 bject little satisfaction is to be found. Ingenious men will readily advance plausible arguments to support whatever theory they shall choose to maintain; but then the misfortune is, every one's hypothesis is each as good as another's, since they are all founded on conjecture. The late writers of this sort, in whom may be seen all the arguments of those that have gone before, as I remember, stock America from the western coast of Africa and the south of Europe; and then break down the Isthmus that bridged over the Atlantic. But this is making use of a violent piece of machinery: it is a difficulty worthy of the interposition of a god! 'Incredulus odi.'

The Naturalist's Summer-evening Walk

... equidem credo, quia sit divinitus illis Ingenium. Virg. Georg.

When day declining sheds a milder gleam, What time the may-fly * haunts the pool or stream; When the still owl skims round the grassy mead, What time the timorous hare limps forth to feed; Then be the time to steal adown the vale, And listen to the vagrant** cuckoo's tale, To hear the clamorous*** curlew call his mate, Or the soft quail his tender pain relate; To see the swallow sweep the dark'ning plain Belated, to support her infant train; To mark the swift in rapid giddy ring Dash round the steeple, unsubdu'd of wing: Amusive birds!--say where your hid retreat When the frost rages and the tempests beat; Whence your return, by such nice instinct led, When spring, soft season, lifts her bloomy head ? Such baffled searches mock man's prying pride, The God of Nature is your secret guide! While deep'ning shades obscure the face of day To yonder bench, leaf-shelter'd, let us stray, Till blended objects fail the swimming sight, And all the fading landscape sinks in night; To hear the drowsy dor come brushing by With buzzing wing, or the shrill**** cricket cry; To see the feeding bat glance through the wood; To catch the distant falling of the flood; While o'er the cliff th' awakened churn-owl hung Through the still gloom protracts his chattering song; While high in air, and pois'd upon his wings, Unseen, the soft enamour'd woodlark***** sings: These, Nature's works, the curious mind employ, Inspire a soothing melancholy joy: As fancy warms, a pleasing kind of pain Steals o'er the cheek, and thrills the creeping vein! Each rural sight, each sound, each smell combine; The tinkling sheep-bell, or the breath of kine; The new-mown hay that scents the swelling breeze, Or cottage-chimney smoking through the trees. The chilling night-dews fall: away, retire; For see, the glow-worm lights her amorous fire!****** Thus, ere night's veil had half obscured the sky, Th' impatient damsel hung her lamp on high: True to the signal, by love's meteor led, Leander hasten'd to his Hero's bed.*******

I am, etc. (*The angler's may-fly, the ephemera vulgata Linn., comes forth from its aurelia state, and emerges out of the water about six in the evening, and dies about eleven at night, determining the date of its fly state in about five or six hours. They usually begin to appear about the 4th of June, and continue in succession for near a fortnight. See Swammerdam, Derham, Scopoli,
