How to tell your child's book is from an earlier era:

"Ha! Who are you?" cried the bear, turning around quickly in order to see better. "Who are you, if I may ask?"

"I'm Jackie Bow-Wow," was the answer, "and if you don't at once do as I say I'll shoot you with my gun!"

...

Then Jackie burst out laughing as hard as he could.

"What's the matter?" asked Uncle Wiggily, in surprise.

"Ha! Ha!" laughed Jackie. "What a joke on that bear! I didn't have a real gun at all. It's only a wooden one, with which I was playing hunt Indians. But he thought it was a real one, and he was so scared that he let you go. Ha! Ha! Ho! Ho!"
