Just such a happy, useful life is found in this little story. Gerda and her twin brother take a trip northward across the Baltic Sea with their father, who is an inspector of lighthouses. On their way they meet Karen, a little lame girl. After going farther north, into Lapland, where they see the sun shining at midnight, and spend a day with a family of Lapps and their reindeer, Gerda takes Karen home to Stockholm with her so that the child may have the benefit of the famous Swedish gymnastics for her lameness. Then such good times as the three children have together! They go to the winter carnival to see the skating and skiing; they celebrate Yule-tide with all the good old Swedish customs; and there is a birthday party for the twins, when Karen also receives a gift,—the very best gift of all.
