 - In prose compositions, this figure requires to be used with still greater moderation and delicacy. The same liberty is not allowed to the imagination there, as in poetry.
