THE IMPORTANCE OF LIGHT 29 



the end of May, and I never in my life have 

 shut out the air or the light from them. This 

 matter of light, by the way, is one I attach 

 the greatest importance to. So much so, 

 that in my place at Newmarket I had the 

 lower part of the door so arranged — the 

 whole door was made of strong galvanized 

 wire netting — that sheets of plate-glass could 

 be inserted in winter on the outside of the 

 wire netting, so as to let in the full benefit of 

 the sun's rays, and yet not have the horse 

 too cold. You remember the importance 

 I attach to light as being the best of all 

 germicides. From your point of view — for 

 you are not in Newmarket, where coughing 

 is endemic — you need only have the top 

 door always open, or, better still, taken away 

 altogether. 



Many bad stable habits are at once cured 

 if you let the horse see out all day ; and, 

 when we think of it, is it not terribly bad 

 treatment for the poor horse to leave him 

 twenty hours out of the twenty-four in almost 

 or in complete darkness ? I should like to help
