The other day, we thought we would go and have a look at the London Museum. So we got on fifty two bus in the station yard at Victoria, and started off. We had a lovely view from the top of the bus, and saw the horse guards just as they were passing Hyped Park Corner. The girls had never come this way before, and, they would have liked to explore the shops, if only there had been more time. But we had to hurry, and even then when we did get to the Museum, it was almost closing time. On the way back, John got so excited over the model beats on the Round Pond that he nearly fell in. At last he managed to drag himself away, and the girls said: "could we go back by under ground?" There was no difficulty about catching an Inner Circle train at Kensington High Street, but we had no sooner got in than we found ourselves going in the wrong direction. Of course, John wanted to stay in the train and go home the long way round, but I put my foot down and wouldn’t hear of it. In the end we got out at Baker Street, and I had to console the children by taking them to waxworks.
