Charlotte Mason was an educator in England in the last century, and one of her main educational methods was to have every student keep a Nature Notebook or Nature Diary---a record of the natural world as the children observed it first-hand. The student's Nature Notebooks were filled with poetry, prose, line drawings and watercolors.
"The Country Diary of an Edwardian Lady" is the perfect example of a fully developed Nature Diary. The author went out amid the English countryside and recorded what she observed---the flowers, trees, birds, insects.
The artistry of the drawings and watercolors in this is absolutely breathtaking. If you're looking for an introduction to the idea of Nature Diaries, or you simply enjoy a book of true grace and beauty, then this is the book for you.
