Let This New Chair Add to Your 

 Bathing Convenience 



MR. FRANK BEHM, of Toledo, 

 Ohio, has invented an adjustable 

 chair for the bathtub. As the 

 accompanying cut shows, it can be 

 hooked on the end of the tub, the 

 user reclining somewhat at ease, 

 above tide level, while 

 he performs his ablu- 

 tions at leisure. 



But the use of this 

 appurtenance is not 

 necessarily confined 

 to the bath. Hooked 

 on the rail of the 

 back piazza it would 

 do for a small-tub 

 stand while washing 

 out baby's stockings. 

 Attached to a rail 

 fence at a Sunday 

 School picnic it might 

 save the lunch from 

 the ants. 



A New Automobile 

 Cigar-Lighter 



THE new type of electric cigar-lighter 

 shown in the accompanying illus- 

 tration is designed to be mounted either 

 on the dash or on the rear of the front seat 



of an auto- mobile. In 



either case it x^sttH^^ is attached 



to a cord which is automatically wound up 

 on a reel, enclosed in a case which forms 

 the back of the plate on which the cigar- 

 lighter is held. 



The lighter is prevented from rattling 

 while the car is in motion by means 

 of a small spring-clip attached to 

 the face plate of the mounting. 

 Current is obtained from the bat- 

 tery in the car. 



This legless chair hooks 

 over the edge of the tub 



A reel in the rear of the case winds up the 

 cord when the cigar-lighter is not in use 



The Germs in a 

 Swimming Pool 



PUBLIC baths 

 and swim- 

 ming pools are a 

 source of both bene- 

 fit and pleasure to a 

 community, but they 

 are exceedingly dan- 

 gerous to health un- 

 less they are kept in 

 a sanitary condition. 

 Water which has 

 been contaminated 

 by sewage is al- 

 ways unsafe for bath- 

 ing purposes. An- 

 other source of con- 

 tamination is from the bathers them- 

 selves. The water of a Liverpool bath 

 was examined to determine how much the 

 bathers contaminated it. It was found 

 that each bather contriblited about 

 4,000,000 germs to the water of the swim- 

 ming pool in ten minutes. In the second- 

 class baths which are patronized by small 

 boys, it was found that each bather added 

 6,000,000,000 germs to the pool during a 

 similar period. At the end of the day, 

 the water held no less than 4,676 germs 

 per cubic centimeter. 



The germs which are a danger to health 

 are those of intestinal origin. The pres- 

 ence of other bacteria does not make the 

 swimming pool unsafe. If the water is 

 treated with chloride of lime it can be 

 rendered perfectly sterile. When certain 

 precautions are taken and the bathers 

 themselves instructed in the rudiments of 

 personal cleanliness, there is no reason 

 public swimming pools should not be of 

 great benefit to a crowded community, 

 especially during the uncomfortably hot 

 summer months when cool baths do so 

 much to make the heat bearable.
