To man made for labour, due intervals of relaxation are 

 no less necessary, than sleep is to the body when exhausted 

 by watching ; and truly unhappy may that mortal be reck- 

 oned, to whom nothing affords amusement. He who is ex- 

 hausted by the more weighty labours, has the greatest need 

 of rest ; but rest, not tempered with pleasure, becomes tor- 

 pid insensibility. The principal reward of labour, which the 

 Creator has granted to man, is leisure with enjoyment ; and 

 mortals generally exert their utmost efforts to obtain it. 

 Reflections on the Study of Nature, translated from the Latin 

 of Linn&us by Sir J. E. Smith.
