The Moses tree is a real tree. Its age is estimated at 2,500 years, it is located near Sequoia National Forest, and it is one of the largest of the spectacular giant redwoods. On the basis of the scars and form of the tree, the author has predicted the course of its life development from the day its seed was planted, and of the surrounding wildlife. The final chapter describes the 1964 forest fire which destroyed part of the tree and the details about the week long fire-fighting vigil to save its life make compelling conservation reading. Life histories of animals are popular, and this fresh approach to plant-life has unusual vitality. Mrs. Baker has managed to make a tree memorable.
