water is eight feet deep." Advantages: With depth from edge varying, these 

 signs, together with depth markings on edge, give adequate warning to divers. 



6. Lines running entire length of pool at five-foot intervals across pool. 

 These lines are four inches wide and start at upper edge of side of pool, 

 continue to bottom, and end at edge at opposite end of pool. Lines on 

 bottom to be of asphaltum set two inches in the concrete. Advantages: This 

 is the standard method of minimizing interference in swimming races. The 

 presence of lines is an incentive for swimmers to practice keeping eyes open 

 under water and swimming in lanes or on lines. Asphaltum ensures perma- 

 nency. Painted lines, while not permanent, would effect a saving of $300. 



7. Lines across bottom of pool five feet from each end. No other cross- 

 lines. Advantages: These act as a warning to swimmers approaching end 

 of pool. Absence of other lines avoids the confusion caused when lines on 

 bottom are used to mark distances. 



8. Continuous scum gutter around entire pool, recessed in wall. Gutter 

 to be broad and deep, and cross section a continuous curve. Advantages: 

 Gutter around entire pool gives maximum of surface sanitation and pro- 

 vides handrail at all points. Broad, deep gutter prevents back splash into 

 pool, and continuous curve facilitates cleaning. 



9. All ladders at sides of pool. Advantage: Leaves ends unobstructed 

 for swimming competition. 



10. Ladders recessed flush with side of pool. Advantage: Eliminates 

 all danger to swimmers from this source, and entire 15 lanes are clear of 

 obstructions.
