Four girls were walking down an elm-shaded street. Four girls, walking two by two, their arms waist-encircling, their voices mingling in rapid talk, punctuated with rippling laughter-and, now and then, as their happy spirits fairly bubbled and overflowed, breaking into a few waltz steps to the melody of a dreamy song hummed by one of their number. The sun, shining through the trees, cast patches of golden light on the stone sidewalk, and, as the girls passed from sunshine to shadow, they made a bright, and sometimes a dimmer, picture on the street, whereon were other groups of maidens. For school was out.
