AND GROUNDS. 151 



flower-beds are to be omitted. Twenty-three feet from the street, 

 and two feet from the walk on the right, plant an American Judas 

 tree, Cercis canadensis; four feet further, on the same side, the 

 European Judas tree, Cercis siliquastrutn ; opposite to them, on the 

 left side of the walk, a clean stemmed white-flowering dogwood, 

 Cornus florida. Sixteen feet from the upper Judas tree, plant a pair 

 of sassafras trees four feet apart in the same relative positions as 

 the Judas trees in the first group j opposite to them, on the left of 

 the walk, the Scamston weeping-elm, grafted eight feet high on a 

 common elm stock. The next group, sixteen feet further on, is 

 made with a pair of Kolreuteria paniculata on the right, and a 

 narrow group of low choice shrubs on the left of the walk. Very 

 //w'ffl^ evergreens, or deciduous shrubs, may be planted to the left 

 of each of these groups, as indicated on the plan, or those places 

 may be filled with single plants of rich and abundant foliage, like 

 the more robust geraniums, the Colkus verschafelti, cannas, little 

 circles of salvias, etc., etc. 



It is intended that the groups of low-growing trees which border 

 this walk shall form flat arches over head, not more than eight feet 

 over the walk ; and the trees must be reared and pruned to effect 

 this object. The Judas trees and the dogwood naturally spread 

 quite low. The study with them will be, how to draw them up so 

 that they will not be in the way over head. The sassafras, though 

 a flat-topped tree, sometimes gets too high before beginning to 

 spread. If it keeps a strong centre-stem it should be topped at 

 eight feet high to hasten its spreading. The Kolreuterias are rather 

 too large for their place, but are low-spreading trees of great deli- 

 cacy of fohage and warmth of color; and even if they finally 

 extend their branches far towards the bay-windows, the view under 

 them will be the more pleasing.
