"How about public holidays; have you abandoned them?"

"Pretty generally. The occasional public holidays in your time were prized by the people, as giving them much-needed breathing spaces. Nowadays, when the working day is so short and the working year so interspersed with ample vacations, the old-fashioned holiday has ceased to serve any purpose, and would be regarded as a nuisance. We prefer to choose and use our leisure time as we please."

It was to the Leander Natatorium that we had directed our steps. As I need not remind Bostonians, this is one of the older baths, and considered quite inferior to the modern structures. To me, however, it was a vastly impressive spectacle. The lofty interior glowing with light, the immense swimming tank, the four great fountains filling the air with diamond-dazzle and the noise of falling water, together with the throng of gayly dressed and laughing bathers, made an exhilarating and magnificent scene, which was a very effective introduction to the athletic side of the modern life. The loveliest thing of all was the great expanse of water made translucent by the light reflected from the white tiled bottom, so that the swimmers, their whole bodies visible, seemed as if floating on a pale emerald cloud, with an effect of buoyancy and weightlessness that was as startling as charming. Edith was quick to tell me, however, that this was as nothing to the beauty of some of the new and larger baths, where, by varying the colors of the tiling at the bottom, the water is made to shade through all the tints of the rainbow while preserving the same translucent appearance.

I had formed an impression that the water would be fresh, but the green hue, of course, showed it to be from the sea.

"We have a poor opinion of fresh water for swimming when we can get salt," said the doctor. "This water came in on the last tide from the Atlantic."

"But how do you get it up to this level?"

"We make it carry itself up," laughed the doctor; "it would be a pity if the tidal force that raises the whole harbor fully seven feet, could not raise what little we want a bit higher. Don't look at it so suspiciously," he added. "I know that Boston Harbor water was far from being clean enough for bathing in your day, but all that is changed. Your sewerage systems, remember, are forgotten abominations, and nothing that can defile is allowed to reach sea or river nowadays. For that reason we can and do use sea water, not only for all the public baths, but provide it as a distinct service for our home baths and also for all the public fountains, which, thus inexhaustibly supplied, can be kept always playing. But let us go in."

"Certainly, if you say so," said I, with a shiver, "but are you sure that it is not a trifle cool? Ocean water was thought by us to be chilly for bathing in late September."

"Did you think we were going to give you your death?" said the doctor. "Of course, the water is warmed to a comfortable temperature; these baths are open all winter."

"But, dear me! how can you possibly warm such great bodies of water, which are so constantly renewed, especially in winter?"
