Mr. and Mrs. Roberts and Carter stood on the platform to see the last of them. Jack and Jean waved handkerchiefs from the window. "Good-bye, Mrs. Bobs! Good-bye, Mr. Bobs! Good-bye, Carter!" they shouted; "we're coming back some day." Miss Dolores, very pale, bent forward, her eyes fixed on the vanishing city. Mary Lee leaned over the back of the seat and reached down a sympathizing hand to clasp the señorita's. From her place in front, Nan smiled over her shoulder. "The sun rises where we are going," she said.
