"Look, look!" cried Flossie to Nan. "See what a nice ride we're having."
"Oh, look, Bert!" exclaimed Nan. "Snap really is pulling them," and she grasped her brother's arm. Bert was pulling his own sled and that of his twin sister.
"Yes, he'll pull them a little way," admitted Bert, as if he knew all about it, "and then, the first thing they know, Snap will turn around short and tip them into a snowdrift. He hasn't been trained to pull a sled, no matter how many other tricks he can do."
"I trained him myself!" declared Freddie, as he pulled on the lines to bring the dog to a stop. But Snap, seeing Nan and Bert, was eager to reach them to be patted and made much of, so he did not obey the command given by the reins, but kept on.
