Christian lived in the largest city in Denmark. We call that city Copenhagen, but Christian calls it Kjøbenhavn (Kuvn havn). Christian was not the only boy in that city who was excited on that July day. Many boys, and girls too, were leaving the city for a summer on a farm. They were not going to visit aunts or uncles or grandfathers. No, their visits were going to be more exciting even than visits to aunts and uncles and grandparents would be, for many of them were going to be guests of families whom they had never seen. Those boys and girls live in very poor homes in the city. When school closes for summer vacation, there is little for them to do. Their homes are small and there are few places near their homes where they can play. So every summer farmers invite boys and girls from the city to be their guests for four weeks of their vacation. The officials of the railroads and of steamship lines give those boys and girls free rides on the trains and boats to the farms. Perhaps Christian was happier than many of the boys. Only a few weeks earlier a letter had come to him from the farmer whom he had visited the summer before. The letter said, “All of us here on the farm want you to come to us again this summer. I think that even the cows, the chickens, the ducks, and the geese missed you when you left last August.” No wonder Christian was excited and happy! Morning came at last and Christian started very early on his journey to the farm. He carried only a small bag of clothes with him, so he and his mother went to the station on a street car. He passed through the gate at the station and waited on the platform for his train. Other boys and girls were waiting too. Soon they were on the train scrambling for seats by a window for they were eager to see as much of Denmark as they could. Christian had almost a whole day’s journey to the farm. Denmark is made up of hundreds of small bodies of land with water separating them. To reach the farm Christian had to travel on two trains and two boats. Christian was interested in all that he saw. He was not surprised to see the wide stretches of flat land, but after visiting farms of Norway you may be surprised. Christian saw a field in which black and white cows were eating the green grass. He could see far, far away across that pasture. The land was as level as a floor, with not even a tiny hill in sight. At other places he did see hills—no very high ones though. That hilly land looks very little like land of Norway made by the giants. But the same ice-sheets did make these hills. As the glaciers that covered Denmark melted, they left behind these piles of rocks and soil which we call hills.
