"I agree with you," the mate probably hissed in answer. "We have no peace or quietness at all, with this dog chasing us at unexpected times. Let's teach him a lesson!"

And that is what they were trying to do—teach Ruddy a lesson. The swans wanted to make Ruddy afraid of them, so he would no longer chase them.

When a cat, I don't mean Sallie, especially, but any cat, wants to teach a dog a lesson, and cause him to fear her, so he will no longer chase her, the cat turns, arches up her back, makes her tail as large as she can, hisses at the dog and scratches his nose if possible. A cat seems to understand that a dog's nose is his most tender spot, as indeed it is. A dog really hates to have his nose scratched as it bothers him, hurts him and prevents him from smelling his best, and on a dog's scent, or sense of smell, nearly everything depends.

But swans can't scratch. They can pinch with their yellow bills, or, if they are black swans, with their red beaks. And they can deal hard blows with their powerful wings.

And as Ruddy raced along the shore, back toward where he had left Rick, the dog tucked his tail between his hind legs to keep it out of the way. Next to a dog's nose his tail is his most tender part.

Ruddy did not want his tail pinched, or nipped, but that is just what happened. One of the swans managed to get close to the dog, who was running away as fast as he could, and, catching the setter's tail in his strong beak, gave it a hard bite.

My, how Ruddy howled! He howled more than once, and then he ran so fast and hard that he pulled his tail out of the swan's beak. Ruddy was loose. The swan had done what he hoped to do.

Then the first swan, and all the others, stopped chasing Ruddy. They spread wide their wings to act as brakes, just as an airship man pulls down the tail rudder of his aeroplane to make it travel over the ground more slowly when he has made a landing. Birds, too, when they alight after a fly, spread wide their tails. Just watch them some time.

Then, having, as they hoped, taught Ruddy a lesson, so he would not tease them again, the swans waddled back to the lake.

The setter dog had a queer expression on his face. He held his head on one side, one long, silky ear was cocked up and Ruddy seemed very much surprised by what had happened. In fact he appeared very much ashamed of himself, and animals can be ashamed just as much as can boys or girls. If you have ever seen a cat, sleeping on the edge of a chair, and, perhaps while she was dreaming of something, suddenly slip off to the floor, you know what I mean. The cat is ashamed of having fallen out of bed. It was this way with Ruddy. He was ashamed of having run away from the swans.
