"Are there street-cars?" asked Katrina.

"Street-cars? Why, child, there are street-cars to burn—electric ones, too. I felt grievously defrauded. I wanted a mule tram."

"The mule is an unfashionable animal," said Mrs. Carroll. "Time was when a handsome pair of mules was considered not unsuitable to draw a gentleman's carriage."

"The farmers aren't using them so much, either," said Bob. "They're too unreliable. Horses are cheaper, too."

"I saw some very decent saddle-horses in town—of their kind."

"What's their kind?"

"Long-tailed single-footers, Katrina."

"The easiest gait in the world," put in Bob, combatively, disregarding the tails.

"It looks so. And not a Derby hat in the whole place except mine."

"And not a silk one, except on colored coachmen," added Sydney, maliciously.
