2 INTRODUCTION. 



energy to military duty may be an excellent and 

 valuable parade officer, yet in actual service, when 

 anything dashing was done, it was, in nine cases 

 out of ten, by those who loved the hunting-field 

 or the grouse-mountain far better than the bar- 

 rack-square, and that these were generally the 

 most efficient officers in an arduous campaign. 



The impetus given to the mental as well as the 

 physical powers by healthy exercise no one denies, 

 though hundreds profess themselves unable (more 

 truly, perhaps, unwilling) to submit to the ardu- 

 ous experiment. An ordinary walk is not enough 

 for a strong man who is at the same time an 

 earnest student. In order to keep his mind up 

 to the mark, he ought to accustom himself to 

 hardship, and inure his limbs and muscles to 

 fatigue. No doubt it is hard laws to a man in 

 middle life, who has never done more than his 

 " Saturday's walk," and a short stroll the other days 

 of the week, to send him up the steep mountain- 

 side with a gun under his arm ; but even he, by 

 perseverance and practice, will be astonished at 

 his own powers, and delighted with the probable 

 result health and strength of mind and body.
