SCALES OF DIET. 183 



in the case of a hunter turned out in summer, or a polo pony 

 at grass during winter, we should supplement his open-air 

 food with a moderate quantity of corn, say, about 5 Ib. This 

 addition will have no " heating " effect ; because the extra 

 nourishment received into the system will become "worked 

 off" by the increased exercise which the animal will take 

 in response to the stimulating action of the corn. This 

 voluntary exercise, supposing the animal to be sound, will be 

 of great benefit in keeping up his condition, which once lost, 

 takes a long time to regain. A horse cannot maintain life on 

 straw as his only food. 



Healthy horses which take no exercise, such as those on 

 board ship, may get either of the following rations, according 

 as carrots can or cannot be obtained :- 



Oats . . '. . ... . . 3 Ib. 



Hay 18 



Bran ......... 5 ,, 



Linseed ......... 3 oz. 



The linseed may be given as a mash or as linseed tea from time to time, or as 

 meal. 



Or, 



Oats 4lb. 



Hay . 12 ,, 



Bran 2 ,, 



Carrots . . . . . . . . . 7 ,, 



With this ration there is no need to give a mash. 



2. Horses in Light Work.

 heading we may take cavalry horses during peace time :

The hay might with advantage be increased to 15 or 16 Ib.
