Nor these alone possess the lenient power
Of soothing life in the desponding hour.
Some favorite studies, some delightful care,
The mine with trouble and distresses share;
When of some pleasing, fancy good possessed,
Each grew alert, was busy, and was blessed.
Whether the call-bird yield the hour’s delight,
Or-magnified in microscope-the mite;
Or whether thumblers, croppers, carriers seize
The gentle mind, they rule it and they please.
—Rev. George Crabbe
Mark it all, within, without!
No tool had he that wrought,
No nail to fix, no bodkin to insert,
No glue to join; his little beak was all:
And yet how neatly finished! What nice hand,
With every implement and means of art,
Could make me such another? —A Bird’s Nest: J. HurdisJ. Hurdis 1722, May 11-1789, April 7—Pieter Camper lived.
