"There is a great deal to be learned about trees," said Miss Harson, when all were comfortably seated in the pleasant schoolroom; "and, besides the natural history of their species, some old trees have wonderful stories connected with them, while many in tropical countries are so wonderful in themselves that they do not need stories to make them interesting. The common trees around us will be our subjects at first; for I suppose that you can scarcely tell a willow from a poplar, or a chestnut tree from either, can you?"
