The birds spread the seeds of the wild plums as they do those of the cherries. The kernels of all these seeds are bitter and contain a very poisonous substance. Cherry trees have beautiful white blossoms that come early in the spring, and the peach trees have lovely pink blossoms. The peaches bloom the earliest of all, and as their flowers come out before the leaves, they turn the world into a maze of pink beauty in the parts where the peach orchards are. [Illustration: Wild plum.] APPLES. Apples have tough cores in which their somewhat delicate seeds are protected. When we eat apples we throw the cores away. We now know that this is just what the apple wants. [Illustration] If the core is tossed into a hedge by the roadside, its seeds may get a chance to sprout, and indeed they often do, for in the country we often come upon apple trees in out-of-the-way corners, where they were not planted by man on purpose. Apples do not grow wild in this country, excepting crab apples. No doubt the birds carry away the ripe crab apples and drop the cores. [Illustration] Pears and quinces have cores like the apples, and they are not natives of this country, but were brought here because of their delicious fruit. Sometimes we find them growing wild, and we know how this happened. The next time we get a chance let us look for the fruit trees the birds have planted. There are a good many wild fruits that the birds are fond of, and whose seeds they are in the habit of dispersing over broad sections of country. [Illustration] SEEDS THAT ARE SHOT AWAY. OXALIS. Some plants have a way of shooting their seeds out of the pods. You know about the squirting cucumber. [Illustration: Oxalis.] The little “sheep-sorrel,” or yellow-flowered oxalis, that grows everywhere in the fields and gardens, has a way of shooting off its seeds when they are ripe. There is an elastic covering over each seed, and when the pod opens, this covering splits and suddenly curls up, with force enough to send the seed quite a distance. The leaves of the oxalis are sour, and children sometimes eat them. A very powerful poison can be extracted from them, which is called oxalic acid, and sometimes salt of lemons, but there is not enough of this poison in the leaves to make them harmful to eat. The poison when obtained in large quantities is useful in the manufacture of calico, where it is used in printing the colors, and it is also sometimes used in a diluted form to clean metal work. Be sure to look for the seed pods of the oxalis; they stand up like little candles and are very pretty. Gather some that are almost ripe and see how they shoot their seeds. [Illustration] WITCH-HAZEL.
