James, who was their very own. They also had father who was just perfect never cross, never unjust, and always ready for a game at least, if at any time he was not ready he always had an excellent reason for it, and explained the reason to the children so interestingly and funnily that they felt sure he had to do it. You will think that they ought to have been very happy. And so they were, but they did not know how happy till the pretty life in the Red Villa was over and done with, and they had to live a very different life indeed The dreadful change came quite suddenly Peter had a birthday his tenth. Among his presents was a model engine more perfect than you could ever have dreamed of. The other presents were full of charm, but the engine was fuller of charm than any of the others were. Its charm lasted in its full perfection for exactly three days. Then, owing either to Peters inexperience or Phyllis's good intentions, or to some other cause, the engine suddenly went off with a bang. James was so frightened that he went out and did not come back all day. All the Noahs Ark people who were in the tender were broken to bits, but nothing else was hurt except the poor little engine and the feelings of Peter. The others said he cried over it but of course boys of ten do not cry, however terrible the tragedies may be which dadken their lot. He said that his eyes were red because he had a cold. This turned out to be true, though Peter did not know it was when he said it, the next day he had to go to bed and stay there.
