passable expressions, but when they got crowded together and saw the gloomy faces the gloom spread to their faces, too.

At a picnic all are smiling and laughing. In the street car at six o'clock the long procession of workers is a stream of solemn faces. Contagion, example, surrounding, yes, that's it—contagion and example.

At six o'clock in the cars all is gloom, blueness and sorrow faces. At eight o'clock many of these faces will be changed; there will be joy, smiles, rosiness, singing and dancing. Yet the actual conditions of finance, health, hope or prospects haven't changed since these people were in the car at six o'clock.

Why then such a change in two hours?

It is this: at seven o'clock these workers sat down to supper, they were out of that gloom-reflected street car atmosphere. Now they are talking, they are rounding-up the day's activities; they are HOME with mother, sister, brother and the kiddies. The home ones greet them with smiles, the appetizing supper pleases the palate, good cheer permeates, and all is smiles and joy.

Gloom spreads gloom. Joy spreads joy. Gloom is black; joy is white. One darkens, the other brightens.

Well, then, where's the moral? What's the benefit from this little study of the street car passengers?

The lesson is plain: it is that you and I are ferments of joy or acids of gloom. We are influences to help or to hurt. To hurt others by our example hurts us. To help others by our example helps us. We become happier than ever.

In the street car life was not worth living if you judged by the pained faces. In two hours by changed thought the example of life was worth while.

What changes the mental attitude makes.
