Beech and Oak Family (Faga- ceae). — This family includes the Beeches, Chestnuts, and Oaks. The plants of this family are monoecious trees or shrubs with staminate flowers in catkins or clusters, and pistillate flowers soli- tary or slightly clustered {Fig. 418). The fruit is a one-seeded nut partly or entirely enclosed by a covering called cupule, which is formed by bracts that develop at the base of the ovary and grow up over it. Tiie nuts of the Chestnut are common on the market and are of considerable value for food. Beech nuts contain much oil and are a good feed for hogs. From the Oaks, of which there are a large number of species, a large propor- tion of our hardwood is obtained. The beautiful figures which Oak lumber can be made to show make it a valuable wood for furniture, inside finishing of buildings, and for cabinet work. Beech wood is very hard and is used considerably for hardwood floors and in the manu- facture of furniture. Chestnut wood is soft but durable and is used for fences and buildings. The bark of Oak and Chestnut trees is rich in tannin and at one time was the source of tannin for tanning hides, of commerce is obtained {Fig. 419)..
