80 ON VENTILATION. 



but this, of course, arises more from the heat of the 

 atmosphere than from that of the horses. At this 

 season of the year, the shutters should be closed by 

 day, to keep out the sun, but the apertures for the ad- 

 mission of pure air should all be kept open, as should 

 also those for letting out the foul air. At night it 

 may be necessary to close them to a certain extent, 

 but the groom in this respect should be guided by the 

 appearance of the night, as well as by the indications 

 of the thermometer ; and, on such occasions, he is to 

 use his own judgment accordingly. 



It is in the hot summer months that the summer 

 clothing comes into use, in the stables as well as out of 

 them, for such horses as may require the change ; and 

 it will, of course, be necessary to diminish the quan- 

 tity, in regard to such as require the winter clothing to 

 be continued ; to a single quarter piece, for example ; 

 but when they go out, a hood and breast-cloth can be 

 added, either a linen or a woollen one, as the groom 

 may best approve. When clothing the horses up at

 delicacy or strength and constitution of the different 

 horses, as also by the appearance of the thermometer ; 

 but at the season of the year to which I am alluding, 

 race-horses have, most of them, been drawn fine by 

 physic and strong work. From these circumstances, 

 they are generally in good health, or rather they are
