70 NATURAL HISTORY 
Thefe, NATURE'S works, the curious mind employ, 
Infpire a fooching melancholy joy : 
As fancy warms, a pleafing kind of pain 
Steals o'er the cheek, and thrills the creeping vein ! 
Each rural fight, each found, each fmell, combine ; 
The tinkling flieep-bell, or the breath of kine; 
The new-mown hay that fcents the fwelling breeze. 
Or cottage-chimney fmoking through the trees. 
The chilling night-dews fall : — away, retire ; 
For fee, the glow-worm lights her amorous fire ' ! 
Thus, e'er night's veil had half obfcur'd the iky, 
Th' impatient damfel hung her lamp on high : 
True to the fignal, by love's meteor led, 
L>eander haften'd to his Hero's bed 
I am, &c. 
LETTER XXV. 
TO THE SAME. 
DEAR SIR, Selborne, Aug. 30, 1769, 
It gives me fatisfaftion to find that my account of the ot^fel 
migration pleafes you. You put a very Ihrewd queftion when you 
alk me how I know that their autumnal migration is fouthward ? 
> The light of the female glow-worm (as flie often crawls up the ftalk of a grafs to 
make herfelf more confpicuous) is a fignal to the male, which is a flender dulky 
Jcambaus.
