HyGrene or INDOOR SWIMMING PooLs, WITH SUGGESTIONS FOR 
PracticaL DistNFECTION. 
By SEVERANCE BURRAGE. 
The “Ole Swimmin’ Hole” of our boyhood days is doomed. The fa- 
vorite spot in pond or stream to which we used to go after school for a 
good swim and play, with no thought for the microbe in the water nor the 
bathing suit for our bodies, is, for the boy of today almost unknown, and 
for the boy of the future will be but an unrealizable dream. With the 
udvance of civilization these swimming heles are being replaced by public 
bath-houses, and to these, or to gymnasiums that are provided witli 
swimming tanks, the boys must go for their swim. The streams and 
pouds have become polluted to such an extent that it is dangerous for 
the boys to bathe therein. This is the result of the increase in population, 
coupled with the great carelessness of individuals and communities in the 
disposal of wastes. This replacement of the natural swimming pool by 
the indoor swimming pool may carry with it new unhygienic conditions, 
and it is a discussion of these conditions and their elimination that forms 
the purpose of this paper. 
CONSTRUCTION OF INDOOR SWIMMING POOLS. 
One of the first requirements in the sanitary construction of the indoor 
Swimming pool is that it must be so constructed that it may be easily 
cleaned. To this end the surface of the lining material of the pool should 
be very smooth, such a surface as is provided by glazed tiles so laid as 
to avoid all cracks and crevices. At the angles formed by the meeting of 
the sides and fioor of the pool, curved tiling should be used, which would 
give the same result in the border of the pool flooring as is obtained in 
the angleless baseboard in up-to-date hospitals and operating rooms. The 
almost universal deposit of a slimy sediment in these pools, even when 
the water is comparatively clear, makes it necessary to provide for an 
easy and complete cleaning. A concrete or cement lining, made as smooth 
as it is possible to make it, furnishes a surface that is difficult to keep 
clean.
