high and rocky ground the sugar maple (^4. saccharinum) 

 is excellent. It has a dense, globular crown and a formal 

 appearance. Of the smaller forms, very suitable for parks 

 and gardens, the red maple (^4. rubruni) is a most elegant 

 tree. The leaves are of medium size, whitish beneath, and 

 turn into bright yellow and scarlet tints in fall. This is 

 the best maple for general use in small grounds. The 

 striped maple (A. P ennsylvanicum) is a small tree with 

 elliptical crown, large leaves, and light, beautifully striped 

 bark. Field maple (A. campestre) has small five-lobed 

 leaves. It is a tree about twenty feet high with globular 

 crown and corymbose flowers. Tartarian maple (^4. tar- 

 taricuni) is similar in size and habit, but has almost cordate 

 leaves with very superficial lobes. 



Among forms that may be considered as large shrubs 

 only, the vine maple (A. cirdnatum) and the mountain 

 maple (^4. spicatum) are very beautiful ; the last one in par- 

 ticular is very showy when in flower, the. erect racemes 

 stand well above the foliage, and the yellow color contrasts 

 well with the tender green of the leaves. From the 

 extreme east of Asia come the beautiful dwarf varieties 

 known as Japanese maples, which are somewhat tender in 

 the north. There are several forms with more or less 

 deeply cut or highly colored foliage, varieties of Acer pal- 

 matum. Acer Japonicum and Acer Ginnala, which are 

 distinct species, are also known by the same popular name. 

 They form broad masses of highly colored leaves in 

 autumn if not injured by early frosts. 



All maples will grow in a moderately rich and moist 

 ground ; some, as the Tartarian, the field, and the sugar
