STREET AND HIGHWAY PLANTING. 



showy orange and orange-red berries. The tree casts a very dense 

 shade which is quite cold in damp weather and should be used with 

 considerable caution. It calls for a wide road and plenty of space in 

 the parking. It needs a moist atmosphere to make its best appearance 

 and hence is generally found in the northern part of the State in a 

 better appearing condition than in the more arid south. 



THE MAPLES. 



Acer macrophyllum (Fig. 3), the native big-leaf maple, has been 

 freely planted in the parks of the southern cities but has not been tried 

 out on the street so far as could be discovered. This form is even less 

 common than Acer saccharinum (silver maple), although it far excels

it in merit. The big-leaf maple, which ranges from Oregon southward, 

 grows in the canyons of the southern part of the State to some extent 

 and has proven a fine tree in the parks. The shade is good, the foliage 

 desirable and the tree of good shape. 



In the northern and central parts of the State it is one of the best 

 street trees, although it has not been used as much as might be desired. 

 In Berkeley there are several fine plantings, notably on Piedmont ave- 

 nue, where the trees, though young, show great beauty of development. 

 As this tree is native of the coast states and is found through southern 

 Oregon, we find, as might be expected, good specimens throughout all 

 of the northern counties.
