continue with Acer, (maple and sycamore.) y^sculus, 

 (Liorse-cbestnut,) Fraximis, (ash,) Quercus, (oak,) Pi- 

 nus, (pine,) and with various otlier families. When 

 the number of hardy species is small, several genera 

 may Le collected into one clump ; but when the kinds 

 are numerous, as in Querents and Pinus, several groups 

 may be formed of one family. The dwarf species 

 will take their places in front of the others. For low 

 trees or shrubs, to fill up the margin of the taller 

 masses, we should employ the more showy species and 

 varieties of Magnolia, Cytisus, Oratagus, Arbidus, 

 Phododendron, Azalea, and others of the numerous 

 flowering shrubs and low trees procurable from nurse- 

 ries. Along with these should be planted a quantity 

 of yews, hollies, and laurels, to form masses and 

 imderwood. 



N'ote. — In most parts of the United States, limes, 

 maples, horse-chestnuts, ashs, oaks, and pines grow 

 too large, and create too much shade, when used for 

 shelters to the flower-garden. Besides this, their roots 

 extend so far as to rob the garden plants of their nutri- 

 ment, which can only be prevented by a deep, open 

 ditch between the line of trees and the garden grounds ; 

 and such a ditch is unsightly. Shrubbery of tall 

 growth is better; which may be composed of ever- 

 greens, like the rhododendron, or the privet, which is 

 perfectly hardy in our climate, and other shrubs easily 

 procured in the vicinity of almost every garden. In 

 the arrangement of these, if shrubs of different variety 

 and size are used, the taller should stand in the rear, 

 while the smaller should take the front position, and 

 the whole bank of protecting shrubbery rise, amphi- 

 theater-like, from the garden, that the eye may rest
