Record and sharpen your observations of nature in our beautifully illustrated, spiral-bound Calendar of Firsts. Mason wrote:

“It is a capital plan for the children to keep a calendar—the first oak-leaf, the first tadpole, the first cowslip, the first catkin, the first ripe blackberries, where seen, and when. The next year they will know when and where to look out for their favourites, and will, every year, be in a condition to add new observations. Think of the zest and interest, the object, which such a practice will give to daily walks and little excursions.”
