The girls nodded, but said nothing.
"Gracious! Did you see that?" called Ruth, with a trace of excitement in her tone.
"No, no. What is it?" cried the girls.
"Oh, nothing, only I ran down a cow," answered the fair driver, trying to speak carelessly.
"Ran down a cow!" exclaimed Bab, peering through the curtain windows.
"You needn't look for her. She is a mile or more back now. I didn't run over her. She appeared so suddenly out of the snow cloud that I didn't see her until the car was almost on top of her. I must have hit her only a glancing blow, for I barely felt the jar. I hope I didn't hurt the poor thing."
"So long as we keep on four wheels, please don't interrupt us," begged Miss Presby severely, whereat there was a series of giggles from the girls. "Where was I, girls?"
"Still at Chicago," replied Mollie. "You were speaking of your ancestor's prophecy."
"Oh, yes. At the time they were living in the garrison, at the first fort ever built on the Chicago River. You know the Indians were pretty thick hereabouts at that period."
"Indians!" murmured Grace apprehensively.
