pulled up, which not only causes them to sweat 

 profusely, but forces them to blow hard. The 

 great absorption produced throughout their 

 whole system, by sweating, relieves them of their 

 superfluous fat, and gives room for their lungs 

 to expand : and from the increased action of the 

 lungs being so long continued, they acquire a 

 habit of quickly dilating and contracting them. 

 From these circumstances the air-cells, if not 

 actually enlarged, are improved and strengthen- 

 ed in their action to such an extent as to enable 

 horses to go at a tolerable good pace for a con- 

 siderable length (as, four miles, for example) 

 with comparative ease to themselves ; and when 

 they are drawn out or called upon to go at nearly 

 or perhaps quite the top of their pace, to finish 

 the above length, they will be found to do so 

 without feeling the least or very little dis- 

 tressed; or, if they are a little distressed on be-

 which period they may be seen to blow hard, 

 but free, clear, and strong, until they blow their

Light, delicate horses, are generally in good 

 wind, or, if not, they require but little in the way 

 of exercise to hnim them to this state ; to use the
