Oft, in the lone church-yard at night I've seen,
The schoolboy with a satchel in his hand,
Whistling aloud to keep his courage up…
Sudden he starts! and hears, or thinks he hears,
The sound of something purring at his heels;
Full fast he flies, and dares not look behind him,
Till out of breath, he overtakes his fellows.

The Grave (1743) l. 57
