 he Health Magazine ] With the coming of warm weather 1.-the swimming pools and bathing 1 beaches will begin again to attract their thousands and hundreds Of thousands, instead Of the few who devote themselves 10 this sport dur 1 ing shc winter.
 Swimming is gaining increasing popularity as a wholesome form of physical exercise and relaxation, and ; the swimming pool is now associated with all sorts of clubs, athletic in sti1utions. schools and other estah- ! Ilishmcnts that promote physical wei ! fare.
 Because o' tho contacts made in swimming pools and because Of ! the possibility Of contamination Of lthc water, problems of hygiene are such as have taxed in" in gcnuity Of sanitarians. Records are available Of cpidemics of grip, cold, !, inf rf h.. ,t,I T l o' the skin due 10 swimming pool jcontamlnation.
 Chlorine in Water
 Several methods are aNailabl" for 1 the sanitary control of the water, 1 Tho rSe of chlorine, which is one Of Ithe outstanding methods, has noi solved the question entirely, as il i has the question of supplying pure water for drinking purposes. The drinking water is protected after ! treat tmcnt against being con'aminat cd again. A swimming pool is colr- tnually receiving contamination and therefore has 10 be constantly disin- fcctcd.
 Tn the University Of Wisconsin swimming pool chlorination has been used 10 control the Infection. The pool is Of standard size, 90 feet long and 20 feet wide, lined with glazed white tile and has q capacity of 5o,oo0 gallons.
 The top of the pool is two feed higher than the floor and is sur rounded by q walkway six feet wide, and with the center slightly lower than either the edge near the pool or the one at the outer edge of the walkway.
 Thus water from tho edge oi the pool is drained away through d sewer and cannot enter the pool or flow off on to the floor. It is impossible to get to the pool with out passing through shower bath situated at the shallow end.
 Filtration
 Once each day the water is hl- tered, being taken out near tn" bottom Of the deep end and pumped through a filter, then through a heater. then chlorinated and carried 10 the shallow end Of the pool. The water from q n"arby lake is used for the pool. ApproHi- matcly 200o persons us" in" pool each week. Each persons IS requlr- ed to take q soap and water shower | bath before entering.
 The pool is cleaned and scrubbed | thoroughly when the water is chang | ed; the entire walkway around In" pool is cleaned several times daily. 1 Sediment is removed each week | from the bottom of tho pool and q scum rail removes dust which col | Iccts during the night on the top Of the water.
 Regard for the Eyes
 Investigations made by W. D. stovall indicate a considerable i amount Of chlorine is necessary 10 keep the pool in a potentially. ger ! micidal condition. The amount va ries enormously with the typ" of water used. With some water it is | impossible to maintain enough l chlorine without irritating the eyes Of the swimmers.
 For this reason it Is important to consider chlorine merely as an aid | in the matter and not as a complete method for maintaining swimming l pool sanitation.
