The Walnut tree (1) comes to us from sunny Italy and France, where it has grown for many centuries and is greatly prized. Its Latin name, _Juglans_, means the nut of Jove, and the Romans called it so because they thought the fruit was worthy to be set before their chief god Jove. It was brought to this country about five hundred years ago, and seems to have been grown in many districts until the beginning of last century, when there came a great demand for its wood. As much as six hundred pounds was given for a single Walnut tree, and at once all the people who had Walnut trees cut them down and sold them. This greatly reduced the number. [Illustration: PLATE XXIX THE WALNUT 1. Walnut Tree 2. Leaf Spray 3. Bud 4. Scar 5. Stamen Flower 6. Seed Flowers 7. Fruit] It is a large, handsome tree, which grows to a considerable height, and has a very thick trunk covered with grey bark. This trunk is smooth when the tree is young, but turns rugged as it grows older. The Walnut branches are large and spreading; they are sometimes twisted, but the tips of each branch always turn to the sky. For long it was thought to be dangerous to sleep beneath the shade of a Walnut tree, but for what reason I have not been able to discover. The leaves (2) are very handsome; each leaf is made up of several pairs of leaflets placed opposite each other on a central stalk, with a single leaflet at the end. When they first come out these leaflets are dull red, but the colour soon changes to a pale olive green, and each leaf is smooth and soft and has a delicious scent if crushed ever so slightly. The twigs which carry these leaves are very stout, even to the tips, but they break easily, and you will find many lying on the ground after a windy night. The bark on these young twigs is very smooth and glossy. The Walnut tree produces two kinds of flowers, which are both found on the same tree, and one kind, the stamen flowers (5), requires a whole year to ripen. If you look at the twigs which support the leaves you will see several tiny cone-shaped buds (3) dotted here and there on either side, close to the scars (4) left by last year’s leaf stalk. These are the beginnings of next year’s stamen flowers, and they remain like that all summer and all winter until the following spring. Then the bud lengthens and becomes a slender, drooping catkin (5). This catkin is covered with small flowers, each made up of five green sepals enclosing many stamens. These stamen catkins drop from the tree when the pollen dust is scattered.
