'Tis not enough that Greek and Roman page
At stated hours the sprightly boy engage;
E'en in his pastimes he requires a friend,
To warn, and teach him safely to unbend;
And levying thus, and with an easy sway,
A tax of profit from his very play,

To impress a value, not to be erased,

On moments, squander'd else, and running all to waste.

COWPER'S Tirocinium.

BEING AN ATTEMPT TO IMPLANT IN THE YOUNG MIND THE FIRST
PRINCIPLES OF NATURAL PHILOSOPHY BY THE AID OF

THE POPULAR TOYS AND SPORTS OF YOUTH.
