regions 11, 12, and 13. It has large, thick, glossy leaves, and in 

 the warmer regions it is almost evergreen. It is readily trans- 

 planted, but as it is not so common in the woods as the willow oak 

 and the water oak it has not been so much used as a street tree. 



The live oak (fig. 2) is probably the noblest and most majestic 

 of the oaks of regions 12 and 13. It is evergreen and of slow growth, 

 but wherever it is found, whether on streets or in public parks, it is 

 the pride of the people. Although an evergreen, it is sufficiently 

 open headed to make a good street tree. When it becomes old it is 

 spreading, and as a rule does not form as high a head as the willow 

 oak and the laurel oak. Compared with other southern oaks it is 

 difficult to transplant. It is of sufficient merit to be used on broad 

 streets, and especially on boulevards, where the good of the future 

 as well as the present is considered. 



The mossy-cup oak or bur oak is native in the northeastern 

 part of the United States and west of the Mississippi River on the 

 hills lying between the river bottoms and the prairies west to the 

 western parts of the Dakotas and Nebraska and central Kansas and 

 Texas. It is a large, handsome tree that should prove satisfactory 

 under suburban conditions in regions 7, 8, 9, 10, and 11 and on 

 fertile well-watered soils. 



The pin oak (fig. 11, A), sometimes called the swamp oak, is a tall 

 tree, conical when youn<r, oval at maturity, with a drooping habit of 

 the lower branches. The leaves are quite finely divided and of a 

 bright glossy green. The tree comes into leaf late in the spring and 

 holds its foliage late in the fall. On many specimens the dead leaves 

 hang on through the winter, which is often objectionable. It is 

 adapted to narrower streets than the red oak, as its habit of growth is 

 not so spreading. On account of the tendency of the limbs to droop, 

 particularly as they get older> it is desirable that a good strong leader 

 should be developed, so that the lower limbs may be removed from 

 time to time as conditions require. The pin oak thrives on wet and 

 on heavy clay soils, as well as on a wide range of other soils. Figure 

 11 shows pin oaks, Norway maples, and ginkgos 18 years old on 

 adjacent streets, and illustrates the rapid growth of this oak. At 

 the time of planting these trees the pin oaks were thought to have 

 the poorest location. This tree is adapted to regions 1, 2, 3, 4, 9, 

 10. and 11. 



The red oak (fig. 19) is probably the best tree for street planting 

 in regions 1, 9, 10, and 11 and is satisfactory in regions 6, 7, 8, and 12. 

 It is a large, oval, open-headed tree of rapid growth. Under good 

 conditions a young red oak will grow 4 feet in a single season. Like 

 the other oaks it is slow in coming into leaf in the spring, but holds 

 its foliage late in the fall. The leaves usually turn a brilliant red 

 before they drop. It is comparatively free from insect and fungous 

 attacks, and it is one of the few trees really suitable for planting close
