for attractive groupings of trees and shrubs. On a 

 south bank, a mixture of hemlocks and birches would 

 be pleasing, with a ground covering of yews and ferns 

 in certain places. On the sunny north slopes, 

 if one desired rich autumn coloring, one could not 

 do better than to select sugar maples anywhere 

 in the northern portion of the eastern half of the 

 United States. Other trees 'noted for their fall 

 coloring, but found in a more restricted area, in- 

 clude sassafras, tulip trees, birches, white ash, sweet 

 gum, flowering dogwood, pepperidge, blue beech, 

 pin cherries, and some of the oaks. The stag- 

 horn sumac,- which often grows to the size of a 

 small tree, is rich in color and so are all the other 

 sumacs. The shrubby dogwoods turn purple, red, 

 and yellow. The common hazel is often wonder- 

 ful in color. Other maples help to make Ameri- 

 can autumns glorious, the red maple being es- 

 pecially brilliant in certain portions of New Eng- 

 land, where it is frequently accompanied by the 

 equally brilliant blueberry. All of the above na- 

 tive trees are suitable for planting about artificial 

 lakes when these are extensive enough to provide 

 space along their borders for both openings and 

 woods.
