The Electric Light in its Infancy

I heard a woman in a ’bus boring her lover about the electric light. She wanted to know this and that, and the poor lover was helpless. Then she said she wanted to know how it was regulated. At last she settled down by saying that she knew it was in its infancy. The word “infancy” seemed to have a soothing effect upon her, for she said no more but, leaning her head against her lover’s shoulder, composed herself to slumber.
