THE COMPLETE GARDEN 



on either side, or narrow, with a lower border, governs the type of 

 material which should be selected. Here again, with such plants as 

 the thorns and elms, a larger specimen may be used with a high head, 

 and the smaller specimens may be planted between and on either side 

 to produce the mass of foliage at the bottom. An illustration of this is 

 shown in Plate No. XXVII on Page 198. This interesting open alleeof 

 thorns and flowering dogwood is planted according to the following 

 measurements. The distance between the middle line of each row of 

 thorns is twenty-two feet s x inches. Each row was originally planted 

 with high-headed thorns at a distance of four feet six inches apart in the 

 row. Equally spaced at a distance approximating one foot six inches 

 apart, small specimens two feet to three feet high were planted in a 

 single row at a distance of one foot six inches on either side of the main 

 row of thorns. These small thorns were for the purpose of producing a 

 foliage effect beginning at the ground and extending into the higher 

 heads of the larger thorns. The width between the rows of flowering 

 dogwood is eight feet and the distance between each flowering dog- 

 wood plant in each row is eight feet. The width of the walk in this 

 picture is four feet. It is very essential to use types which have a 

 branching habit to the extreme base of the main trunk if a perfect 

 open allee is desired. 



LIST OF PLANTS FOR HEAVY FORMAL EFFECTS 



A. Border Planting. This group of trees and shrubs is composed 

 of those specimens which either lend themselves to a natural, compact 

 effect when pruned, or which possess an even, close habit of growth, 

 fitting them particularly for formal effects. Plants used for this 

 purpose should not be those which have a tendency to sucker and to 

 make any indifferent growths in different directions.
