Σελίδα 30 - Flying between the cold moon and the earth, Cupid all arm'd : a certain aim he took At a fair vestal throned by the west, And loos'd his love-shaft smartly from his bow, As it should pierce a hundred thousand hearts : But I might see young Cupid's fiery shaft Quench'd in the chaste beams of the watery moon, And the imperial votaress passed on, In maiden meditation, fancy-free.
Σελίδα 30 - Yet mark'd I where the bolt of Cupid fell : It fell upon a little western flower, — Before, milk-white ; now purple with love's wound — And maidens call it, love-in-idleness l6.
Σελίδα 19 - If I do prove her haggard, Though that her jesses were my dear heart-strings, I'd whistle her off, and let her down the wind, To prey at fortune.
Σελίδα 108 - HAIL to thee, blithe spirit ! Bird thou never wert, That from heaven, or near it, Pourest thy full heart In profuse strains of unpremeditated art. Higher still and higher, From the earth thou springest, Like a cloud of fire; The blue deep thou wingest, And singing still dost soar, and soaring ever singest.

Σελίδα 93 - Tis silence all, And pleasing expectation. Herds and flocks Drop the dry sprig, and, mute-imploring, eye The falling verdure. Hushed in short suspense, The plumy people streak their wings with oil, To throw the lucid moisture trickling off, And wait the approaching sign, to strike at once Into the general choir.
Σελίδα 90 - I rest my only hope at last, And think, when thou hast dried the bitter tear That flows in vain o'er all my soul held dear, I may look back on every sorrow past, And meet life's peaceful evening with a smile ; — As some lone bird, at day's departing hour, Sings in the sunbeam, of the transient shower Forgetful, though its wings are wet the while ;— Yet ah ! how much must that poor heart endure, Which hopes from thee, and thee alone, a cure.
Σελίδα 95 - Yea, the stork in the heaven knoweth her appointed times ; and the turtle, and the crane, and the swallow, observe the time of their coming; but my people know not the judgment of the LORD.
Σελίδα 130 - The notes of this solitary bird, from the ideas which are naturally associated with them, seem like the voice of an old friend, and are listened to by almost all with great interest. At first they issue from some retired part of the woods, the glen, or mountain ; in a few evenings, perhaps, we hear them from the adjoining coppice, the garden fence, the road before the door, and even from the roof of the dwelling-house, long after the family have retired to rest.
