264 The Thorn-Tree: The Service-Beri-y. 



Several other species of this genus grow in the United States, but 

 none of them of much importance in forestry. 



The Thoen-Teee (Genus Cratcegus). 



1046. Between sixty and seventy species occur in Europe, in East- 

 ern Asia, and Japan, and in North America. About fifteen species are 

 found in Canada, the United States, and Mexico. The quality of 

 their wood is about the same as that of the apple-tree. They are of 

 slow growth, and unimportant as timber-trees, but they are in some 

 regions remarkably well adapted for hedges, being thorny, and 

 very scraggly in their growth, presenting a thicket that is quite im- 

 penetrable by man or beast. 



1047. Two species are found in California, viz., C. rivalaris and 

 G. Bouglasii. They are shrubs or small trees, the former growing 

 to 10 or 15 feet, and the latter from 18 to 25 feet, with stout spines 

 and black or dark purple fruit. 



1048. The Scarlet-Feuited Thoen (Oratoegus coccinea). This 

 thorn, when grown as a hedge-plant, should be trained to grow 

 thin and tall, which can be done best by weaving in the branches 

 in one direction, and trimming them in the other. 



1019. Dotted-Feuit Thoen (Oratcegus punctata). This is a 

 common species in the Atlantic States, growing naturally along 

 the borders of rivers, and is easily transplanted. AVhen properly 

 trimmed and managed, it makes a superior hedge-plant. The fruit 

 is dull red, or- yellowish, and dotted, and the leaves are wedge- 

 shaped, tapering below into a slender leaf-stem. 



The Seevice-Berey (Genus AmelaneUer). 



1050. Some four or five species of this genus are found in South- 

 ern Europe, Asia-Minor, Japan, and North America. Of these the 

 A. Cfawiadensis, variously known as the "shad-bush," "june-berry," 

 etc., is common in the Atlantic States, and the A. alnifolia upon the 

 Pacific coast. They are shrubs of small size, of no great interest 

 to the forester. The wood of the western species is very hard, and 

 is used by the Indians for various purposes. , The berries are dried 

 and stored away by them in large quantities for winter use. 



The Eucalyptus. 



1051. Of the genus Eueahjptm (of the natural orders Myrtacece),
