SHRUBBERY BORDER 
2. Substitute other species for those named in this planting 
plan. Such a study in substitutions will be especially desirable for 
students in sections of the country where these species are not at

This exercise is the most valuable of all and should not be omitted. 
Rather should the class work out several such plantings.
