"All ready!" replied Billy.

"But how are you to get out?"

"We will show you," said Stubby, whereupon Billy hopped up on the packing box and from it onto the roof of the shed and then jumped down into the alley.

"Very cleverly done!" commended the cat, whose name, by the way, was Tiger because he was striped like one. "But what puzzles me is how your friends are to get out as the jump is too high for them."

"Too high for them, did you say? Nothing is too high for a dog that has done police duty in France. Listen! Did you not hear something hit the fence and then the scratch of nails on the boards? Well, that is my friend Stubby running up the side of the fence. From the sounds, evidently he did not get enough of a running start and fell back. But here he comes! See his head appearing over the top?"

In a second Stubby appeared, balancing himself on the ridge of the fence. The next moment he stood beside them. At the same time Button also ran down a post of the fence.

"Now we are all here, we'll have to hurry to allow for having to stop to hide when we see watchmen and strange dogs. Not knowing any of our members, you will have to be careful not to attack them, thinking they are enemies. I will give you the password. It is three short, sharp barks. On seeing another dog, all our members bark this password and if the dog they bark at does not reply in like manner, they know it is a stray dog. The cats all give three caterwauls in the same manner."

"Oh," exclaimed Button, "here comes a brute of a bulldog, whose mouth looks as if it were just watering for the back of a cat. Unless he gives the password quickly I shall take no chance but run up this tree. I am willing to tackle almost any dog but a bulldog."

"Bow! Wow! Wow!" barked the bulldog as he approached them.

"Bow! Wow! Wow!" replied Stubby, while Billy baaed, "Baa! Baa! Baa!" and Button meowed, "Mew! Mew! Mew!"
