generally, that it is always safest to plant local types of all 

 species, or those from similar climates. 



308. Sugar or Rock Maple. This is a popular shade, 

 park, and lawn tree over a large part of the Union, with 

 proper selection of varieties. The sugar maple (Acer 

 saccharinum, Wr.ugh; A. saccharum, Marsh) does well east 

 of the lakes and over a large part of the Southeastern 

 States, with some local variety variations in the South. 

 In the prairie States the trees from Eastern and Southern 

 nurseries do not thrive. On the other hand, the native 

 type known as Acer nigrum thrives on varied soil over a 

 large part of the West. But as grown from Missouri seed 

 the trees do not prove hardy in north Iowa and Minnesota. 

 Hence in improving home places, the trees should be 

 grown from locally grown seed or be obtained from as 

 nearly local timber growth as possible. 



309. Norway Maple (Acer platanoides). This, as repre- 

 sented by its many varieties, is also variable in hardiness 

 and adaptation to our varied soils and climates. The 

 nursery varieties are all desirable for ornament in the East 

 and Southeast, and the typical species is fully as hardy in 

 the prairie States as the native sugar maple. This is also 

 true of its handsome variety, Acer Schwedleri. 



310. The Dwarf Oriental Maples. The Japan maples 

 (Acer palmatum) listed in catalogues are peculiarly beau- 

 tiful as represented by a dozen or more varieties grown in 

 Eastern nurseries. They do well in deep, warm soil, 

 sheltered from drying winds, in the Eastern and Southern 

 States. But all of them fail in the prairie States. But 

 their near relatives of the Oriental type, Acer Tataricum 

 and Acer ginnala, are graceful, small trees, with handsome 

 foliage, coloring finely in autumn, and are hardy in all 

 parts of the West and the cold North.
