There is no miracle like "the burst of spring." Who has watched a tree by the window as its twigs began to shine in early March, and the buds to swell and show edges of green as their scales lengthened? Then the little shoot struggled out, casting off the hindering scales with the scandalous ingratitude characteristic of infancy. Feeble and very appealing are the limp baby leaves on the shoot, as tender and pale green as asparagus tips. But all that store of rich nutritive material is backing the enterprise. The palms are lifted into the air; they broaden and take on the texture of the perfect, mature leaf. Scarcely a day is required to outgrow the hesitation and inexperience of youth. The tree stands decked in its canopy of leaves, every one of which is ready and eager to assume the responsibilities it faces. The season of starch making has opened.
Cut some twigs of convenient trees in winter. Let them be good ones, with vigorous buds, and have them at least two feet long. You may test this statement I have made about the storing of food in the twigs, and the one about the unfolding of the leafy shoots. Get a number of them from the orchard—samples from cherry, plum, and apple trees; from maple and elm and any other familiar tree. Put them in jars of water and set them where they get the sun on a convenient window shelf. Give them plenty of water, and do not crowd them. It is not necessary to change the water, but cutting the ends slanting and under water every few days insures the unimpeded flow of the water up the stems and the more rapid development of the buds you are watching. When spring comes there are too many things that demand attention. The forcing of winter buds while yet it is winter is the ideal way to discover the trees' most precious secrets.
The Walnuts—The Hickories—The Beech—The Chestnuts—The Oaks—The White Oak Group—The Black Oak Group—The Horse-Chestnuts, or Buckeyes—The Lindens, or Basswoods
Hickories are included with their near relatives, the walnuts, in one of the most important of all our native tree groups. They are distinct, yet they have many traits in common—the flowers and the nut fruits, the hard resinous wood, with aromatic sap and leaves of many leaflets, instead of a single blade.
The walnuts are decidedly "worth knowing." All produce valuable timber and edible nuts, and all are good shade trees. Four native walnuts are well known in this country, for in October, every tree in every bit of woods is likely to be visited by school boys with bags, eager to gather the nuts before some other boy finds the tree, and thus establishes a prior claim upon it. The curiously gnawed shells outside the winter storehouse of some furry woods-dweller reveal the most successful competitor boys have, the constant watcher of the nut trees, a harvester who works at nothing else while the season is on.
