When the Bobbsey twins were not ice-boating they were skating, or building snow forts or snow men. Once Flossie and Freddie built a little snow house and got inside it with Snoop, the black cat, and Snap, the dog.
Everything was very nice, but the house was so small that, when they were all in it, there was not room for Snap to wag his tail. And as there never was a dog yet, with a tail, who did not want to wag it, you can easily guess what happened.
Either Snap wagged his tail in the fates of Flossie and Freddie or he whacked Snoop with it, and as the cat did not like that she ran out of the snow house.
But Snap kept on wagging his tail, and as Flossie and Freddie made him get to one side when he did it the only other place he had to wag it was against the sides of the snow house.
Now these snow sides were not very thick or strong—they were not made to be wagged against by a big dog's tail, and, all of a sudden. Snap wagged his tail right through the snow house.
