FOREST TREES OF THE PACIFIC SLOPE. 



black or black-purple, shiny fruit (fig. 163), sweet and edible, matures in early 

 autumn, when it is rapidly shed. Wood, fine-grained, brownish rose-red, with 

 a large proportion of sapwood. No commercial use is made of it. 



Fig. 163. — Cratccgus douglasii. 



As a chaparral cover along washable banks of streams the brushy form of 

 this haw is of considerable use. The firm, spreading roots of closely grown 

 stools hold fast and resist tendencies to erosion. Its tree form is unimportant 

 in a region where other useful trees abound.
