to the ocean, as it thrives on sandy lands only a few feet above high 

 tide or within the reach of ocean spray. 



The scarlet oak is a large, open,, round-headed tree. Its leaves 

 are more deeply divided than those of the red oak. The leaves turn 

 a brilliant scarlet in autumn, being even more gorgeous than those of 

 the red oak. This tree is adapted for street planting and is especially 

 desirable for suburban conditions in regions 1, 9, and 10. 



The swamp Spanish oak is adapted to regions 11, 12, and 13. It 

 belongs to the red-oak group, but is larger than the other oaks sug-

 but apparently it has not been tested under severe city conditions.

The valley oak is a beautiful tree for regions 2 and 3 and the more 

 favorable parts of region 5. When transplanted young, especially 

 if taken from a pot, it is easily established where there is opportunity 

 to water it for a few years. 



The water oak is frequently confused with the willow oak and 

 the laurel oak, as these three oaks are not distinguished from one 

 another except by close observers of trees. It is probably more used 

 than any other tree in the cities of region 12 and the adjoining por- 

 tions of region 11. It is the weed of the southern oaks and one of the 

 weeds of the street trees of the Southern States. It is comparatively 

 short lived and seems to be more subject to attacks of mistletoe and 

 more easily affected by windstorms than the willow oak, the Darling- 

 ton oak, and the laurel oak. This tree should not be planted, because 

 it is less desirable than the other oaks mentioned. 



The willow oak (see fig. 5), sometimes erroneously called the water 

 oak, is one of the best of the quick-growing oaks for use in regions
