When he reached the gate, he found the monkey sitting up rubbing his head with his forefoot and running slowly toward home on three legs. Seeing he was all right, the doctor whistled for Zip to come, but no Zip appeared. So after calling him once or twice more, the doctor concluded he did not wish to come back for fear the monkey would get him again and try to take a free ride.
"He probably has trotted home across lots," thought the doctor, "or else he may be waiting for me part way home."
On hearing the doctor whistle, the monkey ran to the side of the road, jumped up on the fence and ran along its top until he reached Miss Belinda's yard. Once there, he ran up a tall tree to a place of safety, where no dogs could reach him, and there the doctor left him, rubbing his head.
As Zip trotted home across lots, he made up his mind that he would go to Miss Belinda's every day until he had a chance to get even not only with Polly, but with the monkey too. For I am sorry to say that Zip was a very revengeful dog, and he never forgot an injury, at least not until he had paid back in like coin anything he had suffered.
"You may rest assured," he said to himself, "that I shall take one at a time, however, and look around well before tackling either one, to see that the other is nowhere about."
Miss Belinda was out when all this happened, so was very much alarmed when she returned to see Peter-Kins hopping around on two legs, holding his head with his hands. And still more so when she took him in her arms and saw that there was a big bump on his forehead the size of a hen's egg, which was still swelling and by this time threatening to close one eye.
"You poor darling little pet! Did you fall out of the tree and bump your head? I is so sorry," and talking such baby talk to him, she carried him off into the house to put witch hazel and a bandage on his head.
All this time Polly kept screaming, "Help! Help! Help!"
"Someone must have thrown a stone and hurt Peter-Kins," decided Miss Belinda, "or Polly would not be calling for help. The next time I go out, I will shut them in the house so nothing can happen to them."
