CHAPTER XXIV 



THE EARS AND HOW TO PROTECT THEM 



THE ears are also very important windows of Jack's 

 House. Just how much good hearing contributes to 

 our usefulness and pleasure, no one can fully appreciate 



until he becomes 

 deaf. There are 

 occupations in 

 which only per- 

 sons having the 

 ability to hear 

 well can be em- 

 ployed, and, to 

 be fitted for 

 these, our ears 

 must be in 

 healthy condition. Indeed, there are few lines of work 

 in which inability to understand readily in conver- 

 sation is not a handicap, hence even slight deafness 

 may be a hindrance in almost any business. But the 

 worst feature of slight derangement of hearing is 

 that it may gradually lead to greater or even to total 

 deafness.
