a genus of cupbearing trees, rarely shrubs, of the north temperate zone and the countries of the tropics. There are over 200 species. The cup of the acorn is composed of numerous reduced leaves or bracts. The halyes of the acorn are seed leaves. The acorn is an article of food for man and beast. Acorns and beechnuts are together called mast. Mast is a favorite food of the bear and razor-backed hog. The Indian of southwest California and Mexico collects acorns for food. The peasants of Italy make a black bread out of acorns. In France, prior to the French Revolution, the peasants in many sections were reduced to a diet of acorn bread. Among the oaks are the cork oak, whose bark is used for corks, and the black oak, whose galls make good ink. The live oak, frequently laden with moss, bears evergreen leaves, and is best of all for shipbuilding. The bur oak is also called the mossy-cup oak by children. The white oak is the noblest oak of all. It is a handsome tree in summer when in full foliage. Its acorns are a never ending source of pleasure in autumn. It stands like a stout old giant in winter, and "when the white oak's leaves are as large as a squirrel's ear, it is time to plant corn." The elm for grace and beauty, but the old oak for qualities that endure. "Hearts of oak," "walls of oak," "strong as an oak," "stand like an oak," "the brave old oak," are expressions that show the estimate in which the oak is held. If the Anglo-Saxon people were to toast any tree it would be with the poet Chorley: Then here's to the oak, the brave old oak, Who stands in his pride alone! And still flourish he a hale old tree When a hundred years are gone!
