Uncle Cliff's "dangerous" box yielded still more wonders. The noisy bombs and giant crackers of the morning were followed by pyrotechnics that aroused unbounded admiration from the grown-ups and caused an excitement among the small greasers that threatened to end in a human conflagration. A small fortune went up in gigantic pin-wheels; flower-pots that sent up amazing blossoms in all the hues of the rainbow; rockets that burst in mid-air and let fall a shower of coiling snakes, which, in their turn, exploded into a myriad stars; Roman candles that sometimes went off at the wrong end and caused a wild scattering of the audience in their immediate vicinity; and "set-pieces" that were the epitome of this school of art. It would have been hard to say which was most tired, the hostess or her guests, when the last spark faded from the big "Lone Star" of Texas which ended the show. No bedtime frolic to-night; the four in the nursery undressed in a dead quiet and fell asleep before their heads fairly touched the pillows. In her own little room Sarah held another seance with the witch hazel bottle, and went to sleep only to dream of a wild ride across the meadows on Blue Bonnet's rocking-horse, with a fierce band of Comanche Indians pursuing her, yelling fiendishly all the while, and keeping up a mad fusillade of Roman candles. CHAPTER IV THE ROUND ROBIN "WHAT'S the program for this morning?" asked Uncle Cliff, as the ranch party assembled on the veranda after a very late breakfast. "I don't know what the others are going to do," said Sarah, "but I'm going to write letters." The other girls exchanged amused glances: it was evident that Sarah wished to forestall suggestions of another ride. Kitty was beginning to show symptoms of sauciness when Mrs. Clyde interrupted kindly with--"I think Sarah's suggestion quite in order. Every one at home will be looking for letters." "Uncle Cliff telegraphed," said Blue Bonnet, loath to settle down to so prosaic a pursuit. "But a telegram isn't very satisfying to mothers and fathers, dear," replied her grandmother. "And think of poor Susy and Ruth." "I intend to write them, too," remarked Sarah. "Let's all write them!" exclaimed Blue Bonnet. "That's the right spirit," said Senora with an approving nod. "A 'round-robin' letter will cheer the poor girls wonderfully." "You hear the motion, are all in favor?" asked Alec. "Will you write a 'robin,' too?" bargained Kitty, who loved to torment the youth. "Sure!" he agreed at once, thus taking the wind out of her sails. "Aye, aye, then!" they all exclaimed, and the motion was declared carried.
