 Wood heavy, hard, strong, coarse-grained, moderately compact, very durable in contact with the soil, 



susceptible of a high polish ; layers of annual growth strongly marked by many rows of open ducts ; medullary 

 rays numerous, conspicuous; color, bright brown or red, the sap-wood lighter; specific gravity, 0.6740; ash, 0.80; 

 used for fence posts and rails, wagon hubs, construction, etc.; its value hardly appreciated. 

 Beer is sometimes made domestically by fermenting the sweet, unripe fruit (Porcher I. c.).
