Ethel Blue nodded, for she saw that the change was almost as if a sheet of colored glass had been held over a strong electric light.

“Sometimes during a thunder shower,” she said, “I’ve seen awfully queer colors over in that meadow.”

“The air is charged with electric particles sometimes,” explained Miss Daisy, “and you are looking through them. You get different color effects during an ordinary rain storm, too.”

“I think rain over that meadow is going to be one of the prettiest things Dorothy will see from this terrace,” said Ethel Blue.

“She will have a long sweep to watch and a shower moves sometimes fast and sometimes slowly, so there will be opportunity to notice many changes,” suggested Miss Graham.

“I wonder if Aunt Louise is going to have electric lights out here on the porch,” said Ethel Blue. “They will draw the mosquitoes like everything.”

“But she won’t mind that because she can stay inside of her wire cage,” answered Miss Daisy. “Surely she’s going to have electric lights. Don’t you see the wires already put in?”

“Of course,” answered Ethel Blue. “How stupid of me! Those black ends are poking out all over the house and somehow I never thought what they were for.”

“Then you haven’t noticed the lighting scheme that your Aunt and Dorothy have worked out. Let’s walk through the house now, and see just how she has arranged it.”

They went through the door of the screen into the enclosed portion and then into the dining room.
